Chapter 1: What is a starter solenoid
[/mk_fancy_title][vc_column_text css=".vc_custom_1512967728785{margin-lesser: 0px !important;}"]
What is a Starter Solenoid
A starter solenoid is a combination of solenoid and switches (Total name: Starter Solenoid Switch). It is one of the main components of the motorcar starter (Motor, Starter Bendix Bulldoze, Starter Solenoid)
As we all know, the starting of the engine requires external support, and the car starter is playing this office. In full general, the starter uses iii components to achieve the unabridged starting process.
- The motor receives electric electric current from the battery and brand the starter drive gear generate mechanical motility;
- The Bendix drive engages the pinion gear into the engine flywheel and disengages automatically after the engine start.
- And the starter's on/off function is controlled by the starter solenoid.
Starter Solenoid Functions
Starter Solenoid has two functions:
1. To control the start excursion on / off (Connect the battery to the starter)
two. Drive the starter pinion engaging in the flywheel ring gear.
Function 1
When turn on the ignition switch and the starter circuit is turned on, the electric current flows to Starter Solenoid and create the electromagnetic forcefulness.
The electromagnetic strength of the solenoid switch sucks the movable fe cadre in the Starter Solenoid to contact the two terminals, one of which connect to the positive pole of the bombardment and the other terminal to the starter.
Part ii
The electric current divides into ii streams flowing through the Starter Solenoid:
A ). A stream flow through the sucking coil, generating a magnetic force to sucks the movable fe core and move the fork astern so that the starter pinion can engage the engine flywheel.
B). The another stream flows through the holding coil, creating a magnetic strength to go along the core in the post-pulling position until the starting complete.
Where is the starter solenoid
In a auto starter motor with Starter Solenoid, the Starter Solenoid is commonly mounted directly on the to of starter motor. And so where is the starter motor, where is the starter solenoid.
Starter Solenoid Operation
The whole process of starter solenoid switch tin can exist divided into iii stages: Sucking, property, return.
(i) Sucking
When the ignition switch turns to the Get-go position, the bombardment current flows to the sucking curl and concur whorl.
The electric current then flows from the sucking coil to the armature roll thus make the coil rotated at a depression speed.
In this way, the movable core of the solenoid switch sucks into the cadre.
Through the sucking operation, the starter drive pinion will be pushed out and engaged with the ring gear. As well, the contact plate closes the main contact point.
(2) Holding
When the main contact bespeak of the plate close, no current flows through the sucking scroll. So, the magnetic field coil and the armature coil tin can become the electrical current directly from the battery.
The armature curlicue then begins to rotate at loftier speed, and the engine starts.
Because no current flows through the sucking coil, and then the moving iron core tin only hold the coil in a fixed position past the magnetic force.
(3) Return
When the ignition switch turns from START to ON, the current flows from the primary contact side to the property coil via the sucking coil.
In this point, since the magnetic strength formed by the sucking whorl and the holding whorl neutralize each other, they lose the forcefulness to concord the movable core.
Thus, the plunger is pulled back by the render leap force, and the contact plate is asunder, the starter stops.[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1498088701961{background-color: #f2f2f2 !important;}"][vc_column][mk_fancy_title color="#000000″ size="41″ font_weight="900″ margin_top="20″ font_family="Patua+1" font_type="google" marshal="center"]
Chapter 2: Starter Solenoid Troubleshooting
[/mk_fancy_title][vc_column_text css=".vc_custom_1532476334345{margin-bottom: 0px !important;}"]
Starter Solenoid Bug
The starter solenoid has 4 mutual bug:
ane) The suction fails occasionally, or works in engine cooling merely and fails in engine warming up.
2) When starting up, the starter solenoid can not reset. Release the start button, the starter remains in operation and but stops when power off.
3) The rubberband force of the return spring weakens after repeated employ, resulting in that the drive gear of one-way clutch cannot be restored timely, but driven and reversely dragged by the flywheel ring gear.
iv) When the starter starts, it will make a periodic noise from the starter solenoid, merely the starter does not rotate.
Symptoms of a bad starter solenoid
A multimeter is needed to test and verify the problems of the starter solenoid, but before the testing, the following table can be used to make up one's mind whether the starter solenoid works:
[mk_table]
| Fault symptom | Possible reasons for the failure |
| The starter solenoid make the clicking noise continuously | The starter solenoid holding coil keep holding or the contacts sealing-off |
| Afterwards switching on the starter, the starter solenoid makes the clicking noise, slightly moves simply does not rotate. | a.The connection betwixt the solenoid and starter is defective b.Starter solenoid is broken |
| The start button has disengaged, and the drive gear has returned, but the starter continues to rotate. | The starter solenoid contact burn-out |
| The offset push button is disengaged, the starter continues to rotate, but the drive gear tin can non reverse. | The starter solenoid has contact burnt, or the movable atomic number 26 core and return spring cannot move due to no plenty elastic force(poor quality) |
[/mk_table]
Test a starter solenoid with a multimeter
Set the multimeter punch to continuity mode, connect the multimeter probes to the solenoid terminal mail service( the one used to connect to the motor trunk) and the solenoid shell.
If there is a resistance, so the belongings ringlet is adept.
If the resistance is zero, and so the circuit might be shorted.
If the resistance is space, then the excursion could be broken. If there is a short circuit or broken circuit, you should supercede the starter solenoid.
If your multimeter has the continuity mode, it will exist even easier to figure out your starter solenoid condition past testing the continuity of each connection.
Ready the continuity mode, cheque the continuity between Terminal Southward and M. If there is a continuity,(The screen displays a value of zero (or well-nigh aught), and the multimeter beeps. ) supersede the solenoid.
Set the continuity mode, bank check the continuity between Terminal South and the automobile torso. If there is no continuity(The screen will display 1 or OL (open loop).), supersede the solenoid.
Fix the continuity mode, check the continuity betwixt Terminal M and B. If there is continuity(The screen displays a value of zero (or near zero), and the multimeter beeps. ), supersede the solenoid.
Starter Solenoid No-load Examination
1.Starter Solenoid Sucking Coil Exam
Disengage the outer lead of the starter field winding (Terminal C, meet Fig. below), connect the positive pole of the car bombardment to Concluding l, and negative pole to the starter Terminal C and the crush.
At this point, the drive gear should motion forward.
If not, the solenoid sucking ringlet is very probable damaged.
2. Starter Solenoid Property Gyre Test
If the drive gear in the previous test tin motility forwards, and so disconnect the Last C and connect it to the wire of the battery concluding negative, as shown in Effigy, the drive gear should remain exterior.
If the drive gear reverses, it indicates that the solenoid belongings coil is damaged.
3. Starter Solenoid Leap Test
Based on the higher up test, undo the vanquish wire connected to the battery concluding negative, as shown in Figure below.
Normally, when the battery terminal negative is disengaged, the drive gear should reverse speedily.
If the drive gear cannot reverse, it indicates that the solenoid return spring is damaged.
Troubleshooting/test a starter solenoid with a screwdriver
A screwdriver tin can also exist used to test the starter solenoid if you don't have a multimeter.
And it likewise is a quick and easy method to diagnose the solenoid starter solenoid clicking dissonance problems.
Connect the two terminal posts of the starter solenoid with a screwdriver, if the starter does not rotate, the malfunction lies in the starter. If the starter functions well, the malfunction lies in the solenoid switch and is often caused by the ablation of the starter solenoid contacts.
As well, you tin attempt to shake the connecting line of the car bombardment and the starter, if the starter functions well, then the starting circuit might exist in a poor contact. If so, y'all should bank check the high temperature or the sparking parts in the starting organization circuit.
Bypass Starter Solenoid: Commencement motorcar with a bad starter solenoid
Sometimes the starter could not rotate, or the rotate speed is low later on switch on (brightness of the headlamp is fine), and when the starter stop to rotate, there is strange chugging noise nigh the starter motor, it indicated that the starter solenoid switch got a problem.
If the solenoid switch got some issues when yous are driving, yous could use a lead wire to make an emergency starting circuit.
Simply connect the battery final anode and concluding B of the starter by a lead wire.
Later on the excursion is well continued, turn the ignition switch to showtime position, the starter would work and start the automobile engine.
Remember to disconnect the wire immediately once the car starts, and detect the closest repair shop as soon as possible to ready the starter solenoid problem.[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1500084984306{background-colour: #ffffff !important;}"][vc_column][mk_fancy_title colour="#000000″ size="41″ font_weight="900″ margin_top="20″ font_family="Patua+One" font_type="google" align="middle"]
Chapter 3: Starter Solenoid Wiring Diagram
[/mk_fancy_title][vc_column_text css=".vc_custom_1513217848962{margin-lesser: 0px !important;}"]
Starting Organisation Wiring Diagram
Firstly, permit's check the of the starting system circuit, the wiring diagram every bit shown in the Fig. below. There is a connection between the starter, the car battery, and the ignition switch. The working circuit of the starter can be activated later the ignition switch is on.
The starting arrangement wiring diagram is as shown in beneath prototype.
While the ignition switch is non turned to the outset position, the starter solenoid will not connect to the start circuit, and the starting gear is separated from the flywheel. Once the ignition switch is turned to the start position, the magnetic gyre excursion will connect to the circuitry.
The sucking coil circuit is as below:
Motorcar battery anode (+) > fuse > ignition switch (start position) > solenoid final 50 > sucking coil > terminal c of the solenoid switch > field roll > positive brush > armature coil > negative castor > footing wire > storage battery cathode(-)
The belongings coil excursion is as below:
Storage battery anode > fuse > ignition switch (first position) > solenoid last l > belongings coil >ground wire > car battery cathode (-)
Afterward current passes through the sucking coil and holding ringlet, as the current management is identical, the magnetic field is superimposed, the iron core will be sucked in.
And so, the iron core will drive the starter drive clutch to motion backward and so that the starter gear tin mesh with the engine flywheel.
While the starter gear well-nigh completes the meshing (with the flywheel), the iron cadre will move forward to a detail position, to brand the contact panel touch with the contacts. Thus the starter solenoid switch will turn on.
Afterward the starter gear has completely meshed with the flywheel, the fe core volition move forward to an extreme position, and the solenoid switch will be pressed tightly and connect to the machine starter. In the finish, the starter motor rotates, and the engine starts driven by starter drive.
The starter motor circuit is as beneath:
motorcar battery anode(+) > solenoid switch concluding 30 > contact panel > solenoid switch concluding C > field coil > positive brush > armature roll > negative castor > basis wire > car bombardment cathode(-)
When the concluding 30 & C of starter motor are connected, the pull-in curl will brusque out. The position of the iron core afterwards suction can be maintained merely past the magnetic force of the holding coil.
When the ignition switch turns back to On position after cranking the engine, the starting circuit will plow off, and the starter will stop rotating. The starter drive gear returns past the leap, the starter drive gear, volition dissever with the engine flywheel.
Starter Solenoid Wiring Diagram
Non every car bear the starter relay in starting system, and the starter solenoid wiring diagram tin be learned by with or without starter relay type.
1. Starter Solenoid Wiring Diagram – Without Starting Relay Type
The starting organization excursion without starter relay set in is shown in Fig. below.
Afterward turn on the ignition switch, terminal 50 of the ignition switch is continued to the B8 node of the central excursion board via the red or blackness wiring, then to the solenoid terminal 50 of the starter via the C18 node of the central circuit board. The battery anode (+) is connected to terminal 30 of the starter via the black wiring.
When turning the ignition switch to the start position, the current direction is as below:
Car battery anode(+), ignition switch start gear, terminal 50, sucking curlicue, final C, field winding, armature winding, basis wire, car battery cathode(-)
Meanwhile, the current direction that passes through the property gyre is as beneath:
car bombardment anode(+), ignition switch start gear, terminal 50, belongings coil, bonding, car bombardment cathode. (The working process has been introduced before in Starting Arrangement Wiring Diagram)
two. Starter Solenoid Wiring Diagram – Without Starter Relay Type
To protect the ignition switch, lots of mod cars apply the starter relay to command the starter solenoid. The starter solenoid wiring diagram with starter relay shows in the following Fig.
When the ignition switch has not turned to the start gear, no current volition passes through the relay coil, and the starter relay contacts are open. Likewise, the starter solenoid is not energized, and the drive gear is separated from the flywheel ring gear.
Later on turning the ignition switch to the start position, the circuit of the starter relay coil volition be conductive, and the electric current direction is as below:
Afterwards turning the ignition switch to the starting time position, the circuit of the starter relay curl will be conductive, and the electric current direction is as below: car battery anode > ignition switch concluding 1 > ignition switch concluding 3 > starter relay terminal (The 1 use to connect to ignition switch) > coil ground wire > car battery cathode.
After the starter solenoid coil is conductive, the starter relay contacts volition be airtight, and connect to the sucking roll and belongings coil circuit. (The working process has been introduced earlier in Starting System Wiring Diagram)
In the starting arrangement with an electronic-controlled engine, the ground terminal of the starter relay roll is connected to the neutral position of the ignition switch (cars with automatic transmission can simply kickoff the engine in the position P & Due north ) or the interlock switch of the clutch, as shown in the left Fig.[/vc_column_text][vc_column_text]
Starter Solenoid Wiring
How to wire a starter
Nearly of the solenoids are installed direct on the starter, and they are closely related to each other. Hence, earlier learning how to wire a starter solenoid, the starter's wiring should be studied.
A 4-terminal starter has two thick terminals and ii thin ones, information technology might be a little confused to find out which is which if y'all are not a professional.
The 2 thick terminals post
One of the ii thick terminals posts is connected to the automobile battery, and the other is connected to the field winding inside the starter via the conducting plate on the shell of the starter.
Therefore, the thick terminal mail service with conducting plate shall be connected to the field winding, while thick terminal postal service without conducting plate shall be connected to the car battery.
Simply if the conducting plate is not in that location, how to distinguish between the 2 thick terminals, then?
Actually, the sucking curlicue inside the starter solenoid switch is connected to one of the thick terminals via the welding spot, then to the field winding, the armature winding and finally to the negative brush bonding. Therefore, the thick terminal with i thread stop should be connected to the field winding, while thick terminal without thread cease should exist continued to the automobile battery.
The 2 thin terminals mail
The concluding mail with 2 thread ends (the sucking gyre and property gyre are welded together via the welding spot then continued to the sparse terminal) is pull-in terminal, (namely, the solenoid concluding)
The other thin concluding post is straight connected to the shrapnel within the motor, so sparse concluding without thread stop is the ignition switch terminal.
How to wire a starter solenoid
There are iii terminals on the solenoid insulating comprehend (also called starter solenoid cap), those are, terminal B (or xxx), terminal M (or C) and start concluding Due south (or l).
Sometimes, there are 4 terminals on the solenoid cap, and those are: terminal B (or 30), concluding M (or C), start final S (or 50) and ignition terminal R (or 15a), as shown in Fig below.
Terminal B and Terminal M are usually copper bolts with a thickness of 8mm or 10mm, the ane with lug plate is terminal Yard, which is the power supply terminal of the motor field winding; the other ane is terminal viii, which is the power line terminal of the car battery.
First final S and ignition final R are commonly iron bolts with a thickness of 4mm or 5mm, the one with lug plate is starting concluding S, the electric wire of which is led to the starter relay; the other one is ignition last R, the electric wire of which is led to the boosted resistance of the ignition coil. The solenoid shell is also an invisible concluding 31(the ground wire).
The switch part of starter solenoid is composed of a main contact plate and contacts. The principal contact plate is stock-still to the forepart of the movable fe core push rod, and the two contacts are respectively integrated with the double-spiral bolt of the connecting lead terminal C and the power supply terminal xxx.
Virtually the switch contacts, in that location is an boosted resistance short excursion switch fabricated of a small copper sheet, which is connected to the final 15a.
The inner structure of the solenoid is shown in the left Fig.[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1500084993763{background-color: #f2f2f2 !important;}"][vc_column][mk_fancy_title color="#000000″ size="41″ font_weight="900″ margin_top="20″ font_family="Patua+1" font_type="google" align="heart"]

[/mk_fancy_title][vc_column_text css=".vc_custom_1512967499990{margin-lesser: 0px !important;}"]
Starter Solenoid Replacement
If y'all want to replace your starter solenoid, you have to take out the starter motor from your vehicle first. The location of the starter motor can be differed by auto models, the following instruction is the regular way to replace a starter solenoid. The step ane-7 is about removing a starter motor and step 8-11 near supplant a starter solenoid.
Pace 1. Disconnect the car bombardment negative cable
Step ii. Lift the vehicle if the starter motor is nether the car.
Step 3. Remove the nut in the starter solenoid final.
Footstep 4. Dismount the terminal of the cablevision of the automobile battery anode from the starter.
Step 5. Remove the nut in the starter solenoid concluding S.
Pace 6. Remove the retaining bolts in the starter.
Stride vii. Take out the starter.
Step 8. Unscrew the retaining nut of the solenoid final, as shown in the pictures below.
Step 9. Unscrew the two nuts that fix the solenoid to the shell of the starter Bendix drive and remove the solenoid. Equally shown in the following film.
Stride 10. Install the new starter solenoid according to the opposite procedure of removing the solenoid.
As shown in the above figure, hook the plunger hook to the starter fork, then use retaining bolts to install the starter solenoid to the starter vanquish. Notation and marker the installation management of the starter solenoid before the disassembly, if install in the opposite position, the starter volition not operate. Connect the motor lead, install and gear up with a nut.
Pace 11. Starter Solenoid Retesting
After the solenoid is installed, connect the corresponding circuit. The no-load exam tin can be carried out on the car battery to verify the maintenance consequence of the starter. The starter tin exist installed on the vehicle after it operates well in the no-load test. The retest way is every bit same every bit the Starter Solenoid No-load Test in Affiliate two.
Stride 12. Install the starter motor according to the reverse procedure of removing the starter motor (Step seven-i).
Caution: 5 Tips for replacing a starter solenoid
1. If you lose the retaining commodities of the starter, you should be careful with the length of the new bolt, in example that over-long bolt bursts the gyre former (some models of solenoids will not have this fault) and induces ground loop. Besides, recall to use a spring washer when installing the commodities.
two. The current of the starter is big in operating and last B and final M volition overheat considering of that. And then recall to use a spanner to tighten the terminal nuts while you are maintaining your starter solenoid.
three. To avert the bad contact, the atomic number 82 wire of the final B and terminal 1000 should be clamped with ii flat washers.
four. The two retaining bolts in the solenoid comprehend contacts are quite piece of cake to loose due to the starter vibrating, then they should exist tightened whenever maintaining the starter.
5. To reduce the resistance of the movable iron cadre at piece of work, a thin layer of engine oil should be coated on the surface of the core (anti-freezing engine oil should exist used in winter).
Starter Solenoid Price
The starter solenoid prices are differed by unlike models, quality, and manufacturers. Meanwhile, larger solenoids (such as the Heavy Duty serial starter solenoid) tend to be more than expensive than smaller ones.
The all-time is definitely the OEM starter solenoid, and solenoids in the aftermarket are relatively cheaper.
When I was writing this guide, I establish a quite interesting book, and in that location are many electrical accessories' prices recorded in the book. Role of the starter solenoid prices are as follows:

Chapter v: How to repair a starter solenoid
[/mk_fancy_title][vc_column_text css=".vc_custom_1512967612006{margin-lesser: 0px !of import;}"]Most of the broken starter solenoid switches are repairable, only the labor charge of repairing a solenoid switch tends to be higher than the solenoid switch itself, the repair shops are reluctant to repair the switches, instead of straight replacement is adopted.
We do not recommend not-professionals repair the switches by themselves. The post-obit content is for reference simply to those with certain experience. Non-professionals shall seek assist from the local mechanic.
Starter Solenoid Disassemble
1.Pull out the movable fe core and leap from the rear end.
2.Seal off the soldering tin at the connection strap of the solenoid box with soldering iron, and so that the solenoid coil articulation can trip out.
3.Unscrew the ii retaining bolts of the switch cap, carve up the starter solenoid cap from the solenoid housing, and pull the solenoid axle assembly parts out from the housing(solenoid shell).
Basic Starter Solenoid Repair
ane. Starter Solenoid Stuck Issue
The movable atomic number 26 core should be able to motility smoothly. If not, you should discover the problem(southward) that cause the stuck and set up information technology. Supplant the leap if it'southward non in proficient status. In about cases, the stuck consequence is caused past the bad spring.
2. Starter Solenoid Contacts & Contact Plate burn-out
If the solenoid contacts are not fire-out very severely, and so simply apply the sandpaper to smooth the surface of the solenoid contacts & contact plate.
If the surface is burn-out severity, you should open the solenoid cap, have out the contacts & contact plate, and file the contacts or add the flat washer(s) till 2 contacts are in same height.(The heights of the two contacts in the switch cap should be consistent)
three. Thread damage of B/Chiliad terminal bolts
The terminals unremarkably adopt M8 or M10 copper bolts. The traditional repair method is to dismantle the starter and starter solenoid from the vehicle, detach the solenoid, unscrew the terminal commodities, and use the threading die to rethread the terminal bolts.
Starter Solenoid Advanced Test
one.Starter solenoid coil inspection:
Utilize the R1(Resistance) scale of the multimeter to measure the resistance of the pull-in coil and the holding coil of the solenoid, and the resistance value shall be same with the starter solenoid specification.
If the resistance R=∞, the roll is disconnected.
If the resistance is lower than the specified value, the scroll has a error of turn-to-turn short circuit.
(ii) Starter Solenoid Working Performance Inspection:
a. Inspection of pull-in and drib-away voltage of solenoid: When inspecting, deport out wiring co-ordinate to the circuit shown in the right Figure.
Firstly turn on the switch, gradually increase the voltage, when the multimeter (resistance scale) indicates a resistance of cypher, the indicated value of voltmeter Five is the pull-in voltage of the switch.
And so gradually reduce the voltage indicated value, when the multimeter indicates a resistance of space, the indicated value of the voltmeter is the dropout voltage of the switch.
The pull-in voltage shall not exceed 75% of the nominal voltage, and the dropout voltage shall not exceed twoscore% of the nominal voltage.
b. The ignition ringlet additional resistance brusque-circuit switch inspection:
The testing excursion for the brusque-circuit switch is shown in Fig.2-28. When turning on the switch, the indicator light in the circuit should be brightened up.
c. Starter Solenoid Outage performance Inspection:
When the starter drive gear is stationary and stays in the engaged position, cut off the solenoid ability supply. At this time, the main contact of the solenoid shall be able to exist interrupted chop-chop.
Based on the inspections above, solenoids with poor or unqualified performance should be repaired or replaced.
Starter Solenoid Coil Rewinding
(i) Seal off the soldering tin on the connection strap of the switch cap and remove the switch cap.
(two) Clamp the switch housing on the bench spiral, unclench the riveting edge of the switch with a screwdriver, and take out the curlicue associates.
(3) Dismantle the burned-out curlicue (if you do not accept the specific data, you should record the coil diameters, the number of turns and winding direction of the old ringlet usher).
Check the curlicue frame and the insulating pressing plate; if there is impairment, you lot should repair information technology according to the original shape.
(4) When rewinding the curlicue, the bore, the number of turns and the winding direction of the wire should exist identical to the original ones.
In general, the holding coil (sparse) is in the inner layer, and the pull-in coil (thick) is in the outer layer, the two coils have the same winding management, and fish paper should exist used to separate the coils and to separate the curl frame and the housing.
(5) The positions of the four outgoing thread end on the two coils shall be distributed as the right effigy(a).
Insulation tube shall be sheathed on the ends to foreclose the insulation varnish of the wires from wearing out.
(vi) Put the felt, coil assembly and iron plate in the switch housing and rivet them properly. And then twist the ends one and ii of the ii coils together, and weld starting end 4 of the sparse coil on the iron plate (see right image b).
(7) Assembling the contact plate and the switch cap, put out the stop 1 and 2 of the coils from the connectedness strap pigsty of the solenoid terminal and weld firmly. Pulling out the starting end 3 of the thick coil from the strap hole of the fixed contact plate and weld firmly (see right image c).
In the end, remember to retest the starter solenoid after fixing starter solenoid.(Refer to Chapter two)[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1498096012414{background-color: #f2f2f2 !important;}"][vc_column][vc_column_text css=".vc_custom_1513217365415{margin-lesser: 0px !important;}"]Nosotros're now at the stop of The Definitive Guide of Starter Solenoid.
