Cause of malfunction | Remedy |
When the starter is turned on, the armature does not rotate, the traction relay does not work | |
Faulty or completely discharged battery | Charge the battery or replace it |
Pole terminals of the battery and wire lugs are strongly oxidized, the lugs are loosely tightened | Clean terminals and wire lugs, tighten and lubricate with Vaseline |
Interturn short circuit in the retracting winding of the traction relay, its short circuit to ground or open circuit | Replace traction relay |
Open in the power circuit of the starter traction relay | Check the wires and their connections in the circuit between plugs "50" of the starter and the ignition switch |
The contact part of the ignition switch is faulty: contacts "30" and "50" do not close | Replace the contact part of the ignition switch |
Traction relay armature sticking | Remove the relay, check the ease of movement of the armature |
When the starter is turned on, the armature does not rotate or rotates too slowly, the traction relay trips | |
Faulty or discharged battery | Charge the battery or replace it |
Pole terminals of the battery and wire lugs are oxidized, the lugs are loosely tightened | Clean terminals and wire lugs, tighten and lubricate with Vaseline |
The fastening of the tips of the wire connecting the power unit to the battery has loosened | Tighten the wire lugs |
The contact bolts of the traction relay are oxidized or the nuts for fastening the wire lugs on the contact bolts are loosened | Strip the contact bolts, tighten the wire fastening nuts |
Commutator burning, brushes sticking or wear | Clean manifold, replace brushes |
Open or short in armature winding | Replace anchor |
When the starter is turned on, the traction relay is repeatedly activated and disconnected | |
Discharged battery | Charge your battery |
Breakage or short circuit in the holding winding of the traction relay | Replace traction relay |
A large voltage drop in the power supply circuit of the traction relay due to strong oxidation of the wire tips | Check the wires and their connections in the circuit from the battery to the plug "50" of the starter |
When the starter is turned on, the armature rotates, the flywheel does not rotate | |
Freewheel slip | Check the starter on the stand, replace the clutch |
Gearbox damaged | Replace damaged gears |
Unusual starter noise when turning the armature | |
Excessive wear of the armature and drive shaft bearing shells | Replace liners or covers and bearings with liners |
Excessive wear of the drive shaft bushing in the clutch housing | Replace bushing |
Loose starter mount or broken cover on the drive side | Tighten mounting nuts or replace starter |
The starter is fixed with a warp | Check starter mount |
Gearbox damaged | Replace damaged gears |
Damaged gear teeth or flywheel ring | Replace drive or flywheel |
The gear does not disengage from the flywheel: jamming of the coupling on the splines of the drive shaft traction relay armature sticking |
Do the following: clean the splines and lubricate them with engine oil replace the traction relay or eliminate the jam |
