Cause | Elimination Method |
When the starter is turned on, the armature does not rotate, the traction relay does not work | |
Faulty or completely discharged battery | Charge battery or replace |
Pole conclusions of the storage battery and tips of wires are strongly oxidized; loose tips | 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 the plug «50» starter and battery |
Contacts do not close «30» and «50» ignition switch | Replace the contact part of the ignition switch |
Traction relay armature sticking | Remove the relay, check the ease of movement of the armature |
Faulty starter enable relay | Clean the relay contacts. Replace defective relay |
Break in the power circuit of the winding of the starter enable relay | Check the wires and their connections in the circuit between the plug «50» ignition switch and plug «86» relay |
When the starter is turned on, the armature does not rotate or rotates too slowly, the traction relay trips | |
Faulty or discharged battery | Charge battery or replace |
Pole terminals of the battery and wire lugs are oxidized; loose tips | Clean terminals and wire lugs, tighten and lubricate with Vaseline |
The fastening of the tips of the wire connecting the power unit to the body or to the outlet has loosened «minus» battery | 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 stator or armature windings | Replace stator or armature |
Brush holder short circuit «positive» brushes per mass | Repair the short or replace the cap on the manifold side |
When the starter is turned on, the traction relay is repeatedly activated and disconnected | |
Discharged battery | Charge your battery |
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» starter |
Breakage or short circuit in the holding winding of the traction relay | Replace traction relay |
When the starter is turned onanchor rotates, flywheel does not turn | |
Freewheel slip | Check the starter on the stand, replace the clutch |
Breakage of the clutch engagement lever or jumping out of its axis | Replace the lever or reinstall its axle |
Breakage of the clutch drive ring or buffer spring | Replace clutch |
Unusual starter noise when turning the armature | |
Loose starter mount or broken cover on the drive side | Tighten the mounting nuts or repair the starter |
The starter is fixed with a warp | Check starter mount |
Excessive wear on bearing bushings or armature shaft journals | Replace starter |
Loose stator pole (anchor touches the pole) | Tighten the screw fixing the pole |
Damaged gear teeth or flywheel ring | Replace drive or flywheel |
The gear does not disengage from the flywheel: | |
- jamming of the drive lever | - replace the lever |
- jamming of the clutch on the splines of the armature shaft | - clean the splines and lubricate them with engine oil |
– weakened or broken clutch or traction relay springs | – replace clutch or traction relay |
- the retaining ring has come off the clutch hub | – replace damaged parts |
– jamming of the armature of the traction relay | – replace the traction relay or eliminate jamming |
- the contact part of the ignition switch is faulty: the contacts do not open "30" And "50" | – Check up correctness of closing of contacts at various provisions of a key; replace defective contact part |
