Cause | Method of elimination |
When the starter is turned on, the anchor does not rotate, the traction relay does not operate | |
The battery is faulty or completely discharged | Charge the battery or replace it |
The battery terminals and cable tips are heavily oxidized; the tips are not tightened properly | Clean the terminals and wire ends, tighten and lubricate with Vaseline |
Interturn short circuit in the pull-in winding of the traction relay, short circuit to ground or open circuit | Replace the traction relay |
Open circuit in the power supply circuit of the starter traction relay | Check the wires and their connections in the circuit between the "50" plugs of the starter and the ignition switch |
Contacts "30" and "50" of the ignition switch do not close | Replace the ignition switch contact part |
Traction relay anchor jamming | Remove the relay, check the ease of movement of the anchor |
When the starter is turned on, the anchor does not rotate or rotates too slowly, the traction relay is triggered | |
The battery is faulty or discharged | Charge the battery or replace it |
The battery terminals and wire ends are oxidized; the tips are not tightened properly | Clean the terminals and wire ends, tighten and lubricate with Vaseline |
The fastening of the wire ends connecting the power unit to the body or to the negative terminal of the battery has become loose | Tighten the wire end caps |
The contact bolts of the traction relay are oxidized or the nuts securing the wire tips to the contact bolts are loose | Clean the contact bolts, tighten the wire fastening nuts |
Commutator burnout, brushes sticking or wearing out | Clean the commutator, replace the brushes |
Open or short circuit in the stator or armature windings | Replace stator or armature |
Short circuit of the brush holder of the "positive" brush to ground | Fix the short or replace the cover on the manifold side |
When the starter is turned on, the traction relay repeatedly it works and turns off | |
The battery is discharged | Charge the battery |
Large voltage drop in the traction relay power supply circuit due to severe oxidation of the wire tips | Check the wires and their connections in the circuit from the battery to the "50" plug of the starter |
Open or short circuit in the holding winding of the traction relay | Replace the traction relay |
When the starter is turned on, the anchor rotates, the flywheel does not rotate | |
Freewheel clutch slippage | Check the starter on the stand, replace the clutch |
Breakage of the clutch engagement lever or its axis popping out | Replace the lever or reinstall its axle |
Broken clutch ring or buffer spring | Replace the coupling |
Unusual noise from the starter when the anchor is rotating | |
The starter mount has become loose or its cover on the drive side is broken | Tighten the mounting nuts or repair the starter |
The starter is mounted at an angle | Check the starter mount |
Excessive wear of bearing bushings or anchor shaft journals | Replace starter |
The stator pole mount has become loose (the anchor touches the pole) | Tighten the pole mounting screw |
The teeth of the drive gear or flywheel rim are damaged | Replace the drive or flywheel |
The gear does not disengage from the flywheel: | |
– jamming of the drive lever | - replace the lever |
– clutch jamming on the splines of the armature shaft | – clean the splines and lubricate them with engine oil |
– the clutch or traction relay springs are weakened or broken | – replace the clutch or traction relay |
– the retaining ring has slipped off the clutch hub | – replace damaged parts |
- jamming of the traction relay anchor | - replace the traction relay or eliminate the jamming |
– the ignition switch contact part is faulty: contacts "30" and "50" do not open | – check the correctness of the contact closure in different key positions; replace the faulty contact part |
