| Cause of malfunction | 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, and the tips are loosely tightened | Clean the terminals and wire ends, tighten and lubricate with Vaseline |
| Interturn short circuit in the pull-in winding of the traction relay, its short circuit to ground or break | 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 |
| The ignition switch contact part is faulty: contacts "30" and "50" 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 tips are oxidized, the tips are loosely tightened | Clean the terminals and wire ends, tighten and lubricate with Vaseline |
| The fastening of the wire ends connecting the power unit to 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 armature winding | Replace the anchor |
| When the starter is turned on, the traction relay repeatedly operates and switches off | |
| The battery is discharged | Charge the battery |
| Open or short circuit in the holding winding of the traction relay | Replace the traction relay |
| 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 |
| 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 |
| The gearbox gears are damaged | Replace damaged gears |
| Unusual noise from the starter when the anchor is rotating | |
| Excessive wear of the anchor and drive shaft bearing liners | Replace liners or covers and bearings with liners |
| Excessive wear of the drive shaft bushing in the clutch housing | Replace the bushing |
| The starter mount has become loose or its cover on the drive side is broken | Tighten the mounting nuts or replace the starter |
| The starter is mounted at an angle | Check the starter mount |
| The gearbox gears are damaged | Replace damaged gears |
| The teeth of the drive gear or flywheel ring gear are damaged | Replace the drive or flywheel |
| The gear does not disengage from the flywheel: clutch jamming on drive shaft splines traction relay anchor jamming |
Please do the following: clean the splines and lubricate them with motor oil replace the traction relay or eliminate the jamming |
