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 Pole terminals of the battery and wire lugs are strongly oxidized or the lugs are loosely tightened Interturn short circuit in the retracting winding of the traction relay, shorting it to «mass» or break Open in the power circuit of the starter traction relay The contact part of the ignition switch is faulty: the contacts do not close «30» And «50» Traction relay armature sticking Auxiliary starter relay damaged Malfunction in a chain of management of the additional relay of a starter | Charge the battery Clean terminals and wire lugs, tighten and lubricate with Vaseline Replace starter relay Check the wires and their connections in the circuit between the plugs «50» starter and ignition switch Replace the contact part of the ignition switch Remove the starter traction relay, check the ease of movement of the armature Replace starter relay Check the wires and their connections between the auxiliary starter relay and the controller. If no fault is found, replace the controller |
When the starter is turned on, the armature does not rotate or rotates too slowly, the traction relay trips | |
Faulty or discharged battery Pole terminals of the battery and wire lugs are oxidized, the lugs are loosely tightened The fastening of the tips of the wire connecting the power unit is loosened (engine) with body The contact bolts of the starter traction relay are oxidized or the nuts for fastening the wire lugs on the contact bolts are loosened Burning of the starter collector, hanging brushes or their wear Open or short circuit in the winding of the starter armature | Charge the battery Clean terminals and wire lugs, tighten and lubricate with Vaseline Tighten the lugs of the wire connecting the power unit (engine) with body Strip the contact bolts of the starter traction relay, tighten the wire fastening nuts Clean the starter manifold, replace the brushes Replace starter anchor |
When the starter is turned on, the traction relay is repeatedly activated and disconnected | |
Low battery Breakage or short circuit in the holding winding of the traction relay of a starter A large voltage drop in the power circuit of the starter traction relay due to strong oxidation of the wire tips | Charge your battery Replace starter relay Check the wires and their connections in the circuit from the battery to the plug «50» starter |
When the starter is turned on, the armature rotates, the flywheel does not rotate | |
Starter freewheel slip Damaged starter gears | Replace starter clutch Replace damaged starter gears |
Starter noise during armature rotation | |
Excessive wear of the bearing shells of the armature shafts and the starter drive Loose starter or broken cover on drive side Damaged starter gears Damaged gear teeth or flywheel ring | Replace liners or covers and bearings with liners Tighten mounting nuts or replace starter Replace damaged starter gears Replace drive or flywheel |
Gear does not disengage from flywheel | |
Seizure of the clutch on the splines of the starter drive shaft Jamming of the armature of the traction relay of the starter | Clean the splines and lubricate them with engine oil Replace starter pull relay or clear jam |
