Common faults of automobile starters: 1. Improper adjustment of the starting switch or solenoid switch stroke; 2. Improper adjustment of the gap between the fixed and movable contacts of the armature moving type; 3. Excessive wear or slipping of the starter drive pinion or flywheel gear teeth; 4. Loose starter fixing bolts or clutch housing; 5. Internal fault of the starter. The causes of starter idling faults are: 1. The shift fork of the mechanical forced starter is disengaged and cannot push the drive pinion, or its stroke is improperly adjusted and cannot engage; 2. The stroke of the solenoid switch core of the electromagnetic control starter is too short; 3. The auxiliary coil of the armature moving starter is short-circuited or open-circuited and cannot bring the armature to the working position; 4. The starter one-way clutch slips. The causes of weak starter rotation are: 1. Insufficient battery power or loose connection wires, poor contact; 2. Starting switch contacts are burnt or solenoid switch coils are short-circuited.
