What Are the Common Issues with Car Starters?

[DiSebastian]

Common issues with car starters include: 1. When the starter switch is engaged, the starter makes a knocking sound but fails to turn the engine; 2. The starter spins freely but has difficulty engaging the engine; 3. Only a clicking sound is heard without the engine starting. Reasons for starter free-spinning include: 1. Slippage in the starter's one-way clutch; 2. The shift fork in mechanically engaged starters disengages and fails to push the drive pinion; 3. Improper adjustment of the stroke preventing engagement; 4. The solenoid plunger in electromagnetic control starters has too short a stroke; 5. Short circuit or open circuit in the auxiliary coil of moving-armature starters, preventing the armature from reaching the working position.
