🔌 Function

The starter motor engages the engine flywheel ring gear and rotates the crankshaft fast enough for the engine to fire and run under its own power. It draws high current from the battery bank through the starting circuit for the duration of the cranking cycle.

⚠️ Common Signs of Failure

• Engine cranks slowly or not at all despite healthy, fully charged batteries
• Audible click from the solenoid with no rotation of the engine
• Grinding or harsh meshing noise indicating worn pinion or ring gear engagement
• Starter continues to spin or fails to disengage after the engine fires
• Intermittent no-start conditions, burning smell, or scorched terminals and cabling at the starter

🛠️ Service Notes

• Disconnect the batteries before touching starter cables, and label the main and control connections as they come off
• Inspect the ring gear teeth before fitting a new motor; a chipped or worn ring gear will ruin the new pinion
• Mount the motor square on clean faces with whatever shims the installation uses, so pinion engagement matches what the workshop manual for your engine specifies — never leave shims out to make it fit
• Clean the main and earth terminals back to bright metal, tighten to the specified figure and refit the insulating boots; a great many failed starters are really voltage drop in the cables and earth path
• Crank with the engine unable to start first, listening for clean engagement and release, then feel the terminals for heat after several attempts
