🔌 Function

The starter converts battery power into high cranking torque. When the start circuit energises the solenoid, the pinion engages the flywheel ring gear and turns the crankshaft until the engine starts, after which the overrunning clutch protects the starter from engine speed.

Common signs of failure:

• Solenoid clicks but the starter does not rotate

• Slow cranking with a fully charged, correctly sized battery

• Pinion spins without engaging the flywheel

• Grinding or repeated pinion kick-out during cranking

• Intermittent operation caused by worn brushes, solenoid contacts or heat soak

• Excessive current draw, overheating, burnt odour or corrosion damage

📦 Condition

• Brand-new aftermarket replacement starter motor

• New and unused

• Supplied in suitable manufacturer or equivalent protective packaging
