🔌 Function

The heavy-duty starter supplies the high cranking torque required by large high-compression Volvo Penta diesels. Its solenoid engages the drive and switches battery current to the motor during starting.

Common signs of failure:

• Slow cranking despite correctly sized batteries and cables

• Solenoid engagement without starter rotation

• High current draw or excessive cable heating

• Pinion grinding, non-engagement or delayed disengagement

• Intermittent operation caused by worn brushes or contact discs

• Water ingress, field-winding damage or excessive shaft/bearing wear

📦 Condition

• Brand-new aftermarket replacement starter motor

• New and unused

• Supplied in suitable manufacturer or equivalent protective packaging
