Good To Know

Q: How do I know my solenoid needs replacing? A: A single loud click with no cranking, or intermittent starting, often points to worn solenoid contacts. Testing voltage at the starter terminal while pressing start helps confirm the fault.

Q: Do I need to disconnect the battery before installing it? A: Yes, always disconnect the negative battery cable before servicing the starter circuit. This protects you and the electrical components from accidental shorts.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
