Good To Know

Q: How do I know my solenoid needs replacing? A: A single click with no crank, or intermittent starting, often points to a failing solenoid rather than the starter itself. Testing voltage at the solenoid terminals helps confirm the fault.

Q: Is this a genuine OEM part? A: This is an aftermarket replacement built to match the OEM 278003012 specification, not an original brand component. Confirm your model and serial number before ordering.

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