Good To Know

Q: How do I know if my solenoid is failing? A: A single loud click with no crank, or no click at all, often points to a failed starter solenoid rather than the starter itself. Confirm battery voltage first, then test the relay terminals.

Q: Is this a direct fit for the listed part number? A: It is built to cross-reference part number 278003012, so it matches the original connections and mounting points. Always compare your existing unit to the listing photos 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.
