Good To Know

Q: What are the signs of a failing starter solenoid? A: A single loud click with no cranking, intermittent starting, or no response at all when the key is turned often point to a bad solenoid. Testing voltage at the solenoid terminals confirms the diagnosis.

Q: Is this solenoid a direct replacement? A: It is designed to match the factory mounting and terminal arrangement on the HPDI 300. Verify your engine year and wiring layout 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.
