Use Guide
- Confirm the truck is a 24V system before fitting
- Isolate the battery, unplug the failed relay from the relay panel and fit the replacement in the same orientation
- Test the starter circuit by turning the ignition key to the start position before releasing the vehicle
- If the engine does not crank, check the battery voltage, ignition switch signal, and starter motor earth before condemning the relay
