Use Guide
- Confirm the vehicle is a 24V system before fitting
- Isolate the battery, unplug the failed relay from the preheating control panel and fit the replacement in the same orientation
- Test the preheating cycle and glow plug activation before releasing the vehicle
- If the preheating system does not activate, check the glow plugs, fuse and earth connection before condemning the relay
