Use Guide
- Confirm the vehicle is a 24V system before fitting
- Match the 100A rating and connector pattern against the old relay before ordering
- Isolate the battery, unplug the failed relay from the control panel and fit the replacement in the same orientation
- Test the relay by turning the ignition switch on and verify the main battery circuit closes
- If the relay clicks but the system does not power up, check the battery terminal and earth connection before condemning the relay
