Use Guide
- Confirm the vehicle is a 24V system before fitting
- Isolate the battery, unplug the failed relay from the control panel and fit the replacement in the same orientation
- Test the relay activation and deactivation under load before releasing the vehicle
- If the battery does not connect or disconnect properly, check the control signal and ground connection before condemning the relay
