|---|---|
| Universal 12V starter relay | universal relays require rewiring and risk incorrect pin assignment |
| Used or reclaimed relays | New units carry a 12 month warranty from B/L date; reclaimed stock carries no warranty and may have degraded contacts |
Use Guide
- Confirm the truck is a 12V system before fitting
- Isolate the battery, unplug the failed relay from the engine bay relay block, and fit the replacement in the same orientation
- Test the starter engagement and release function before releasing the vehicle
- If the starter continues to crank after release, check the ignition switch and relay ground before condemning the part
