Troubleshooting Trailer Running Light Circuit Fuse that Has No Voltage


am not finding any juice at the trailer running light fuse.i have brake and turn signals but no running lights.


Expert Reply:

If the fuse of your trailer running light circuit does not have power running to it then that would indicate that there is a bad relay associated with that circuit. If you check the diagram for the fuses/relays on your vehicle's fuse box there should be a section that has the relays listed and the associated circuits.

The easiest way to test a relay for being bad is to replace it with a known working relay. If it works at that point then you know it was the relay.
