Thread: Earth Issue for Driving Lights

I fitted a set of driving lights to my Puma Defender a couple of weeks ago using a Lightforce install kit and relay.

Everything worked very well until a couple of days ago. The lights stopped working.
After a poke around with a meter, I discovered that the screw I used in the engine bay to connect the lights and relay earth to no longer had continuity with the negative terminal of the battery. Everything else was as it should be.
