Fog Light Frustration with wiring

[Bob L]

Power out of relay goes to your lights not the Bat. Power into the relay goes to the bat.

I just spoke with my electrical engineering friend. I'm taking it all to his house. He said the same thing about the grounding. I'll post a final update later this week.

OK, so here'w what we have so far. The relay was not correctly wired and my main ground off the relay was weak. The ground for the lights and the switch were good. So, re wired the relay and established a better ground and it was great. While doing so, the inline fuse from the switch to the battery blew, and was replaced with a 30A fuse. All was well. I drive home, and turn them on in the driveway, and the fuse blows again. So something is not right in there. Back at it tomorrow! Never worked so hard for a pair of lights.

Please tell us your not using a 30 amp fuse in the bat to switch wire that should be a 3 or 5 amp and the bat to relay Should be a 20-30 amp fuse. You have a major short to blow a 30 amp fuse.

Yes thats it! I think its probably the ground for the lights themselves assuming everything is working correctly.

Well, it turned out once everything was connected, the switch needed to be wired opposite from its markings. The switch was not turning the power off but turning the power on to ground and blowing the in line fuse from the battery to the switch. So when I turned off the lights after testing them once I was in the car, the fuse blew. Anyway, they work now, 20A fuse there now working great.
