Parking lamp gremlin

[curtmush]

I'm stumped guys. 93 Chevy and keep popping the parking lamp/horn fuse. Back story to when my problems started. Pulled a camper 4 hours. Everything worked great. Arrived at my destination, unhooked and parked the truck. Moved it about an hour later and it popped. So far I've checked turn signals with the light switch on and off and brakes. All bulbs are good. Headlights work (different fuse, I know). I tried a 25A fuse, popped that after a 10 minute delay or so. So before I cause more damage, here lies my confusion. Is it a short in the wiring or the headlight switch bad? I checked the switch and didn't see any damage. Only addition light I have on the truck is a Autometer trans temp gauge. Thanks for any advise.

I'd be checking your trailer wiring harness. Sounds to me like something might have been damaged when you last used it. It tees into the brake/turn signal wiring so if there's something shorted there it would definitely cause issues.

I bought one of those connectors that tees directly into the wiring harness at the box connector. I soldered and shrink wrapped those connections to the new trailer plug connector on the truck. I'll try unplugging it. Check it out. See what I find. Thanks for a start.

No problem, sounds like a plan. Let us know what you find out.

Problem solved. Um. Lets just say, note to self, do not to finish a wiring project in the dark again. Bare wire I forgot to tape off that was grounding against a bolt head. Oops! So far no popped fuses!
