Ok so I'm hooked up to my buddys goose. Went to the car wash to spray it off since I got mud, dirt, and gravel on it. Pulled up everything was fine all lights and brakes worked. Shut my lights off because they were pointed at some apartments. Sprayed off trailer, spraying back towards truck to, get done turn lights on and no running lights!
Brake lights, turn signals, NO running lights?
Only thing that's weird that I can find is the brown wire is pierced like it had a scotch-lok on it, but I can't find where it would have attached to any other wire?
I even unhooked from the goose to see if water was in the neck/on the ball. Dry as a bone?
Took it back to Anna's and dropped it since it was 9PM, and my buddies house was 20 miles away.
Any idea where to look?
