When helping a friend trying to tow a school trailer, i hooked up to this trailer that had a few electrical issues. To make a long story short, it blew several fuses. I looked in my manuel and saw that there was a right stop/turn and a left stop/turn. I checked these both and they were both blown so i replaced them. However i did not see a fuse for tail lights only a relay. Do i have to replace the relay to get these lights working again. Right now i can only take my utility trailer out during the day because i have no running lights. Can someone give me any info. Thanks

do your truck's parking lights work? If so, do they work with/without the trailer?

 

There is a trailer running light fuse.

I've had it burn out on me.

 

geno87-69,

Do you remember which fuse it was by any chance. Looking at the owners guide the only one that i could see it being is #10 or #37, but i guess i can pull a few fuses when i get home tonight. I still have a crick in my neck just changing the one's i did yesterday.

inbred,

all my lights work on the truck, it is just when i hook my trailer up to the truck that the trailer lights do not work.




Thanks guys,
Brian

 

The problem isn't with the truck, it's with the wiring on the trailer. The cheap trailer kit lights are real bad on the bass connection to the bulbs and grounding. If you have a mutimeter, I would check for a ground to the trailer frame and the wiring going to ground. If that checks ok (meaning it shows 0pen ohms), I would open each light and clear the bulb connections and check the bulb. If it shows a ground, you'll have to find the wire causing the problem and repair/replace it. Make sure the ground wire on the truck connection and the trailer connection are going to a ground on the truck frame or trailer frame.

Check the brake light volt out on the truck plug. Have someone push on the brake paddle while you check to volts on the plug. You should see 12 volts each time they press on the brakes.

 

I can relate.

I had to change mine in the rest stop on I-75, just before going into Ohio. It was in the dark, I had no "mini" fuse spares, it was 11:00PM. Luckily the same fuse was used in the horn, so I pulled the horn fuse, and finished my trip to get my SVO.

Haven't had another problem.
Unfortunately I can't remember which fuse it was.

 

Out of curiousity...did you plug the trailer in w/ the engine still on and/or the headlights on? It's a common problem...

 

No.

It had been plugged in for a day. We drove from my house in Mandeville, straight through to my parents house in Ohio.

The lights were working in Knoxvillle when we stopped for dinner, then I looked back in my mirrors, and the running lights had gone out.

It was weird. Only happened that one time, but now I have a ton of spare fuses.
