I took a trip up to WI to pick up a horse a couple weeks ago, and 2 hours into the trip I stopped to get some breakfast and left my truck running while I ran inside... all the lights on the trailer were working fine, when I came back out of the restraunt the running lights on my trailer were off. I tried messing around with my plug, and even tried plugging it into the bumper. I had to wait around for about 30 minutes before it would get light out enough for me to proceed w/o trailer lights. The turn signals, brake lights, brakes, everything else is working fine, just the running lights. Now I thought it was something in the trailer because there has been problems with the electric on this trailer before. So I just got a call saying the lights are working fine on my g/fs moms truck. So it must be something on my truck... does anyone know if there is a fuse that controls the running lights? By any chance do you know what number it is?

Thanks for any help. I hope it's just a simple fix like a fuse...

If the '05's is like the '03's check fuse #33.

Thanks a lot. does it sound like a fuse problem?

 

Could be. The trailer brake and turn signals have separate fuses.

Go ahead and replace the fuse (my 03 is number 33 also), but remember, something happened to cause the fuse to blow in the first place. The trailer may have a wire somewhere that shorts out intermittently, or a faulty light fixture, ect. That is a problem that can be a lot of fun to track down.

HEY, when my 05 was brand spankin new it did that with my trailer that a Ferd had been draggin for years with NO PROB... the fuses were just too weak ...I put stronger fuses in and NEVER had another prob

ALSO when you open the fuse panel flip the cover over....its all there in SIMPLE english

 

PS ... my Bull trailer has 16 clearance marker lights 2 bulbs each(big draw)

 

Thanks, I still have yet to go out there. Was your 05 fuse #33 also? Oh and before I open it up and find out I need to run up to the parts store, what size fuse is it? Thanks
