F350
Guys,
Not much help on any truck sites so I thought I would try here...anyone have or know how the trailer circuit is wires on a 2002 F350? I thought my trailer was screwed but did some trouble-shooting and found it was the truck!
Running lights work...0.9 V on lft/rt stop/turn signals with no brake pedal. 1.3V with pedal applied???!!!!
I have traced the wires all the way back to the fire wall and no shorts/grounded wires. I checked the fuse, was OK. I have 12V on the "hot" side in the fuse box. Doesn't show continuity to ground on the "downstream" side of the fuse????
Thanks

Re: F350
I have a 1999 and I had a problem with the left trailer light.I found that in addition to the fuses located in the cab on the left bottom of the dash down by your knee,there are seperate fuses in the breaker box under the hood that is on the right side towards the back.It holds all the Breakers for the computer stuff but also has all your trailer light fuses.-
