I have a 1999 F350 and I pull a 2004 Open Road Travel Trailer. On my trip this weekend, which was 3 hours one way, I blew this 20 amp fuse 3 times. I have not figured out a pattern as to when it blows. I was wandering if there was a known issue out there with this circuit. My trailer has 13 marker and clearance light and one license plate light. The bulbs in the marker/clearance lights are #194 and I think they draw about .3 amps each. So I shouldn't be having an issue. Again, are there any known issues with this circuit?
TIA,
Greg

Sounds like you have an intermittent short in your wiring. It would take a heck of a lot of lights to blow a 20 amp fuse. You probably have a wire rubbing on something and has worn through the insulsation.

Is this a new trailer for you or have you recently done some interior work? If so, check to see if maybe someone didn't put a screw, staple, or nail through a wire. I pull camper commerically and this is a common manufacturing problem. I have a auto-resetting ciccuit breaker switch installed on both running light and 12V power circuits on my truck. Fuses are expensive.
Hope this helps and good luck.

The trailer is about 2 years old and there hasn't been any recent construction. It doesn't blow the fuse every time it is connected to the truck, but the frequency has been increasing.
Did you replace the fuse with a circuit breaker or run a new circuit for the trailer lights with a circuit breaker?
Thanks,
Greg

My 4-wheeler trailer had a wire rub through and blew my park lamp fuse a few times recently. Didn't do it all the time. Drove me nuts. There was a sharp bend in the wire harness at the back that was factory. Took me a while to find it but it was near the rear taillights. I guess they never thought that trailers bump around a lot and wires could rub on sharp metal. [img]/ubbthreads/images/graemlins/shrug.gif[/img]
