Blowing Fuses

Sounds like a bare hot wire on the trailer's wiring harness that's
occasionally shorting against the frame, or against a ground wire. Hard to
troubleshoot. A new trailer wiring harness is pretty cheap and fairly easy
to replace.

I have a 1998 GMC Sierra pickup 4x4 350 Vortec, and I keep blowing a
fuse when I tow my boat, it's the number 15 that controls the das and it
also runs the trailer lights. Anyone ever had this problem before? if so
how can I troubleshoot it.

I checked for bare or pinched wires and found nothing, replaced the wire
connections on trailer. It worked fine and then blew after I drove about
two miles. Could something be getting hot and causing it to blow? I
thought one day I smelled burning wire.

do you ever suberge your trailer and boat in salt water witch i in fla
always go back and forth i havnt found a way to save lights yet
but Cabella says they do all i know is to dunk trailer and
boat in fresh water and always flush moter.
