I've done quite a bit of searching around the forum and found lots of posts related to this particular fuse blowing, but haven't found my issue referenced.
The tail and dash lights function just fine with the stock-sized 10-amp fuse. In addition to that, I can hook up regular utility trailers and pull them with the lights on without any problems. But, when I hook up an enclosed trailer the fuse blows after a few minutes with the lights on and I lose my dash & tail lights. I can get by without incident if I swap in a 15-amp fuse, but don't like to go up on fuse sizes.
I've pulled three standard open utility trailers, lights on, without a problem, but I've had the fuse blow with two different enclosed trailers (in between the utility trailer pulls). This leads me to believe it's not a short, but rather just a weak circuit that can't handle the additional lights installed on a typical enclosed trailer.
Does anyone have any thoughts on this, or has anyone had a similar experience?
