marker lights burn out the fuse
I replaced all my old marker lights with new LED marker lights. Everything worked perfect for a couple trips, but something changed during the last trip (not sure what happened). When the camper is plugged into the truck, the 15A fuse burns out now. The lights don't flicker or come on at all and it takes about 30 seconds for the fuse to heat up and burn out. I'm getting 12.5 volts at the fuse from the truck. I assume one of the lights has a short or there's an exposed wire shorting.
What's the best process to diagnose the problem? Buy a box of fuses and disconnect 1 light at a time until I find the problem?
Thanks for the help.
