Trailer lights..96 Fatboy
I have a 1996 Fat boy that I put a trailer hitch on and wired myself. I have checked and rechecked my wiring and everything looks good and works. The problem I have is that the lights on the bike cancel out and then turn back on. I am guessing there is a circuit that has a fuse because I will be going and all of a sudden I dont have any lights..30-40 seconds later they come back on! It really freaks the wife out...anyway, I was wondering if anyone has done this and if I need to put a different fuse in or do I have something backwards????thanks for any help

Electrical circuits can get a little tricky. If you just tapped into the existing light circuit Chief is probably right and you did overload or overstress something in the circuit.
Try changing out the fuse or circuit breaker first, its very possible that its not blown, but cracked. When that happens it will work and not work as it heats and cools.
The best way to get a trailer light setup on a bike, or car for that matter, is not to tap the existing circuits for the lights power. But install a relay box so that the vehicles turn signals and brakes only 'trigger' the relays. That way the trailer lights get their operating power off the towing vehicles main/battery power line without overloading the turn or brake circuits.
