Look at the wires under the back fender to start with. Also sometimes the bulb socket will short out , check that too . :)

Unplug the connector for the rear lights under the seat. The connector that goes into the rear fender. Using a powered test light or multimeter test each pin in the fender harness connector to ground. The grounded wire/wires will be the cause for the blown fuse.

Yeah... Unplug the rear fender and turn the bike on. If the fuse blows again you will know the fault is before that connector and if it doesn't blow then you the know that fault is after the connector. Use a wiring diagram to find where each wire goes and what it is supposed to carry. i.e. 12 VDC or if it is a ground wire. If something doesn't add up (by using a multi-meter) then there is more than likely your problem.

Did this problem just crop up all of a sudden ? No changes or modifications done to the bike prior to the problem ? Does the light system have a modulater or anything to change the light functions ?

I kept blowing a fuse killing the rear lights but I think it was all rear lights while on a road trip. Big Moose H-D traced it to a short in the wire harness inside the fairing...

That's why you should disconnect the rear light connector under the seat, to localize the problem. If the problem is still there with the rear lights disconnected then the problem is up front, if the problem goes away the problem is at the rear. That narrows the search down.

Found it!!!!!
Un plugged harness to the rear lights. Fuse still blown. Opened fairing disconnected from light bar still nothing checked front fender light nothing. Went to the trunk. Took it apart and found one wire inside the trunk with a small rub mark. That was the culprit. Last year I added a deal to move the trunk forward and back ward must not have got wires tucked away. Fixed now
Thanks guys between the forum and the service manual it made the project simple.
One more question. Any suggestions on a battery???

Yes I would definitely suggest a battery, very hard to get started without one.:rofl: Seriously just go to the search tab, there are hundreds of threads on batteries.
