Default Light circuit burning out fuses ... WTF

Went to ride home from work this evening and got on it and started up ... about to take off when I thought ... hmmmm ... a little dark ...

Realized the headlight wasn't lit up ... thought maybe it was an issue with my the bulb or wire, but thought to check the fuse ... burnt out ...

So, pulled a spare and replaced the fuse ... turned the key ... same thing ...

Any thoughts ...?

You have a wire grounding out somewhere in the headlight circuit.

Or tail light I suppose ... although more likely head light ....

That's what I kind of surmised ... now I am really screwed ...

I am out in the middle of nowhere, it's too dark to be able to see to work on it and troubleshoot to find the ground ... and on top of that I'm out of 15 amp fuses, too ...

Default Light circuit blowing fuses

I had that problem on my 04 Ultra. The wiring fom the dimmer switch routes around the neck and turning the handle bars wore through the insulation. I got a roll of the plastic wire loom and slid that over the wires and havent had any more problems.

The diagnosis rule of thumb--always start with the last thing you changed.

SE 95" BB kit ...

Before that, Andrews TW37B Cams ...

But, got it figured out ... the headlight connector had some of the insulation worn off of one of the leads, and a bit of a kink in the wire right as it entered the connector (had to jam it in to get the lug to seat) ... seems maybe the exposed wire was touching the lug next to it ....

I think that was what it was ... put a shrink tube over the exposed lead and reinstalled it ... seems to have done the job ....

THX all ...!
