I have recently begun to blow the 10A headlight fuse when turning the key on. The bike has had the HID kit and sidecar headlamp for several years with no issues. Any theories?

Yes, just a theory. A wire to the headlight has been rubbing against the frame, or a support, and has finally worn through and is causing a short. Find the bare wire, wrap it with electrical tape, and adjust its placement or path so it can't rub.

I like your thinking. Great theory. I'll investigate.

Did you find the problem?

Yeah,

I think it's the HID ballast. I described it to the company's tech support and they agree.
I put a standard H4 bulb in and all is well until I get a new ballast.

Good information and thank you for posting. Glad you found the problem.
