02 classic loses all electrical power randomly while riding
I'm going to give you a solution based on personal experience.
I have a 1971 FLH, 1200cc. 16" front wheel, wide glide front end. One main breaker, for all power leading from the main switch on the dash.
I would ride for exactly 8 miles, and the bike would cut off.
Nothing. Nada. Just pull over to the side of the road, and let the circuit breaker cool off. (About the length of one cigarette) Then I'm on my way again for 8 miles.
Tore the seat off, rear wheel out, dash off, headlight nacelle apart, and started checking all wiring.
Found a few breaks in some of the insulation of the wires, found where someone used tape instead of heat shrink tubing. Fixed it. Tried riding again, same thing.
Went through a few more procedures. (I am a Harley mechanic on the older ones)
Finally one day I took the headlight out again, and looked for a short. (I had narrowed it down to something to do with the headlight)
Didn't see anything apparent again. Noticed this time though, that the plastic connector to the headlight, was open on the back.
All three terminals of the headlight, that went into that plastic socket, were exposed at the back.
Having just worked on my Chevy truck, I remembered that the plastic headlight socket, is Enclosed on the back.
Went back to my bike, looked REAL close with a flashlight, and saw a 1/8th inch black mark on the triple tree. The headlight terminals are too far away to create a short?
Removed the plastic headlight socket out of my truck, put it on the Harley.
Has Never quit on me since!
[Hey, we're talking my Harley to a truck! I did get another headlight socket for the truck later!]
