FYI - Intermittent elec kill & fix.
Just in case one of you runs into this with an Evo dresser....
Symptom:
I'd ride off somewhere and go to restart the bike (1996 FLHTC) and the bike would turn over, fire, then half the dash would die and the motor with it. That got more frequent as time went on until it did it at a Harley Drags weekend.
The fix:
I took the outer fairing skin off and noticed a relay off the main power wires (fat red ones) located by the radio speaker on the right when looking at the bike from the front. I pulled the relay off the harness and noticed blue powdery corrosion completing an electrical path between the posts. Scraped it off and solved the problem.
The sermon:
Always carry tools and know where they are. Grab your torx-bits and pull that outer fairing and look at the wiring once in a while. I hadn't done this in the year I owned the bike, but it was probably a good thing to remove the mouse nest I found when I did. It doesn't take long to do it. 3 fasteners along the windshield, 2 on the outside low and 2 inside off the fork legs behind the headlight level. Better to do it in your driveway than at a rally with a hangover after you slept one off on the concrete.... 8) Start to finish the investigation and repair took 20min.
Maybe this helps, maybe this doesn't.

I didn't have the manual with me, but I have it at home so I'll crack that sucker, look at the schematic and try to ID the part for everyone. What's a DPO?

OK, on page 8-159 in the ol' manual, there is a starter relay that looks like where I found the relay I cleaned. Don't know if that does anything once you let off the starter button, but there ya go.....

Alright, here's a shot of page 8-159 of the shop manual for FLT models. The relay in question is the starter relay labelled in the lower right.
