Ok. I am having the problem with the headlight icon staying on my display, and getting the flashing red warning on my '83 Venture.
I started out with the headlight, and the battery flashing, because I just put a new battery on, and the terrible whine in my speedometer. I did the 1k ohm resistor fix, and took care of the battery icon...great fix, thanks.
I also removed the instrument panel and greased the speedo bushing with white lithium grease...works great...thanks.
I then resoldered all of the connections for the big white connector, plus a few more cold joints that I found.
After all of that, the only problem I still have, is the headlight icon, and flashing red light. All of my lights work fine.
Any more Ideas, before I get out the schematic, and pick the bike apart wire by wire?
