Voltage drop at idle? More help needed!
For months I've had strange problems, I first had my battery light come on while riding, headlights dim, gauges go haywire, but I jiggle the ignition or turn it off/on it will return to normal. I've also noticed my voltage is good while riding 14 on the dummy gauge, but at a long light its starts to drop to as low as 7. Both problems seem to have the bike running off of the battery only.
Last night I put a battery tender on for a full charge of 12.8 this morning, I started the bike it dropped to 10.8 so the battery seems in good order. I also checked the stator for continuity and all was well, then I fired the bike and got 20.5 volts out of each phase at a cold idle or about 1100 rpms. I check battery to frame grounds, all good.
I think it's the voltage regulator, how do you feel about this and did I miss anything?
