I almost thought I had a loose connection, but then it leveled out....at 18.7-19.2 volts when riding.

When I stopped at a light and kicked it into neutral, it went down to 13.1 to 14.3 volts. This fluctuated, but never went above 14.3 when idling in neutral.

As soon as I'd take off and hit 3rd gear, 18-19 volts. Anything over 18.5 volts and I'd get the crazy RPM gauge when revving the engine. At 18-18.4v, the bike rides ok, but sounds "off".

Gonna try it again tonight and see if the voltage spikes correspond to when my lights brighten. I'm assuming they do.

Does this mean I have a bad R/R? I'm also going to assume here; I probably need a new one.
without re-reading the whole thread....check out ALL your electrical connections....Remove & Clean ALL grounds....check connector at R/R....Clean Contacts ! 18-19 volts can/will fry your electronics / battery !
... have you checked the Stator AC voltage output ?



EDIT: Did I mention Remove and CLEAN ALL Grounds ? LOL
