Voltage Regulator Issue / Fix - MUST READ!
Might be a good "sticky."
I just replaced my battery (VERY bad shape), voltage regulator, and stator. After all that I was showing 13.5 volts at about 1,200 RPM, but then any higher RPM would drop it down to 12.3. I contacted the person I bought the voltage regulator from and he mentioned that some first-gen V-Max owners have run a ground wire direct from the voltage regulator mount bolt to the frame or to the negative terminal on the battery. I did just that - I cleaned the regulator housing up for a good connection, then ran a wire direct to the negative battery post. I did notice a lot of corrosion on the frame piece the regulator is mounted to. It functions PERFECTLY now.
I would HIGHLY recommend you do the same!
