I have a 1992 Ultra Classic that I had triked. My question is concerning the regulator/rectifier and it possibly being bad. My in dash volt meter shows around 10 1/2 at idle, and about 13 when riding. When I use the turn signal or even hit the brake, the volt meter dips. When sitting at a light and it shows 10 1/2, most of the time the turn signal will not work. When it does work, the voltage goes down to below 10 volts. The book states the regulator should keep a constant voltage, which mine does not do. Am I correct assuming the regulator/rectifier is bad, or could the stator not be putting out the right A/C voltage for the rectifier to do what it needs to do properly?

 

Check all the battery cables to ensure they are tight first.

 

All cables and connections are tight, and the bike starts every time, telling me the battery is getting charged just fine.
