This is driving me crazy. My charging system is running at 15+ volts. It's a two field alt and I have gone through 4 VRs and still no difference. I have a ground wire for the VR as well as a new plug. The green wire to the VR from the alt has continuity as well as power with the key on.I have battery voltage at the main alt post plus batt voltage to the other (red)field terminal. I am using a volt meter and it pulsates as do the lights. What am I doing wrong that makes the alt put out such a high voltage?
