I have a Super M . The amp gauge seems to work well at lower RPM but really jumps around when the throttle is applied. It does seem to be charging. It has a new voltage regulator and the wiring is good. At an very low idle it will go to the negative side but just a little RPM and it will go to the charge side until more speed is added, then it starts it’s dance all over the place. I did check the ground on the cover box where the gauge is mounted. I did open the voltage regulator and noticed the points sparking when the gauge is jumping. They seem to hold tight at lower speeds.
Any ideas???
