Update.....changed out the regulator. Voltage is right where it should be at idle and 3500 rpms. Speedo now works perfect. Tach still does not. I checked power at the tach and I have 12.3 volts on the orange, which I assume is the light on the tach and runs off the ignition module. The pink shows about 5.5 volts when engine is running and the black shows .01. Does that mean im losing my circuit somewhere in the tachometer?
