Voltage Regulator Bypass
Heres what I did on mine. I used a 12v red LED light and drilled a #50 drill hole on the discharge side of the ammeter. I also converted the ammeter to volts. The indicator light gets its power via ignition switch. The contactor for it is in the alternator. When you rotate the key on, the contactor for the light closes to ground to illuminate it. On startup when the alternator starts working the indicator light contactor opens and the light goes out. If the alternator goes offline, the indicator light closes to ground and the light goes on. I used a small enough hole, and a red 12V led that's JB welded in. You can see it's getting its power off the volt gage 12V feed
