You should have BAT volatge at the BAT terminal on the VR. If so the next thing to do is jump the F terminal on the gen to ground. This should make the GEN go to full field and charge 100%. If it does you have a VR/wiring problem. If it doesnt then you have a gen problem

After you short the F to ground and if it still doesn't work, pull the belt off, disconnect the F wire from the gen, and apply battery voltage to the A terminal. The gen should spin fast like a motor. While motoring, ground the F terminal. It should slow down but continue to motor. If it passes these tests, load test your wires. If they all pass, your regulator is faulty.
