Just had the same problem. The voltage regulator wires had come loose. Remove the secondary clutch and check all of the voltage regulator wires. I found the plug on mine half connected. Soon as I plugged it in all the way the apv worked perfect again. If that looks good then check the wires near the servo and make sure they didnt rub on the secondary. If you are still having no luck then try swapping the ecu with a different one. If you are still stuck then the last resort and the most unpleasant is swapping the stator.

I had the same problem, I pulled my stator out and the lighting/power valve coil had a broken connection. You can test that coil without removing the stator with an ohmmeter. Look for a cable with two yellow wires and one brown wire near the flywheel. Pull the connector lose and make sure you read about 0.1 ohms between the two yellow wires going to the stator. If it reads a large resistance or as an open circuit, you need to look at your stator.
