I used a yamaha test harness on the stator wires and found it was only 67- 70 volts.i dont know y it was different last week.i must have been doing something wrong.this stator is producing 165 volts on both circuits. Idles great-runs great.also found after that the isolator for the #2 battery wasnt allowing charge to it and it was overheating the connector on the regulator.i jumped the battery positives together for a test and the regulator cooled and batterys charged up.ill replace the regulator next.
