I thought this was resolved with a new battery but it's not. I believe it is electrical. The primary on the coils is .2 ohms high on each coil and the stator appears to be functioning normally except the DC charging voltage occasionally drops to below 10 momentarily before rising back up to normal. The r/r passes the diode test and the stator resistance readings are normal. Am I looking at the stator, r/r, or the coils as the likely culprit?
