    Hi please can anyone advice, my trx 420 has two regulators/rectifiers the larger rectifier checks out ok but gets warm. Stator resistance measures 12 to 13 ohms on each phase should be .1 to 1.0 ohms don't know why. AC voltage from stator is very high around 150v ac on each phase. Not sure how...
