I need to know how many ac volts at 4 to 5 grand on the tack between the yellow leads comming out of the stator, trying to decide if I need to pull motor or just replace the reg/rectifier , charging at about 11-12 volts with known good battery. When I tested the the stator I got 54 volts between leads but shop is saying about 70 to 80 volts souunds to much to me. Thanks
