I have a 2002 Drz 400. I have been having an issue with my charging system, so I unplugged the wire from the stator to the rectifier and tested the voltage from each wire while the bike was running. 2 of them tested around 40-50 volts and the other one didn't get up past 20 volts. Bad stator correct? I then ordered a 20% stronger.high output stator from racetech electric on ebay. Now that i have the new stator installed the battery is showing over 16 volts at idle. Is this too high or is this because it's a high output stator? I have read a little bit in other forums about testing some grounds.
