Motorcycle tech help - 78\' KZ400 help! I cant find a motorcycle forum. Maybe somebody has a Kawasaki bike similar to mine. Its a 78' KZ400, and it has a charging problem. The battery slowly dies as the engine runs. I tested the rectifier and it seems to work. I also tested the output AC voltage from the stator and it was putting out about 60 volts or so. Am I forgetting to check something. Everything else is golden on this bike, I really want to get this bike going so any help would be grateful.
