"You need to test both the battery and rectifier. Volt meter the battery, which should be about 12.5-12.8 volts. Test the battery~ hook up the voltmeter to the battery and start the bike (on draw test). If the volts drop below 10.5 at startup the battery is bad. Test the rectifier~ hook up the voltmeter at the battery while the bike is running. Twist the throttle. The volts should fluctuate between 12.8 (idle) and 14.6 (3000 RPM). If the volts are over 14.6 or the volt range doesn't change then the rectifier is cooked."
