It was showing 12.7 volts running without the lights on. Voltage dropped to under 11 with lights on. Replaced the rectifier and the voltage is lower. Reinstalled the old rectifier and the voltage is the same as the new one, lower than when it was on first. The battery is new but I'm thinking it may be bad. Does anyone have the procedure and specs to test the stator on this model? Could the charging system be good and the battery just isn't taking the charge? Any ideas would be welcomed. Thanks.

Checked the battery today and it had a bad cell. Installed new battery and everything seems fine. Rectifier was bad and ruined first battery. It was ran at night and completely drained battery.
