Re: Battery Is Over Charging

Sounds like a regulator problem. Check the voltage going into the bike at about 2500 rpm with a voltmeter. It should be about 13.8 to 14.8 volts. Any more than that and you will cook the battery.

Re: Battery Is Over Charging

I agree here with the regulator, check at the battery with a meter to see what voltage you are getting there. Anything much over 14.5 , replace the regulator and clean up the mounting points where it mounts for a good ground.
