...1500 with 135000 miles on it? My battery gage needle in a second starts to move to right of center on the gage and then back down a little to the left of center then back up again a little to the right of center mark. This gos on for a while as I am Idling. When I start driving, after a few seconds the needle stops doing it but sometimes it don't stop. sometimes it stays to the right of center like It is supposed to. Also, when the needle is moving back and forth like above I can hear the motor go down just a little, and then right back up.
