Default Re: battery gauge low then jumps back up then low again

Is the battery light coming on when the gauge is reading low?

Sudden drops from normal to low or sudden jumps from low to normal indicate whats most likely an alternator failing. If the light is on, this is for sure. If its not on, you could have a connector problem too but I'd still bank on the alternator.
