Re: Problem with charging battery

12.45v still seems a bit low but if the battery is already fully charged it may be OK. I would turn the lights and heater motor on and then check again. If it is still 12.45 at a fast idle I would say there may still be an issue. Almost all mfgs set the regulator to have the generator provide about 1 volt over the nominal resting battery voltage in order to keep it charged while the battery is supplying an average current draw.
