my battery light stays on.all charging and battery voltages are good.all fuses are good,the mega fuse is good..
Check altinator output for amps. It may not be putting out enough amps
The light still is indicating a problem with either the battery or the alternator. Make sure the battery is checked to make sure it is good. If you have a digital multi meter, a full battery charge would be 12.7 DCV. The alternator when the vehicle is running should be putting out anywhere from 13.8 to no more than 14.7 DCV. If it is then the alternator is over charging and the problem would lie with the voltage regulator.
