Re: Dash light bulbs keep buring out?
Exactly, if you have to much voltage that will cause this problem. You may have a voltage regulator that stuck. Do you have a volt meter? get one and check battery voltage with the engine running. You should have between 13.5 and 14 volts at idle. If you are seeing 15 + volts, then I would suspect a sticking voltage regulator. Do you have the correct amp fuse for the dash lights. I think they are only 5 amps if I remember.

If you check the voltage, and it seems good, it is likely a ground problem. When you have too low voltage, the bulbs will also burn out fast.
