If it has gone bad, you should probably replace it. However, if you want to attempt the repair, it would depend on what is wrong with it. Like an electric motor, a voltage regulator commonly has brushes which wear down over time. Perhaps these brushes have worn to the point that they need to be replaced. If this is the case, I recommend changing them at a small repair shop that does that sort of work. Ask around with local handymen or guys at the autoparts store. Someone does it and it will probably cost $20. I don't know if you can buy the brushes to change yourself. You could also replace the voltage regulator by finding one at a junk yard.

Where is the voltage regulator on a 1998 dodge ram 1500?

Found the answer: The voltage regulator on a 98 Dodge RAM 1500 is NOT in the alternator. The alternator specifically states that the voltage is "Externally Regulated". In this vehicle the voltage regulator is built into the computer of the vehicle. To repair a bad voltage regulator in the computer you can either replace the computer or bypass the computer using about $50 in parts (ask your mechanic). Hope this helps.
