How do you tell if a voltage regulator is bad on a 1998 Dodge Ram 1500?

The voltage regulator is responsible for regulating alternator output. Look at the volt gauge in the dash. If it is too high generally that means that the regulator is bad. Take the truck to Autozone and have them check it for you. They offer this service free of charge and will do it on the truck.
