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.
The engine computer is the voltage regulator.
The voltage regulator is on the alternator. It is on the rear, within the alternator case.
Inside the rear of the alternator no it is not, it is in the powertrain control module The engine computer is also the regulator.
The voltage regulator for the alternator is in the computer. If the voltage regulator in the computer does not work, you can add an external voltage regulator and then your battery will charge normally. Make sure to check the ground on the computer. If the ground is bad on the computer, then the computer will not regulate the voltage to the alternator properly.

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.
It does not have one that is external. The voltage regulator is built into the alternator.
