A charging system test is done to check the internal voltage regulator. It can be done at any auto parts place.
To get to an internal voltage regulator first disconnect the battery ground ( negative cable ) then remove the alternator. Make sure you mark the cables on the alternator so you can put them back exactly where they are supposed to go. The voltage regulator is inside the alternator and you will have to take it apart. I'm not sure how the regulator is mounted in your alternator, it might have small studs with nuts on them, or small screws or bolts, or it may be soldered in. In the latter case you will have to cut out the voltage regulator and solder in the new one. If you are going to take out the alternator anyway you should probably take it to a parts store where they will test it for free and tell you if you need a whole new alternator or just the voltage regulator.
Check on the firewall near the coil. the voltage regulator is internal with the ecu for this model truck...if you, like me, have had yours go bad (internally) you can optionally use an external regulator from your parts store, just ask them if they carry a vr32 or a vr1...both of which should work
Regulator is mounted on the back of alternator. It is replaceable if you can find parts. Brushes are there also.
A voltage regulator is just as it says. It regulates the voltage that the alternator in your vehicle puts out. Too much voltage and you'll overamp your wiring, and too little can cause parts not to function properly.

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 voltage regulator is defective. It may be internal or external to the alternator. Any auto parts store can provide this information. Have them check the alternator for output.
The main caused of component failure especially electronic part is power surging or spikes to best protect the parts is to install a good power surge protector.
your local parts store or a junkyard
Its is normally located on the back of the Alternator...See your Auto Parts store for a replacement...
The regulator is internal to the alternator! Just replace the alt. The alternator has an internal regulator that can be replaced by itself; however, when there is an issue with the alternator, it often involves diodes in alternator instead of or in addition to the regulator. better repair shops will often take an alternator to an automotive electrical repair shop for same-day rebuilds, with the value much higher than a cheap rebuild in a chain parts shop, and hundreds less than a dealer replacement. You want Bosch or your own Bosch rebuilt
