Borrow, rent or buy a volt meter and test the battery voltage with the engine running. Have someone take the rpms up to about 1500 and test the battery voltage. If it's very much above 14 VDC, you have a faulty regulator. Ideal voltage is 13.5 but if it's anywhere near 17 or more it will destroy the battery. On the other hand, if one or more of the cells are shorted out, normal voltage will cause the remaining battery cells to boil.

Where is the external regulator for the alternator on a 77 dodge power wagon?
YOU MEAN THE VOLTAGE REGULATOR? The voltage regulator is basically a gatekeeper that will shut off the flow of juice to your battery if the voltage goes above a certain level, usually 14.5 volts. This keeps your battery from getting overcharged and cooked. They call it an external voltage regulator nowdays because newer alternators have them built into the alternator unit itself

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.
