Hello, again, again Bridget. First I sent you explanation of the ignition system and I gave you my best guess---ignition module on your 1994 Plymouth with V6 3.4 L engine.
As far as voltage regulation goes there isn't any external devise to do this. This voltage voltage regulation take place inside the alternator after the three phase AC voltage is turn into none regulated DC voltage. Now this DC voltage goes thru a voltage regulator that built into the alternator where the output DC voltage is 13.8 to 14.1 DC Volts. Now, the alternator is regulated for current by the it wire windings in the alternator. Larger the copper wire the more current the alternator will produce. GB.....stewbison
The regulator is not built in, it's a component within the regulator that can be replaced. You will probably have trouble locating one at a parts house so your best bet is to bring it to a shop that specializes in rebuilding starters and alternators. Pulling the positive cable from the battery is not a reliable check. If the alternator is putting out 11.9 volts the car will continue to run but that is not enough voltage to keep the battery charged when under a load.The regulator is not built in, it's a component within the regulator that can be replaced.
