Where is the voltage regulator on a 1992 Chrysler lebaron?

The voltage regulator on a 1992 Chrysler LeBaron is integrated into the alternator. Unlike older vehicles where it was a separate component, Chrysler, and many other manufacturers by that time, had moved to a design where the voltage regulation circuitry is built directly into the alternator itself. Therefore, you won't find a separate voltage regulator to replace. If you're having charging problems, the alternator itself needs to be addressed.
