Where is the voltage regulator on a 1991 Jeep Cherokee?
The voltage regulator on a 1991 Jeep Cherokee is integrated into the alternator. Unlike older vehicles where it was a separate component, Jeep (and most manufacturers) moved to this design by the early 1990s. You won't find a separate voltage regulator to replace. If you're having charging problems, the alternator itself needs to be tested or replaced.
