My '93 Jeep Cherokee is over charging. The gauge is correct and the ECM has been replaced. I have even replaced the alternator. I know Chrysler voltage regulators are in the computer so that's where I started. The alternator was original so I replaced it also. Any guesses? Thanks in Advance.

do you have a scanner tool?
If so you can do a field test
did you check for codes stored
check wiring between alternator and car module
