1993 Jeep Cherokee Charging System

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.[/quote:326d12fc9a]

just a suggestion did you check the battery

I have replaced the battery three times now. I should have mentioned that before. Sorry.

It is between 15.63 and 16.95 at the battery. I appreciate your help.

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
