Hi,posting for a friend,he has a 94 Jeep Wrangler-Sahara Edition.with the 4.0.
Can anyone tell me where the voltage regulator is on this thing? Inside the alternator or inside the computer?
On my 92 Cherokee with the 4.0 it is inside the computer.had a alternator rebuild place install a voltage regulator inside my alternator,works great but my check engine light stays on all the time now,has been for the last 5 years.He has emissions testing,so he cannot have a light on.
He called the big auto-parts stores and was told it was inside his alternator.Is this TRUE? they quoted him $115.00.
I just don't want to see him going through all the trouble replacing his alternator if indeed it is inside his computer.He does have a CEL on now.tryed having him give me the codes over the phone,didn't work out that well.
Any help? Thanks for your time.
