Hi !
I have XJ 1989 4.0l limited and recently my alternator stopped working.
My friend gave me alternator from XJ 1992. Before installing it I had to exchange mounting bracket nad serpentine belt.
Now mechanicly is OK, but electrical connection is different.
In my old alternator I had connector - I cut it and two wires connected to small screws on the back of 1992 alternator.
It didnot charged.
Next I checked which wire has 12VDC and I put it to the alternator screw-PIN+, and another screw-PIN I connected directly to the ground.
It is charging, but I have 18 VDC on battery right now.
Hmm - The 1992 alternator does not have built-in voltage regulator - if not - where it is in the car - in ECU???
How I should connect it to right working?
Thanks
Pawel
