Anything is possible in regards to the Regulator being still installed. The regulator is on the Relay board in the Engine compartment. It is a Square looking box about 2 inches tall about 1 1/2 wide 3 inches long.

You said you tested the Altenator out of the car and it tested good. But how does it test when running in the car I assume it is not charging ?

You need to trace the wiring and connections in order to trouble shoot this. No easy answers.... Also check the Ground strap at the back of the Transmission. Make sure that is connected.

There are also some tech articles on this Board for Altenator trouble shooting as well as doing a search on previous posts
to help you with your problem.

Good Luck
