Alternator will not charge

I first put on a used alternator that I know was good the last time I used it. Then I put on a new alternator, the exciter wire is hooked to the #2 tab on the alternator and the idiot light is hooked up. The charge wire goes directly to the battery. The charge wire has positive current verifying the battery connection is good, The exciter wire has positive power when the ignition is on, the idiot wire has negative power at all times. Now I know somewhere I am the idiot, but I just can't figure it out. This is a sbc in my Monza Drag car.

Just because it is new does not mean it works. First step is go get them both tested so you know where you stand.This is normally free so all it costs is your time and you won't be fighting the wrong problem.Let us know after test and we will try to help with next step.

Always remember this
Rebuilt means it has already broken at least once.
Brand New means it has never worked before.

Alternator

You were right, both alternators were bad. Got a new on and tested it before I left.
