Do you mean when you unplug the 2-pin plastic connector, or when you unscrew the terminal lug nut on the back of the alternator, when the draw goes to 0?

Are you testing for draw with the key off?

Does terminal 2 of the 2-pin plastic connector lead to the existing junction (solder by factory) by the headlight?

Does terminal 1 of the 2-pin plastic connector lead to the brown wire that goes to the cab firewall connector?

If you think things are wired OK, I believe most car parts stores will test the alternator for you.
