Hey guys need some help BAD with a problem on a 66 t-bird.

Heres the problem.

The chargeing system was not chargeing the when i finished restoring the car at the end of last year so i figured it was an alt. problem so i'm getting the car ready for a show and for the woodward dream cruise right now so i just picked the alt. up from being rebuilt. The alt. was rebuilt and tested so it should be good,well after installing it today it is still not charging when its running.

I replaced the alt. the voltage reg,made sure the ground from the alt. was clean and grounded.

I have power from the main power wire going to the alt. and the power wire going to the voltage reg. but the problem is there is no power in the white field wire at all.

The electrical system of cars is one thing i admit i have NO clue as to what to do besides the basics so ANY help is very welcome.
I'm trying to get the car ready for a show this saterday and for the dream cruise in less than 2 weeks so anybody has any thought of what to try next let me know...i'm stummped!!!

thanks
BG
