so just to clarify, this alt was used 10 plus years ago on the car when it had the old style regulator, after removing the alt this evening and having a better look at it the field terminal where the green wire goes has no plastic washer under the screw, the terminal where the blue wire goes does have the plastic washer.. so the field terminal with out the plastic washer is grounded to work with the pre 1970 regulator, make sence? that was my over sight, however the other field terminal with the plastic washer still has continuity to the alt case its self,

with the car running when i would go to plug the blue wire in it would spark you would hear the idle drop slightly and it would be charging ar 15 volts up to 18 off idle. i decided to try plugging the blue wire onto the other field terminal and it instantly shut the car off..
