Thanks Doughboy..

Im working with 3- 2/0's and the grounds will be short from the Alt ground stud to the alt bracket..which with the fluke tests a good ground...they all will be going to a common point. I do want to put 1 large 2/0 ground from the engine block to the frame .This big diameter wire can be a pain.. good thing its that welding wire and very flexible.
I looked under the field plate..looks like the long studs have the brush spring around the screw.. Man im in an area ive never been im hoping i dont have a mistake somewhere and burn up an Altrernator..these leeces arent cheap as you know.
