ok. thanks. that is just the info I needed. been running pertronix points conversion so long I forgets how to troubleshoot points.

red test lead to - side of coil

black test lead to good ground

no, I did not know closing the gap increases dwell. seems I went the wrong way and it got better.

could be why I am at 25* with a wide gap?

I set points with a feeler gauge at .016 and ran it. now checking with a meter I am a little fused as in why I open the gap wide and it seemed to get better throttle response.

I will retest and see what I got now I am less fused.
