Key off it not important. Switch off is because it isolates the coil from the rest of the ignition circuit.

Chances are that you twisted something in playing with the points so that the points circuit is grounding out..

I agree with isolating the coil because I was just trying to isolate the continuity. I guess there is a chance that I shorted out the points. They are kind of old and I ordered some new ones today from eHarkleypart.com. They had some in the original bag.

All it takes is a small smudge of grease to short the points out. I always make sure my hands are clean and wipe down/clean points and plate after touching this area. In school we would f*ck with each other by using a soft lead pencil to draw a 'lead' line on the points to short them out. Then stand back and see how long it took the other guy to figure it out. They did it to me twice before I figured it out.

I did take that precaution. I took some 600 grit and pulled it between the contacts to clean off whatever junk got caught between there. My points are a few years old so i''m getting some new ones. Thanks

After you use the 600, you need to pull a piece of heavy paper or non glossy business card between the contacts to clean the grit..

Is the wire on the correct side of the insulator? I've seen people do that wrong. Or is it grounded somewhere? I'd be looking at that, maybe where it goes thru the case?

I had to run a new wire because it was worn and grounding against the case hole. I replaced it with a new wire with added shrink tubing to assist with the insulation. I found out this evening that the coil is shot. No ohm reading between the two ports where the spark plug goes in.

The voltages check out. Turns out the coil is bad. No ohm reading through the ports where the spark plug goes in.
