I don't think its a pinched wire. We're talking any contact between the mount and any metal on the bike does it. If I lay them on a towel its great. Both old and new coil sets are doing it.

The only other thing I can think of would be the wires hooked up backwards, or in a way that they are creating a ground on the hot side when the coils are mounted.

Fixed!!!

TOOLS1, first i'd like to thank you so much for going out of your way and taking those pictures of your bike for me.

Got home and decided i'm dumb for not checking for 12v from the coil mounts to the - so did that and didn't get anything, started scratching my head since i was sure they were grounding out some how. put everything back together and it fired up, so i'm like sweet, throw the tank on to go for a ride. put tank on and go to turn it on and it pops the fuse again?! so i tank it off.  starts and runs fine. start jiggling wires and fuse pops. ok, figured out, its a short. buddy and his wife are over and we were coming the backbone over with a fine tooth comb looking for a short, i put a fuse in and start jiggling the wires, buddy's wife starts asking why the key is smoking. BINGO. Turns out when i put the coils on or anywhere in it was pulling just enough on the wires up buy the ignition switch to short, but when i put the coils back in i thought it was fixed and ran all the wires really nice so the tank would clear them (and there was just enough slack for it not to short). so when i put the tank back on it stretched it out and and shorted.  pulled the loom off the back of the ignition switch and the brown wire was not only loose but had started welding itself into the red wire.

thank you so much for your guys time and effort.

Moral of the story, relax and dont get as frustrated as i was. I was going to run it over with the powerstroke or actually pay someone (haven't done that since i was 16, now 25) to fix it for me.

If you took .002 thousandths off of the points then the dwell is wrong.

You have to check the gap when the points are new.

Then check the dwell also.

When the points are new the gap is correct and the dwell is good too.
As the points wear( the plastic rubbing on the points cam) the dwell gets too
large and you have a weak spark or no spark because the gap is off.
The points gap and the dwell ( how long the points stay open) determines how strong and when the
spark occurs.

Trying to check the points gap with a set of worn points is not possible.
The points get holes burned in one side and little mounds of metal on the other side.
Then there is no way to check them.

Also you need to change the condensers the same time that you put in new points.
After the condenser has absorbed so much energy it is finished.
The value in microfarads is marked on the side of the condenser.
