Rrrrrrr, need help on this one.

The condenser on the coil should be connected to POSITIVE side of coil. It is there to supress radio noise. I would indeed remove it until you find this cause.

40a is likely not large enough. You have any idea how large your alternator is? Output current that is?

I have few ideas. This is weird.

So it still does not start? You have a test light? Some alligator clip lead "test leads?" How about a multimeter. We can make a few checks
I have most necessary tools. Multimeter, etc. The alternator is probably 60 amp. Most are. No mistake, condensor was attached to negative side of coil. Previous owner replaced coil not long ago and I believe he hooked the condenser up incorrectly. Based on he didn’t know how to fix basic stuff. Kickdown linkage, 2 barrel carburetor choke adjustment, etc.
But, the car ran fine. As far as starting it and it idling, etc.
