You have already received lots of good advice. I suspect that somewhere in all your parts changing you left out something simple yet vital. I would not be surprised if it is the insulating washer on the condensor. Here is a photo of that washer.

Unfortunately, it sounds like you may not be familiar enough with the assembly to be able to understand where it goes.
Do you have a Model A Mechanic's Manual or any Model A parts catalogs that have diagrams that might enable you to double check the assembly sequence of the parts that you have changed?
It is important to step back and take a fresh calm look at everything and use a systematic approach to check each point in the electrical system. If you can't find the problem from what has already been posted, you might be better off calling the local club guy back and seeing if he or someone else has the time to come help you find the problem.
