No spark, ballast is getting really hot

OK, just got my 70 dart out of storage after sitting for about 3 years. Started up pretty easy. Let warm up and brought back to my house. Shut it off and sat for about half hour. Started up again and warmed up and ran around the block. Went to get on it and heard a pop and it died. Now no spark. I replaced the ballast today and still nothing. One thing though is that the ballast is getting super hot when the key is on. I swapped to electronic ignition 5 or 6 years ago and never had any problems. Any ideas? Thanks for the help.
