First, thanks to all who responded!! During all of the readjusting, tightening, etc it started to fire?!? I don't know what the problem was, but it is now running well. I do have a question though. This tractor was converted to 12V with an alternator and positive start sometime in its past. It has what appears to be an original (not original to the tractor) ballast resister (1.1 ohm disconnected) in line before the coil (12V with external resistence with 1.8ohm resistence disconnected). I am getting 12v all the way to the points (open). Should this ballast resister not drop the voltage to 6v? Also, is this the correct setup?
