i'm working on a 1957 235. it has a petronix coil and modual in the disturburtor. when i talked to the folks at petronix, they said that i didn't need to run a balast between the coil and the ignition.

today i noticed that the coil was pretty hot so i just pulled the wire from the coil to the ignition and let it cool down. i'm thinking i do need that ballast. any opinions? what else could cause that to happen?

also, the truck is a complete rebuild so although it has been started and ran up to temp, it has zero road time on it.

thanks
