No Fire!

Hey guy's, 67 barracuda, has been driving fine, sat for about a week and couple days, went to start it and no fire. Pulled the coil wire at dist. and it seems I am getting no spark. 2 months ago it did this and I had to replace the ballist resistor and it worked fine. I always keep a spare one, so I install a new one and still no fire. I noticed after cranking it a couple of times, that the resistor got very warm and started to smoke. So I stopped. I noticed every one of these new resitors have the open back where you can see the resitor, seem kind of cheap. Any ideas, Thanks!
I'm not sure which ballist you have,but there are 2 circuts that go to it.One is the start mode where the resister is sorta by=passed,the other is the run mode.Sometimes when the resister has failed it will crank and start and when you let off the key it will stall,the other is a crank no start.Try using a test ligh or volt meter on the coil and see when power is getting to the coil.That would be your 1st test:dink:
If you are using an MSD or other aftermarket ignition,the ballast resister is usually removed.Now tell us whatcha got:toothy8:
