Duraspark module overheated and engine died

My points to electronic conversion suffered this problem, just started, set the timing and was idling, like ten minutes or more, suddendly the engine died, no spark, inmediately I noticed the module was very hot, so was the ignition coil, it's a TFI "square" coil from a 1987 Econoline I6, the module is a new Spartan brand name blue module.

I cooled the module with a wet rag and the engine came back to life.

I hooked up the module and the coil with full 12V, no ballast resistance for the coil, I'm feeling this is the problem, maybe this coil needed a ballast resistor ?

I have this 1.6 ohmm ballast, if I install this, will the coil run cooler and put less strain in the module, so it won't overheat? or the TFI coil is wrong for the Duraspark ? it was running fine with the points, never missed a beat, never tested how hot it run with the points though, but I did used the ballast resistor with the points.
