hello all, running a carbureted 5.0 with a Dura-Spark II ignition. was running fine then all of a sudden the car died and there's no spark at all. here's what I've tried so far.

the ignition module is new (third one I've tried), connected correctly and has power to it. the ignition coil is new (fourth one I've tried). the distributor is new with a new stator assy. the voltage output at the coil connector reads 7-9 volts while cranking. the internal resistance of all the coils I've tried read zero ohms. the coil-to-distributor wire is new. when the coil connector is plugged onto the coil, the voltage no longer reads 7-9 volts, but reads zero. I've replaced every single piece of wire in the harness including removing all connectors and soldering all wires together. I'm completely stumped. does anyone know what the coils' resistance should be???
 
Are you using the duraspark style box still or an HEI module? I went through 3 duraspark boxes before I changed to a HEI module setup and haven't had a problem since.
