I recently got the Bronco back on the road after a major rebuild. This included a new Centech harness.
Since then, I have blown a 22 year reliable Mallory Unilite module, a new Procomp HEI module, and then I installed a complete duraspark setup with a new TFI coil.
I have researched and used the ballast resistor when needed, and have taken it off for the TFI/Duraspark setup per the wiring diagrams that I have been finding.
This setup worked great! The Duraspark module was a cheapo knockoff that I bought out of a yard...
Now yesterday on the way home from work, the engine just died at a light. It was an ignition kill, because the tach needle dropped like a rock and then the engine quit. It started back up and I was able to drive a few hundred yards out of the way of traffic. During this time the engine backfired twice, sounded like a shotgun! It has never...ever done anything like this in the 30 years that I have driven this thing. The engine would start, but run a few seconds and just die. I had a backup module that I plugged in and it got me the rest of the way home about 12 more miles. Did not detect any problems with the engine once I switched out the module.
A few other things...the Ammeter needle bounces like crazy all the time. The guage is almost useless b/c of this. I was wondering if I replaced the regulator would that help and could it have caused my module from acting up?
Is my module shot?
It was not hot to the touch when I checked, nor was it that hot in the engine compartment...
I am at a loss...two distrubutor modules and now this? What could be causing this? I ran this truck for decades without ever having problems like this...
Any input is appreciated.
