Starting spark frequency? (ignition issues...)

there is a dual ballast resistor, but it's been wired to so that the bottom and top resistors have been bypassed)

This is troubling to me.

If you have a standard coil and a standard mopar electronic ignition system you still need a ballast resister.

IIRC the older 5 wire ECUs need a ballast resister for their power feed and the coil needs it's ballast resister

The newer and I suspect all replacement ECUs are 4 wire and the ECU does not need a ballast resister on its feed. BUT you still need the ballast for the coil.

So if you bypassed both the top AND the bottom ballast resisters you might be cooking the coil.

Now if you have aftermarket coil, dist, and ECU they may have internal protections and be specifically designed to run on full battery voltage.
