Burning up ballast resisters
I take it you have the resistor the right way and aren't running the coil of the low volt side of the ballast, which is for 5th pin wiring?
I would wanna suspect the ign box.
But you could, once varrifying the coils ballast ohm rating requirment, run a new wire to the coil from the ballast and see what happens.
But when this happened to me I lost the orange box and threw on an msd, no more ballast issue.
