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.
