maybe i will give that one a try, does it work with aftermarket coils? i have dyna coils 1.5 ohm.
My HEI design is meant to be used with 2.5-ohm coils or higher. It should work with the 1.5-ohm coils, but the HEI modules will get significantly warmer, so a really good heatsink will be necessary and it should placed where it can get a little cooling air. Or you could put a big 1-ohm, 50 W resistor in series with each coil, but the resistors will get hot.
Just curious, why are you using 1.5-ohm coils? The stock ones should have been roughly 2.5-ohm. New 2.5-ohm or 3-ohm coils would have been the preferred choice to prevent damaging the ignitor. It doesn't sound like much but 1 ohm difference does put a lot more current through the igniter.
But right now, if you haven't doen so, you should still make sure you have the right voltages at the coils and ignitor to make sure it's the ignitor that's dead. Red/yellow should have battery voltage on both the coils and the ignitor, and black/yellow on the ignitor should have zero volts. This should be verified with the ignition turned on, and even better, while the bike is actually cranking. Also with the bike turned off, the black/yellow should have close to zero ohms to the battery's negative terminal.
