What are you talking about? Sig just told you that you absolutely need the ballast resistor... without it, I'm not exactly sure what will happen, but that B2 coil won't last long and your truck won't run right.so no one realy know about aftermarket coils for us 80-86 guys and gals? what will happen if i just dont run the resister? or should i just go buy another crappy stock one?
Can you explain why? I am not familiar enough with the TFI to know why this would be a downgrade.BTW, does your factory ignition system have a TFI module and a TFI coil? If so, this Blaster 2 coil would be a serious DOWNGRADE.
That's because it's a capacitive discharge (~440V to the coil primary) ignition, bearing little semblance to the original ignition. The coil's charge time is almost NIL compared to a factory Duraspark/TFI system.I have a blaster coil on my fairlane with no resistor and has worked for around 10 years.Stock duraspark dizzy running with MSD 6a box.Never any problems.Pulls good to 7500.
