Engine test stand wiring??

I wired mine just like a car. Chrysler starter relay, extra msd box, and I also put a charging system on it.

Well I know I'm jealous!! If you went a bit further you'd have a dyno!!

To be technically correct, LOL, "you didn't" wire it like a car. The OP is considering using a Mopar ignition, which normally runs a ballast, and would normally have a ballast bypass for starting. That, really, is what all the hooraw is about LOL

A good hot spark is especially important on a new fire, because conditions are likely not optimum. Over/ under primed with fuel, oil in the cylinders, timing a little off and so on
