No Spark MSD e-curve

[dj3]

I have an MSD e-curve dist. that I cannot get a spark out of, sent one back already and the new one is doing the same. I tried grounding it directly to the battery and providing 12v directly from the battery and i still cant get a spark. Also, swapped the coil and no luck. The only thing i havent hooked up is the tach input and red is to pos orange is to ground on the coil.

Anyone have any ideas.



thanks,
DJ
