Im having some troubles with get my Msd 6 plus to work properly. Im running one of those pertronix ignitor kits on my distributor and I wired my car accordingly to that companies instructions but I can only get spark when cranking the engine. I do have the red wire hooked up to the 12v with the key on the ON position. The little red led light on the side of the box also only turns on when the engine is cranking. Anyone have any ideas?
