I have a 6-M2, with 55E5 and 4489 shift assist hooked up to a 460 Ford/OMC. Today I started the engine and all of a sudden it just quit running. I tested for spark with coil wire and had none. I then tested the MSD coil by jumping the green & violet wires and yes the coil wire sparked when jumper was removed. I also now have spark and the engine runs. What's up with that? My question would be is that some sort of reset for the 6-M2 box?
