Long story short.... Cruising along the '69 decided to sputter & stall out....crank no start on the side of the road.

Checked the obvious wiring etc & all looked good. Unplugged my FBO ign module & plugged in my spare orange box with a ground lead....car fired right up.

Swapped in the orange box permanently on the side of the road....no start again! This time I swapped in a spare coil....car fired right up with spare coil & module.

For shitz & giggglez & re-swapped back in the FBO module on the side of the road & nothing...crank no start.

Get the car home for more diag work. Now I swapped back in the FBO coil....starts no problem now.
Swapped in the FBO ECU...no start.

So now my dilemma....whats up with the coils? When I got home after the ordeal the Mopar resto coil was really hot....I am running the MSD ballast that FBO provides with their kit....need to go back to a "stock" ballast to keep "stock" coil cool?
