I have a 1976 Mercury 850 Thunderbolt 85HP Outboard engine. I am getting fire from coils 2,3,4 but not from coil 1. I first thought the coil was bad but I took the wires off coil 2 and hooked them up to coil 1 and then it worked. So all the coils are good Does anyone know what could be causing this problem if so any help would be greatly appreciated. Thanks
