Cheers... I have a 1979 70hp 3cylinder Merc with stator, trigger, rectifier, 3coils - no points. The plugs fire hot and blue and in time when out of the motor, but when replaced in the motor - no fire (checked with a timing light). Two plugs out and one plug in gives me fire on all. Two plugs in and one plug out gives me hot fire on the out plug and intermittent fire on one of the in plugs. The battery is hot and spins the starter fast. Someone suggested disconnect the rectifier and see if it fires. Did that - same scenario. All wires are good with no spark jumping. I don't know how to check the stator or trigger - only have a volt/ohm meter. Can someone help? I'm completely baffled.
