Ok so I am having trouble with shifting my 3.0 omc out of forward and reverse. So naturally i check the shift interreupt switch. It get continuity when depressed and yes it is grounding . Continuity is good all the way from ground to the terminal on the distributor. BUT it isnt killing the engin when depressed. I tried grounding it in different places and no luck. Would a bad ignition sensor stop the kill?? Anyone heard of a good switch but it still not killing the motor when depressed??
