The engine has been shamefully sitting around for the last 8 years, I never even cranked it (no big freshwater lakes in VA Beach.) So now I got the urge, drained the fuel tanks, thoroughly flushed out the fuel lines, cleaned and rebuilt the carbs, changed the spark plugs. New battery, 800 CCA, fully charged. Cranked it off, no start. Tried a couple of times. It used to fire right off with no priming, no fast idle lever, no matter what. I tried priming it, pushing in the key, nothing. Looked in the carb intakes, they were all dry as a bone. Manually cracked the primer red lever, fuel came flooding in. It fired right off and ran but, and this is the big but, only ran when I hold the key switch in the start position. As soon as I let off the full right start position, it dies, no run on, sputtering or anything. I verified that the starter was kicking out like it's supposed to, held it in start and let it warm up a little, maybe a minute or so, no change. When running it sounds absolutely beautiful. It does this with the safety lanyard in place or taken off the switch. Gauges light up and system check is run when key is turned to on. I pulled the key switch out and disconnected it so that I can check continuity across the terminals. From everything I gathered on the internets, the safety stop grounding should happen in the black/ yellow wire, but the OMC manual has the black to black yellow terminals as the on/ off function. I verified this with the meter, it operates correctly, with or without the safety engaged. I put the meter ground lead on the black/ yellow terminal and checked all of the other terminals, with the safety lanyard both on and off, nothing showed continuity. This should be obvious that the safety switch no longer works but before I toss $50 at a new switch, I would like to know which terminals are involved in the safety stop circuit. OMC has nothing in the manual other than on/ off and the primer. Does anyone have a wiring diagram for the switch?
