Re: Motor Won’t Shut Off…Again

[Don]

Well, I think that terminology might just be the cause of confusion here…."Trigger/switch box" is a term used by merc, whereas OMC always referred to them as the powerpack. When you say trigger, I am "asssssuming" you replaced the sensor coil or the complete potted stator (electric start models). Perhaps we are misunderstanding what part you replaced that solved the problem.
In any event, the 82 35hp with CDII has two harness leads coming off the powerpack (along with one ground lead). One of the harness leads has three terminals: the two coil leads (orange or perhaps brown looking) and the stop lead. The stop lead is black/yellow tracer, but sometimes the engine harness side might just be black. The other powerpack harness lead has four leads: two brown leads (one with yellow tracer that are charge coil leads (the term charge coil is confusing because it is often understandably confused with some sort of alternator function, but is an ignition part) and the two sensor leads (one black/one white).
Just because this is the way the 82 35hp rolled off the assembly line does not mean the ignition system has not been messed with/altered/cobbed up along the way. Someone could have used a later style powerpack and fudged the leads accordingly. Jeez, for all we know, someone could have changed this ignition to UFI, who knows!
So, I too don’t think the sensor could have caused this engine not to shut off properly. I’m thinking funky connections probably got repaired coincidentally when the sensor was replaced. BUT, I know enough about my lack of electronics knowledge to "never say never". Nonetheless, the important thing is it works properly now…..I too have learned never to question success….
