I'm working on getting my 86 johnson 150 hp j150tlcdc tuned up and its coming along nicely. I wanted to hook up a tach to tweak it some more but I seem to have some funny electrical problems.
When I got the boat it wouldn't shut off unless I turned the key off and then pushed the key in everything else seemed to work well so I never really paid much mind to it. The p/o had a new control box installed about a year before I bought the boat but never used it due to an illness so he had nothing to say about the funny key switch. I tried to hook up an old omc tach I had laying around tonight and that's where things got odd, I found the wires under the gunwale for the tach, grey, purple and black. I hooked them to the wires sticking out of the tach and voila.... Nothing. I wasn't sure if the tach was a working unit so I touched the ground and the grey to the battery and the needle flinched so it looks like it might work. So I hooked the tach back up and started the boat on the hose and proceeded to play with the wires, at this point I received a nasty shock from the wires on the tach. I'm not sure which ones I got the shock from but I wasn't willing to try it again to find out. After the feeling came back to my fingers I turned the key off and the motor shut off without pushing the key in!!!!. WTF, I said so I tried it again and it did it several more times, so I unhooked the tach and tried it again and the darn thing wouldn't shut off until I pushed the key in.
My electrical skills are rudimentary at best so this one I weirding me out. If any one could shed some light on this, (pun intended) it would be greatly appreciated.

I had that experience a couple days ago, lol, still haven't found the screwdriver that flew out of my hand at that point :facepalm:
