    1994 SL750, random engine stopping, handlebar Stop button needed a spring

    I have a 94 sl 750 that i finally got on the water this year. After unloading and running it around the lake for about 15 minutes, i docked and let it sit for a bit.

    Now after trying to get back out, I am finding that the engine dies in somewhat of a pattern, and sometimes for no reason. If I let the engine sit idling, it will generally not die on its own. If I crank the steering left or right quick, seems to die.

    Sounds like maybe a kill switch/wiring corrosion, but seems to have come out of nowhere.

    Am I looking in the right direction?

    In case anyone was interested, I finally found a fix, without knowing what was previously there. Behind the rubber boot protecting the kill switch, the brass contactor must have had a spring of some sort, as it had been rattling in and out of its position, causing random kills. I stuck a bic pen spring between the shaft and plastic housing, and has been working well.

    Was the original spring inside the switch simply not there? Or corroded?

    I have to assume a spring was in there, because the bic pen spring cut in half worked perfectly, but no, there was no spring inside the switch at all.
