    I assume you have a shop manual and a decent voltmeter.....

    as far as ignitions go a pwc isn't that far off from a motorcycle..but it can get expensive if you miss something obvious. Having a donor ski is a big help.

    The very first thing to suspect on an older Yamaha for a crank but no start is the kill's got two circuits..I run into this on a regular basis..when the lanyard is installed it manipulates two circuits one for the starter system and the other for the ignition system..typically the ignition side fails and the engine will crank..but no power to the cdi to spark it up.

    don't bother trying to fix the switch..the are poorly designed and they simply wear out. the most ou can do for it is to spray some wd-40 under the little rubber boot

    disconnecting the white/black two pin connector coming from the handle bars should remove the issue and allow the engine to start..but you won't be able to shut it down without reconnecting have the water hooked up and ready to go.

    the wiring diagram is a bit misleading..the donor ski may have the same kill switch problem

    no computer skills needed for this issue..just a methodical troubleshooting plan.

    a replacement switch can be a wallet flattening don't be surprised at the cost. Those things are brutal expensive and I would suggest a new the used ones out there could be a few moments from providing the same hair pulling tooth grinding affair.

    I've got a cdi and a stop/start switch for a raider 1100 if you want to give them a try. Send me a pm or post something if your interested. I don't know for sure if they work but I'd be willing to send them your way.

    That kind of sounds like my problem. I replaced my CDI from a ski that did fire, and on this ski, I still don't get any fire. I recall checking the stop/start switch, but I might have checked it wrong with a multimeter. How could I get it to stop if I started the ski with it unplugged?
