    Electrical issue with my RXP... Now it won't start at all....

    Last year my ski liked to run without the DESS switch on, this happened a few times and went away so I ignored it. But this ghost came back Saturday. I was out all day and all of a sudden it shut off by itself. Turned it back on and 30 seconds later it shut off again. I noticed it started saying "KEY". I pulled the DESS off and let it sit for a few minutes (wondering what the F*CK was happening). Then I plugged it back in and it started up right away without having to push the start/stop switch. This must have happened a dozen times trying to get home before it shut down completely on me.

    Got it on the trailer after towing it in and plugged up the DESS and now nothing except a clicking noise and the dash is completely blank, but if I hold the DESS slightly to the side without the center touching the display comes on and the clicking stops. If I plug in a DESS from another key it acts normal like it should and shows "KEY". I noticed without anything plugged it was still making a buzzing/sharp click noise front the front of the motor. It would stop when I disconnected the harness that leads to the DESS and start/stop switch.

    So I am lost here, I plan to go to the stealership to have a new key programmed (lost my spare) and see if it's the key. If not I plan to switch out the DESS and/or start/stop switch. I am thinking something is shorting somewhere but not sure. Anyone have any clue or heard of this happening before?

    So took it to the dealer and found the start/stop button was corroded. So that's on the list, but when they tried a new key, it wouldn't read and it gave a few codes. Thing is they sent out some kid tech to do the key so he had no clue, but the good thing is he didn't charge me to sit there for an hour looking for a solution ( none found though ).

    I see another thread on here where a speedster has the same issue, all I hear now is a clicking but nothing turning. When I look back at the prop it just shakes when trying to start.

    Any ideas? Maybe the ECU?

    I had a weird clicking issue once, and turned out
    To be my RR ECU was bad and would drain the battery
    / had a short. Fixed it with another Ecu

    Changed almost everything to find cylinder ones plug was smashed, not sure the damage yet. Weird how it just shut off like that though.

    The smashed spark plug is unrelated to it started itself and is much more important. if you have no compression in that cylinder. your gonna have to take the head off and its not gonna be pretty.
