I have a 2004 Yamaha xlt800 waverunner. My neighbor borrowed it yesterday and flipped it. Shortly afterwards he said the ski would not turn off so he had to disconnect the battery to shut it down. I took the starter switch from the handle bar to check it for corrosion and found none. I disconnected the switch completly and put the battery termenal back on and it started as soon asI did that without the switch being connected. So I'm thinking that rule out thestarter switch as the problem. ANY suggestions to what may be causing this would be appreciated.
