Thought I'd solved this problem by cleaning the engine grounds but it's back. When the DESS key is put on the post while "reading the key" is displayed there is a short chirp every 10 seconds and the usual two beeps are never heard and I can't start the ski. I can't find that code on the forums or the service manual. The check engine light isn't on. There has to be info on that beep code somewhere before I start swapping parts aimlessly. 2013 Sea Doo RXT 260. Thanks!!
