I am having basically the same issue as VanderLaan.
This is what is happening with my 2009 RXT 215. The key is on the post, and I get the all good two beeps. When I push the start button all I get is a click for the engine. The engine does not turn over at all. I did order and install a new starter solenoid from the Sea-Doo warehouse. I do have the battery disconnected when doing this repair. After installing the starter solenoid and reconnecting the battery. I sill get the click with no engine turn over.
I pulled out my battery tender jr. and it blinks which means the battery is 80% charged. Then I hooked up my battery charger and it showed the battery was charged.
I felt like the starter solenoid was the best place to start. Even though I didn’t hear the click from the solenoid. The click is coming from the engine somewhere. Any ideas or trouble shooting ideas would be greatly appreciated. I sure don’t want to take it to the shop, but I may have to.
Thanks
