Please help I brought this sea doo xp800 in the fall was told it needed a start button.it needs more. I have no power to anything. No beeps no click or anything.I have installed new start/stop button. Replaced new post for lanyard, checked fuses. Unplugged all connectors and checked for breaks, replaced ground cable. Turned engine over by hand and its fine. Took a screwdriver across solenoid and engine will only try to turn. (Like engine is locked up or battery is dead but it’s new and starts my Polaris ski fine) The only power that I can get is if I hold in on the start/stop button I’m able to move the vts.
