2006 seadoo GTi 4-Tec had to replace battery and now it flashes sensor and double beeps then every 5 seconds 4 fast beeps. It won’t start it only clicks. The solenoid and starter are fine what is wrong ? I am new to seadoo. Old Kawasaki owner
Sounds like the solenoid to me. Jumping the posts just verifies that the starter is working, not necessarily the solenoid. I would test the solenoid separately. Many youtube videos on that.
So, jumping across the posts actually bypasses the solenoid. Its what you do when your solenoid is bad in order to start the vehicle. Replace that and I bet your troubles go away.
