Started seadoo last week in garage started fine went to start it yesterday completely dead. When I attach dess key no power to cluster just a quick flash on the screen and won't start. I checked all fuses they are good. Battery is good. TOPS is good. Jumped out starter relay and motor turns over but won't stay running. Checked wiring harness going to MPEM did notice corrosion on one of the 30 amp fuses even though it tested good I replaced it anyways and female plug end had corrosion which i cleaned. What am I missing?
