Recently my uncle gave me his 1996 Seadoo XP. I knew up front I would need to get a new battery for it. Before I did so I jumped the Seadoo off on the old battery to make sure it would run and it started up several times no issue as long as power was supplied from an outside source. The next two days consisted of me getting a new battery and pouring the electrolyte just as the instructions told me to and charging for the proper amount of time on a 2amp charge. I charged it for 10 hours and then tested it and it read 12.8 volts. In my eyes that should be plenty for use since the directs said it should be around 12.7. I then installed the new battery and put the key on but now confirmation noise was made (should be a double beep). Obviously because of that the ski would not crank. Anyone have any ideas on what is wrong or if I did anything wrong. I am 18 with very little jet ski maintenance experience but I did test the starter solenoid using a screw driver and tested the key fob as well. Not sure where to go from here. Any advice would be greatly appreciated. Thanks.
