i recently purchased a 1997 sea-doo spx,ran when last ridden.battery was dead so i replaced and now i cant get any power,checked all the fuses i could find (4) 2 in front box and 2 in back box.checked and cleaned all wires and grounds.when it was put up after last ride,the previous owner left the dess lanyand hooked up.dont know if that is bad.what else is there to check?can jump across selonoid and motor will spin.but it wont beep,start button doesnt do anything,no clicking of any kind.any help would be greatly appreciated.also wife found on internet that if you replace battery you have to take to dealer to have security code reset,is that true or is it something i can do myself.have shop manual coming also
