2001 Seadoo Bombardier GTX. My jet ski sounds fine as long as it is hooked up to a hose but not in the water. When I put it in the water and drove it the red alert light & beep came on saying 12v low and runs very rough. It does not disperse water out the back little hole behind seat as it should. When you undo either plug wire it sounds the same. Not sure what to do. Any info would be appreciated.
