I left the key on after using the ski and the battery was dead. A week later I jump started the ski to get it to start but i noticed the display was not coming on. It turns over but will not fire. The fuses look good and I have swaped out with my other identical ski the relays and the main computer and it rules out them. I have put new plugs in and am now out of ideas of what to try next. If anyone has any suggetions would be great. As I said I have another ski that I can swap parts to help find the problem.
