Not a Spyder owner so I can't relate to the DESS issue but, I am a Ski-Doo owner and they too have the DESS system and I've never heard of a single issue on one of their snowmobiles. Maybe it's an entirely different system? It is surprising that an electrical minded individual hasn't figured out how to turn the system off. Sounds like a good aftermarket business opportunity!
