I have a 2011 IQ Turbo FST with a heated shield plug. This week my electrical cord for my helmet started on fire. The cord melted. I tried to plug the adapter cable from the helmet directly to the snowmobile and that started to pop. Dealer won't help because it is two months out of warranty (only 600 miles on it!). Any ideas on if it is the helmet or the snowmobile? How do you check the voltage coming from the female socket on the handlebars?
There would be 2 different contacts inside the female connector. If its too hard follow the wires back from the plug to where ever its hooked up to and test there. Most people (as far as i know) have the helmet wired with the heated handlebars.
This same thing almost happened to me on one of my sleds. The sled was warming up while i was gearing up and when i went to plug in my visor, I noticed the (LONG WIRE) wire was very hot. (short wire was on the helmet) A bit longer it would have been GOO. I the realized that the cord was laying on the floor board and was shorting. I am thinking the wires need to be switched, So the outer portion of the connecter is ground.
We are just careful for now with that wire until i check it out.
If you get a hold of the instructions, you would see that the center pin is hot, red or positive from the battery. The outside is ground, black or negative. That way, the female socket can never ground out to the frame.
My wife's heated visor will not work on sleds that have reverse polarity. Diode (LED) on the visor prevents reverse polarity.
