I use my new 07 IQ Touring 600 for the first time a couple of weeks ago, and the rear handle bar warmers only heat up about 2" up the grip, after an hour on the trail. Not good! I called the dealership where a purchase the new machine, and was told to alternate the front and back warmers and that should work. It's a comon problem. I couldn't find that operation in the manual. Shame on Ken's Sports Center WI.
I then called G&G Muskego Wi. and they were very helpful.
They said the electrical system may cut out the rear warmers if there is a problem. I have voltage at the rear plugs, 13VDC and 7 ohms on each set of coils. Please help!
