I would say they never stop working completely, just not as hot. It's intermittent, and so is the severity. Both grips are always the same.
I think it has something to do with the throttle side. When the bike warms up with the heaters on, they're effin' hot when I get on.
Is it a loop of wire or a slider that allows the throttle movement? I'm thinking there is a bad connection there.
Does anyone know if they are wired in series or parallel? What should the current and voltages be?
On my snowmobile, the ecu controls the heater output. Is that true on the F8?
It's probably an intermittent short, that will probably eventually become a permanent short. If the short is in the grip itself, though, you won't feel it the same in both grips. They're wired separately, so a short in the left grip means cold left hand, and warm right hand. So, if they're both crapping out to the same degree at the same time, the short is further up stream.
With mine, I tracked it down to the grip itself, and found a break in the heater wire. I soldered it together, and dabbed a bunch of nail polish on it, velcroed it shut and that's how it's been for the past 2 years.
