yeah, thats the idea, you leave it set to level 4 which is 24 degrees (c) or whatever, as long as its warmer than that they dont kick in.
In reality it doesnt work like that tho, as the colder the day is the hotter you want the grips to be so that the heat soaks thru your gloves.
They are still great grips tho, neatest installation abd toasty warm.
Why didnt HD didnt just wire the bars for heated grips at the factory? it would have added about 2 mins to the assembly time and saved hours. the E throttle sender already has wiring for grips, they stop about 4 inches from the sender. Those wires should have been extended to behind the nacelle at least.
