Interesting.
I wonder if somebody wants to measure the voltage entering the grips?
It may be possible to re-wire the feed via a simple potentiometer or 2 position switch with a resistor to bypass the BMW H&S stuff
You shouldn't have to though......not on a modern bike
The 11xx heated grips are toasty as anything...ah well, that's progress for you![]()
It's probably PWM control
