I installed the Honda heated grips last night. My ride to work this morning was 30 degrees and the grips worked great. My question is about the controller. The panel shows distinctive red dots that i assumed would have detent positions on the switch itself. However my switch seems to have many more detents than there are red dots. It seems to be more of a continuously variable type adjustment with stops at each end. Is this normal or should there only be detent positions at the red dots?
