Of course the Jake should not operate at idle speed, but I will comment only on the suggestion to turn off the Jake switch off. I do not turn my Jake off and it is always on. I installed a relay that allows the Jake to operate only when the brake lights are on. For me this is a safety issue that in case of an emergency stop, the Jake operates without having to think of switching it on. Thus, the Jake does not operate in city traffic, which enables me to cruise, until I apply the brakes. I have a bypass switch to operate the Jake on a long downhill run when I do not want to use the brakes.
