Lay flat with compressor hose cover up and handle towards you. As you look at the unit, just to the right of the handle and below the cigarette lighter power outlet is a two position switch. If you look close you can read the On and Off positions. By turning this switch to ON it powers the cables that are wrapped on the back of the unit. Unfortunately my experience has been that the internal battery does not hold a charge long enough to be very useful but on the off chance that I just got a lemon, the above procedure will work. Remember red cable to positive, black to ground/negative.. There is a light to the left of the cigarette lighter outlet if you hook the cables up backwards. It is a good idea to hook the cables up before turning the unit on.
