The pointer is the red ring, it is possible for it to be "hiding" behind the wire connector.
pop the dial off (it just snaps on) and take a small magnet to the back of the dial to move it, while doing that check your panel indications, if all is well take some sand paper and clean out the recess in the gauge. If it doesnt work with a magnet start by checking wire connections. Good luck
