There are 2 switches for the tilt circuit. One is for tilt and the other for tilt back. Take off the plastic cover that covers the hydraulic levers. The switches are at the bottom. The tilt switch is either bad or just needs to be adjusted so that the rod coming from the tilt lever will close the switch. You can tell the two apart by looking for the switch that closes with the lever actuating the switch in both directions.
