Abstract: An improved wheel alignment turntable for supporting a wheel of a vehicle. Embodiments include a turntable having a base, and a top plate for receiving the vehicle wheel, the top plate being mounted to an upper surface of the base for rotational and translational movement relative to the base. A pair of paddles, removably adjustably attachable to the base, engages a peripheral wall of the top plate for maintaining the top plate in a predetermined position relative to the base while the vehicle wheel is being positioned on the turntable. The paddles are easily removable when the wheel is supported on the turntable. A plurality of slide pads are removably mounted to a lower surface of the base, for enabling sliding motion between the turntable and a surface of a lift without damaging paint on the surface of the lift. The slide pads are stackable against one another for adjusting height of the turntable relative to the lift.

Abstract: An electronic automotive vehicle service equipment system includes a computer interface board adapted for installation into a non-dedicated, general purpose computer to serve as the central processor for the automotive service system, or as a component of multiple systems, while enabling the computer to also be available for other applications. The interface board provides microprocessors for controlling various data receiving and transmitting functions through multiple ports between the computer instruments integral to the vehicle service system.
