ABSTRACT:
A vehicle wheel alignment system includes a battery powered wheel alignment sensor assembly and a a storage station for the sensor assembly. The storage station is designed to hold the sensor assembly by the wheel adapter in a predetermined position with respect to the storage station. It also includes a power source for charging the sensor assembly battery. An interlock arrangement automatically interconnects the sensor assembly battery and the power source to charge the sensor assembly battery when the sensor assembly is disposed in the predetermined position. A display is operatively connected to the wheel alignment sensor assembly for displaying measured alignment information. A battery level measuring circuit measures the state of discharge of the sensor assembly battery by examining the battery voltage and generates a signal proportional to the measured battery voltage. The display is controlled to also display an analog representation thereon indicative of the level of discharge of the sensor assembly battery.
