Abstract
A testing apparatus for testing the hydraulic circuits of a vehicle having at least two independent hydraulic circuits including a plurality of supplies conduits, one for each independent hydraulic circuit for receiving hydraulic fluid from the associated circuit, couplings on the supply conduits for coupling each supply conduit to an associated circuit, a return for returning hydraulic fluid to the circuits, a single particle sensor adapted to receive hydraulic fluid and provide an output signal indicative of particle contaminants in the hydraulic fluid, the return being connected to the sensor and a valve for selectively connecting any desired one of the supply conduits to the sensor and disconnecting the remainder of the supply conduits from the sensor so that contamination in any of the independent circuits may be determined with a single sensor.
