276-7273     Sensor Test Box (1)    
( 1 ) Instrument used to test Cylinder Position sensors.Two short jumper wires may be needed to check the continuity of some wiring harness circuits by shorting two adjacent terminals together in a connector. A long extension wire may also be needed to check the continuity of some wiring harness circuits.Except for harness tests, the use of certain test equipment is not recommended for use on modern Caterpillar electrical circuits. Such testers include the following examples: the 8T-0500 Continuity Tester and 5P-7277 Voltage Tester .Note: A procedure has been developed to test "In Cylinder" Position Sensors. Reference Special Instruction REHS7338, "Procedure to Test the Position Sensor of a Hydraulic Cylinder". Optional Service Tools
