TM 9-2320-360-20-1 WARNING Jewelry can catch on equipment and cause injury or short across electrical circuit and cause severe burns or electrical shock.  Remove rings, bracelets, watches, necklaces, and any other jewelry before working around HET Tractor. TRANSDUCER VOLTAGE TEST (1) Turn engine switch to ON position (TM 9-2320-360-10). (2) Move CTIS switch to ON position (TM 9-2320-360-10). (3) Place positive (+) probe of multimeter at positions C (white) of transducer. (4) Place negative (-) probe of multimeter on known good ground and check multimeter for voltage. (5) Turn engine switch to OFF position (TM 9-2320-360-10). POWER MANIFOLD VOLTAGE TEST NOTE · Tire pressures must be 75 psi (517 kPa) before beginning test to measure correct transducer voltage output. · CTIS wiring harness must remain installed to controller and power manifold when performing this test. (1) Place positive (+) probe of multimeter on position 7, wire no 1062 (white), at controller. (2) Place negative (-) probe of multimeter on known good ground (3) Start engine (TM 9-2320-360-10). (4) Move CTIS switch to ON position (TM 9-2320-360-10) (5) Press CTIS START button (TM 9-2320-360-10)   and check for voltage on multimeter. (6) Shut off engine (TM 9-2320-360-10). CTIS WIRE HARNESS CONTINUITY TEST (1) Disconnect CTIS wire harness connector from power manifold. (2) Disconnect CTIS wire harness connector from controller. NOTE Pay special attention to positions 1,3,4, and 7. (3) Place positive (+) probe of multimeter on position 1 of connector at controller end. (4) Place negative (-) probe of multimeter on position 1 of connector at power manifold end and check multimeter for continuity. (5) Repeat steps (3) and (4) for remaining positions 2 thru 10. (6) Install CTIS wire harness connectors back on power manifold and controller. Change 1  2-851.2
