ARMY TM 9-6115-604-12 NAVY NAVFAC P 8 633-12 c. Install. See Figure 4-75. (1) Install LUBE OIL TEMP gage M2 from front of cabinet C door while assembling bracket from the rear. (2) Secure with hexagonal nuts and lockwashers provided. (3) Connect wires and resistor and discard tags . 4-122. COOLANT TEMP GAGE M3 (10, Figure 2-1). COOLANT TEMP gage M3 indicates engine coolant temperature. Dangerous voltage levels may be present at components located within cabinet C. Observe all applicable safety precautions as outlined In Chapter 1, Section III, of this manual. NOTE Two persons may be required to perform the following procedure: a. Test (1) Set 24 V dc CONTROL POWER CIRCUIT BREAKER CB1 to ON. (2) Disconnect sender lead from COOLANT TEMP sender MT3 on the left thermostat housing on the engine block (see Figure 3-3) COOLANT TEMP gage M3 pointer should go to zero. (3) Short to engine ground the disconnected sender lead from COOLANT TEMP sender MT3 COOLANT TEMP gage M3 pointer should now deflect full scale upwards. (4) Set 24 V dc CONTROL POWER CIRCUIT BREAKER CB1 to OFF. (5) Replace COOLANT TEMP gage M3 if It fails to pass this test. Reinstall disconnected sender lead on COOLANT TEMP sender MT3 after test. (6) Check wiring using FO-1, and check sender in accordance with paragraph 4-123 if gage is good. b. Remove See Figure 4-75.
