4-3 h. i . j. k. l. m. n. o. p. ARMY TM 9-6115-644-24 AIR FORCE TO 35C2-3-446-12 MARINE CORPS TM 09249A/09246A-24/2 With multimeter  set on OHMS, check across terminals  9 and 10. Slowly increase output voltage of G1. When voltage  reaches 23.9 +/-1.4 VAC the relay should trip. When relay trips, circuit 9 and 10 should close and circuit 11 and 12 should open. Return output voltage of G1 to 0 and open S1 allowing relay to reset. Place  switch  S2  in  “B”  position  and  close  switch  S1. Repeat  steps  f.  through  i. Place switch S2 in “C” position and close switch S1. Repeat steps f. through i. The voltages at which relay trips in positions A. B, and C should be within 1 volt. Replace any relay found to be defective. Install relay, paragraph 2-56-4. FIGURE 4-1. Test Circuit GOVERNOR    CONTROL  UNIT. High voltage is produced when this generator set is in operation. Improper operation could  result  in  personal  injury  or  death. 4-3-1 Troubleshooting  Procedures a. While holding the Master Switch (S-1) in the “START” position, check for the voltage from pin positions 1,3,5 on the GCU (A-5) to Ground. The readings should be battery voltage. If there is no voltage between any of the connections, the GCU  (A-5) is not receiving the proper voltage and the wiring harness should be checked. Refer to FO-1. NOTE With  the generator running the voltage will read zero. 4-5
