CLOCK FAILS TO OPERATE.Step 1.Use multimeter to check for 24V DC across recrank inhibit relay K6 (part of AC-DC control relay assembly,18, figure 4-19).If present, refer K6 to next higher level of maintenance for testing.If 24V DC is absent, proceed to next step.Step 2.Use a multimeter (set for AC voltage) to check for 120V AC at terminals 1 and 2 of digital clock M111 (78,figure 4-22).If 120V AC is absent, check wiring connections.If 120V AC is present, refer digital clock to next higher level of maintenance for testing.13. CLOCK CANNOT BE ADJUSTEDStep 1.Test 50/60 Hz switch S52 (9, figure 4-22) according to paragraph 4-40.If defective, replace switch (see paragraph 4-40).Step 2.Test HR ADJ switch S51 (10, figure 4-22) according to paragraph 4-40.If defective, replace switch (see paragraph 4-40).Step 3.Test MIN ADJ switch S50 (10, figure 4-22) according to paragraph 4-40.If defective, replace switch (see paragraph 4-40).Step 4.Test HOLD TIME switch S49 (10, figure 4-22) according to paragraph 4-40.If defective, replace switch (see paragraph 4-40).If malfunction persists, refer digital clock M111 (78, figure 4-22) to next higher level ofmaintenance for testing.14. GENERATORS CANNOT BE SET UP IN PARALLEL (DROOP).NOTEThis malfunction assumes that each generator functions properly as a single unit.4-32
