MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
7. GENERATOR SUPPLIES NO VOLTAGE TO LOAD.
Step 1. Check main circuit breaker for ON position on ac output control box.
Place circuit breaker in ON position. If breaker will not stay on, perform the following
actions:
Make certain load leads are attached to the correct load terminals.
Make certain connections are clean and tight.
Verify load is not excessive to generator capability and does not have an internal short.
Notify higher level maintenance.
8. GENERATOR SUPPLIES IMPROPER (UNDER OR OVER) VOLTAGE FREQUENCY TO LOAD.
Step 1. Check reconnection switch on ac output control box.
Make certain switch position matches load.
Disconnect load before switching.
Step 2. Check load terminal board (paragraph 3-17).
Make certain load leads are attached to the correct load terminals. Make certain
connections are clean and tight.
Step 3. Check engine speed.
Adjust engine speed by turning speed control assembly until frequency meter on
control panel indicates 60 Hz with load on Generator Set.
If engine speed cannot be brought up so that Generator operates at 60 Hz, check
external governor linkage for binding and check steps under ENGINE STARTS
BUT DOES NOT RUN SMOOTHLY.
If engine speed cannot be brought down so that Generator operates at 60 Hz, check
external governor linkage for binding or notify higher level maintenance
(paragraph 3-21).
3-11. BATTERY ASSEMBLY.
a. Inspect (see figure 3-2). On generators equipped with
acoustic suppression kit (ASK), remove batteries access door for
Inspection.
(1) Inspect battery cable terminal connectors (2), (10) and
(11) for corrosion, deterioration, or physical damage. Inspect
battery terminal covers (16) for proper installation and physical
condition. Replace if cracked, split or torn.
(2) Inspect cables (l), (3), and (4) for breaks, damage and
Section V. OPERATOR MAINTENANCE PROCEDURES
(3) Inspect battery top frames (5), bottom frame (12),
and tray (13) for corrosion or physical damage. Check to
see that frame is held securely in place and that all
attaching hardware, nut (7), washer, (8), screw (14), washer
(15), and bolt (9), is securely in place. Check that frame is free
of electrolyte.
(4) Inspect battery (6) for leaks or cracks. Check top
of battery and battery caps for cleanliness. Check bat-
tery electrolyte (liquid) level. Level should be
deteriorated insulation.
