Adhesives, solvents and sealing compounds can burn easily, can give off harmful vapors and are
harmful to skin and clothing. To avoid injury or death, keep away from open fire and use in well-
ventilated area. If adhesive, solvent, or sealing compound gets on skin or clothing, wash immediately
with soap and water.
Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry or tools contact positive electrical
circuits, a direct short may result. Damage to equipment, injury or death to personnel may occur.
Circuit breakers CB5, CB6, CB12, CB20, CB22,
CB23 and relays R3, R13-R19, R26, R28, R32,
R33 are always electrically hot and can cause
severe injury to personnel. Care must be
exercised when working under the electrical
circuit board cover.
(1) Is continuity measured on wire 1435
between work light harness
connector terminal B and a known
good ground?
(a) If there is no continuity, repair
wire 1435 (see schematic
Fig 2-27) or notify DS
Maintenance.
(b) If there is continuity, wire 1435 is
OK.
(2) Apply primer and sealing
compound to three threads of work
light connector.
(3) Connect work light connector to
work light.
CONTINUITY TEST
(1) Remove 15 screws and two ECB
covers.
(2) Set multimeter select switch to volts,
dc.
(3) Connect positive (+) multimeter lead
to wire 1292 at circuit breaker CB4.
(4) Connect negative (–) multimeter lead
to a known good ground.
(5) Turn ON ENGINE switch
(TM 9-2320-364-10).
(a) If 10 to 14 vdc are not present,
turn OFF ENGINE switch and
replace circuit breaker (Para 7-16).
(b) If 10 to 14 vdc are present, circuit
breaker CB4 is OK.
(6) Turn OFF ENGINE switch.
