(1) Set multimeter select switch to ohms.
(2) Is there continuity between clearance
lights relay R2, terminal 86 and a
known good ground?
(a) If there is no continuity, repair
wire 1435 (see schematic
Fig 2-34) or notify DS
Maintenance.
(b) If there is continuity, wire 1435
is OK.
CONTINUITY TEST
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) Set multimeter select switch to
volts dc.
(2) Connect positive (+) multimeter lead
to wire 1012 at clearance lights relay
R2, terminal 87.
(3) Connect negative (–) multimeter lead
to a known good ground.
(4) Turn ON ENGINE switch
(TM 9-2320-364-10).
(a) If 10 to 14 vdc are not present,
perform Steps (5) through (7)
below and replace relay R2
(Para 7-95).
(b) If 10 to 14 vdc are present,
perform Steps (5) through (7)
below and repair wire 1012 (see
schematic Fig 2-34)
or notify DS Maintenance.
