(1) Set multimeter select switch to
volts dc.
(2) Disconnect connector MC127 from
throttle position switch.
(3) Connect positive (+) multimeter lead
to harness connector MC127, terminal
A.
(4) Connect negative (–) multimeter lead
to a known good ground.
(5) Turn ON ENGINE switch
(TM 9-2320-364-10).
(a) If 22 to 28 vdc are not present,
perform Steps (6) and (7) below
and repair wire 1956 (see
schematic Fig 2-67) or notify DS
Maintenance.
(b) If 22 to 28 vdc are present, turn

(6) Turn OFF ENGINE switch.
(7) Connect connector MC127 to throttle
position switch.
VOLTAGE TEST
Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry or tools contact positive electrical
