volts dc.
(2) Open engine cover
(TM 9-2320-364-10).
(3) Connect positive (+) multimeter lead
to wire 1957 at the turbo boost
pressure switch.
(4) Connect negative (–) multimeter lead
to a known good ground.
(5) Turn ON ENGINE switch.
(6) With the aid of an assistant, observe
multimeter while throttle control is
pushed down completely.
(a) If 22 to 28 vdc are not present,
repair wire 1957 (see schematic
Fig 2-67) or notify DS
Maintenance.
(b) If 22 to 28 vdc are present perform
Step (7) below and go to Step 17
of this Fault.
