 TM 9-2320-364-20-1
Allow engine to cool before performing
troubleshooting maintenance. If necessary
use insulated pads and gloves. Hot engine
components will burn and cause injury to
personnel.
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.
RESISTANCE TEST
(1) Are there more than 10,000 ohms or
an open circuit measured between
wires 916 and 952 at vehicle harness
connector MC18, terminals A3
and C3?
(a) If less than 10,000 ohms are
present, repair wires 916 and/or
952 (see schematic Fig 2-1) or
notify DS Maintenance.
(b) If more than 10,000 ohms are
present, perform Step (2) below.
(2) Are there more than 10,000 ohms or
an open circuit measured between
wires 916 at vehicle harness
connector MC18, terminals A3
and a known good ground?
(a) If less than 10,000 ohms are
present, repair wire 916 (see
schematic Fig 2-1) or notify DS
Maintenance.
(b) If more than 10,000 are ohms
present, wire 916 is OK, go to
Step 9 of this Fault.
VISUAL INSPECTION
Check terminals at vernier control and
vehicle harness connector MC18 for
damage; bent, corroded and unseated
pins or terminals.
(1) If terminals are damaged, repair
connector (Para 7-101), go to Step
11 of this Fault.
(2) If terminals are not damaged,
go to Step 10 of this Fault.
