VOLTAGE TEST -726280441

TM 9-2320-364-20-1

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.

Allow engine to cool before performing troubleshooting maintenance. If necessary use insulated pads

and gloves. Hot engine components will burn and cause personnel injury.

VOLTAGE TEST

(1) Connect positive (+) multimeter lead

to power harness connector MC17,

terminals A, B, E and F one at a time.

(2) Connect negative (- ) multimeter lead

to a known good ground.

(3) Turn ON ENGINE switch

(TM 9-2320-364-10).

(a) If less than 10 vdc is present,

turn OFF ENGINE switch and

repair wire 240 or 241 (see

schematic Fig 2-3) or notify DS

Maintenance.

(b) If 10 to 14 vdc are present,

wires 240 and 241 are OK. Turn

OFF ENGINE switch and go to

Step 14 of this Fault.

RESISTANCE TEST

(1) Set multimeter select switch to ohms.

(2) Read resistance between wire 150 at

power harness connector MC17,

terminal C and a known good ground.

(a) If there are more than 5 ohms

present, repair wire 150 (see

schematic Fig 2-3) or notify DS

Maintenance.

(b) If there are less than 5 ohms

present, wire 150 is OK and

perform Step (3) below.

(3) Read resistance between wire 150 at

power harness connector MC17,

terminal D and a known good ground.

(a) If there are more than 5 ohms

present, repair wire 150 (see

schematic Fig 2-3) or notify DS

Maintenance.

(b) If there are less than 5 ohms

present, wire 150 is OK. Go

to Step 15 of this Fault.
