RESISTANCE TEST -726280431

TM 9-2320-364-20-1

Remove all jewelry such as rings, dog tags, bracelets, etc. If jewelry contacts 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.

RESISTANCE TEST

(1) Remove rocker arm cover (Para 3-4

or 3-5) corresponding to injector

identified by Table 2-17.

(2) Disconnect the two wires of the

injector identified.

(3) Short these two wires together.

(4) Referring to Table 2-18, measure the

resistance between the injector

harness connector terminals

associated with the faulty injector.

(a) If 1 ohm or less is present, install

rocker arm cover and notify DS

Maintenance. Injector is faulty.

(b) If more than 1 ohm is present,

repair wires tested, (see

schematic Fig 2-4) or notify DS

Maintenance and install rocker

arm cover.

RESISTANCE TEST

(1) Remove rocker arm cover (Para 3-4

or 3-5) corresponding to injector

identified by Table 2-17.

(2) Disconnect two wires of injector

indicated.

(3) Measure resistance at the injector

harness connector terminals

associated with faulty injector.

(b) If there are less than 10,000

ohms present, repair wires tested

(see schematic Fig 2-4) or notify

DS Maintenance.

(a) If there are more than 10,000

ohms present, go to Step 7 of this

Fault.
