REFERENCE INFORMATION
WARNING
Disconnect negative battery cable before
disconnecting and reconnecting protective
control box harness.
There is battery voltage at the PCB at all times.
Failure to disconnect battery cable will result m
damage to equipment or injury to personnel.
Repair wiring or replace harness, refer to
(pare 4-34).
Repair wiring or replace harness, refer to
(para 4-85).
Replace glowplug controller, refer to
(para 4-29).
GLOWPLUGS CIRCUIT
0-4500 OHMS
STE/ICE-R TEST 91
1. Connect RED clip and BLACK clip to the
indicated test points in the question. RED to the
first, BLACK to the second.
2. Start Test 91,0-4500 ohms.
3. Displayed reading is in ohms. Less than 5 ohms
is continuity. If the resistance is over 4500 ohms,
STE/lCE displays "9.9.9.9."
CONTINUITY (RESISTANCE)
M u l t i m e t er
1. Set the voltmeter to an ohms scale of about 1000
ohms.
2. Connect the RED and BLACK leads to the
connections stated in the question.
3. Be sure to read the correct scale. Less than 5
ohms indicates continuity. For an open circuit, the
meter should peg full scale (needle all the way to
the left).
