Glow Controller
The glow controller is attached to the inside of the con-
trol panel cover (Fig. 42).
NOTE: Refer to Chapter 8 - Foldout Diagrams when
troubleshooting the glow controller.
Controller Operation
1. When the ignition switch is initially placed in the ON
position, the glow controller energizes the glow plugs for
10 seconds. The console glow plug indicator light will
also be illuminated for 10 seconds.
2. When the ignition switch is turned to the START posi-
tion, the glow plugs will energize as long as the switch
is held in START. The console glow plug indicator light
will not light.
3. WhentheignitionswitchisreleasedfromtheSTART
to the ON position, the glow plugs will de- energize and
the console glow plug indicator light will remain off.
Controller Checks
1. Make sure there is power from the battery.
2. Disconnect the wire harness electrical connector
from the engine fuel stop solenoid to prevent the engine
from starting.
3. Place ignition switch in the ON position. Verify the fol-
lowing while in the ON position:
A. Glow plug indicator light is on.
B. Glow relay is energized.
C. Glow plugs are energized.
D. Glow plug indicator light goes out and glow plugs
de- energize after approximately 10 seconds.
4. PlaceignitionswitchintheSTARTposition.Verify
the following while in the START position:
A. Glow plug indicator light is out.
B. Glow relay is energized.
C. Glow plugs are energized.
D. Power exists at terminal 1 of the glow controller.
NOTE: If there is no power to terminal 1 of the glow con-
troller, verify continuity of the circuitry from the ignition
switch to the controller and perform Step 4 again (see
Chapter 8 - Foldout Diagrams).
5. If any of the conditions in Step 3 are not met or power
to terminal 1 exists and any of the other conditions in
Step4arenotmet:
A. Verify continuity of the circuitry from the battery to
the glow relay and glow plugs (see Chapter 8 - Fold-
out Diagrams).
B. Verify continuity of the circuitry from the battery to
ignition switch, glow controller, glow plug indicator
light, glow relay and ground (see Chapter 8 - Foldout
Diagrams).
C. Replace parts as necessary.
6. Connect wire harness electrical connector to the f uel
stop solenoid.
