Glow Controller
The controller is located under the right lower corner of
the instrument panel.
Controller Operation
When the ignition switch is placed in the RUN position,
the controller energizes the glow plugs and lights up the
glow lamp for 10 seconds. When the ignition switch is
held in the START position, the glow plugs will energize
while the switch is held in START and the glow lamp will
not light. When the ignition switch is released from
START to RUN, the glow plugs will deenergize and the
glow lamp will remain off.
Controller Checks
1. Make sure there is power from the battery.
2. Disconnect electrical connector to the fuel solenoid
to prevent the engine from starting.
3. Place ignition switch in the RUN position. Verify the
following while in the RUN position:
A. Glow indicator lamp is on.
B. Glow relay is energized.
C. Glow plugs are energized.
D. Glow indicator lamp goes out and glow plugs
deenergize after 10 seconds.
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
Electrical Schematics and Diagrams).
4. Place ignition switch in the START position. Verify
the following while in the START position:
A. Glow indicator lamp is out.
B. Glow relay is energized.
C. Glow plugs are energized.
D. Power to terminal 1 of the glow controller.

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
step 4 are not met,
A. Verify continuity of the circuitry from the battery
to the glow relay and glow plugs (see Electrical
Schematics and Diagrams).
B. Verify continuity of the circuitry from the battery
to ignition switch, glow controller, glow lamp, glow
relay, and ground (see Electrical Schematics and
Diagrams).
C. Replace parts as necessary
6. Connect electrical connector to the fuel solenoid.
