Glow Controller
The controller is attached to the electric panel under the
operator seat.
NOTE: Refer to see Chapter 8 – Electrical Diagrams
when troubleshooting the glow controller.
Controller Operation
1. When the ignition switch is placed in the RUN posi-
tion, the controller energizes the glow plugs and lights
up the glow lamp for approximately 6 seconds.
2. When the ignition switch is held in the START posi-
tion, the glow plugs will energize while the switch is held
in START and the glow lamp will not light.
3. When the ignition switch is released from START to
RUN, the glow plugs will de–energize 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 stop sole-
noid 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.
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 Chapter 8 – Elec-
trical Diagrams).
B. Verify continuity of the circuitry from the battery to
ignition switch, glow controller, glow lamp, glow
relay, and ground (see Chapter 8 – Electrical Dia-
grams).
C. Replace parts as necessary.
6. Connect electrical connector to the fuel stop sole-
noid.

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 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 – Electrical Diagrams).
