The controller is located under the right lower corner of the control panel
141).
Note: Refer to the Electrical Schematics in
troubleshooting the glow controller circuit.
1. When the key switch is turned to the RUN position, the controller energizes
the glow plugs and lights up the glow lamp for approximately 6 seconds.
2. When the key switch is held in the START position, the glow plugs will
