1. Neutral switch
The neutral switch sends signals to the Electronic Control Unit (ECU) about
the traction pedal position. The ECU takes the inputs from neutral switch and
allows the engine to start.
The neutral switch is located under the operator's platform.
1. Park the machine on a level surface, lower the cutting deck, and shut off
the engine.
2. Locate and disconnect the switch connector from the machine wire harness
(Figure 127).
3. Connect a multimeter (ohms setting) across the switch connector terminals
to check the continuity of the switch as follows:
A. When the switch plunger is extended, there should be continuity between
the switch terminals.
B. When the switch plunger is pressed, there should not be continuity
between the switch terminals.
4. Replace the switch if testing determines that the switch is damaged.
5. If the neutral switch testing is correct and a circuit problem still exists, check
the main wire harness; refer to the Electrical Schematics and Wire Harness
Drawings/Diagrams in
6. After you complete the neutral switch testing, connect the switch connector
to the machine wire harness.
