1. Neutral switch
2. Floor plate
The neutral switch is a normally open proximity switch that closes when the
traction pedal is in the neutral position. The neutral switch is located under the
floor plate (Figure 115).
The Standard Control Module (SCM) monitors the position of the neutral switch
(open or closed). Using inputs from the neutral switch and other switches in the
interlock system, the SCM controls the energizing of the engine start relay, and
the fuel stop solenoid and fuel pump.
1. Park machine on level surface, lower cutting units, stop engine, apply parking
brake and remove key from key switch.
2. Make sure the neutral switch is properly adjusted (see
6–5)).
3. Before disconnecting the switch for testing, the switch and its circuit wiring
should be tested as a SCM input. (see
(page 6–45)). If input testing verifies that the switch and circuit wiring are
functioning correctly, no further switch testing is necessary. If, however,
input testing determines that the switch and circuit wiring are not functioning
correctly, proceed with the following switch testing procedure.
4. Make sure key switch is in the OFF position. Disconnect electrical connector
from the neutral switch.
5. Check the continuity of the switch by connecting a multimeter (ohms setting)
across the connector terminals.
