Neutral switch
A neutral switch as part of the machine interlock system (
). The neutral
switch is part of the transmission/pump control arm assembly. When either
motion control pedal is pressed, the switch is allowed to return to its normally
open condition. The control arm assembly presses the switch plunger when
either traction pedal is released, returning the transmission to neutral and closing
the switch. The interlock module monitors the position of the neutral switch
(open or closed). Using inputs from the neutral switch and other switches in
the interlock system, the interlock module opens or closes the engine ignition
circuit (controls circuit ground).
Note:
Check the motion control linkage operation before testing the switch; refer
to
Adjusting the Control Pedal Return to Neutral Mechanism (page 5–29)
.
Testing the Neutral Switch
1. Park the machine on a level surface, engage the parking brake, and shut off
the engine.
2. Disconnect the wire harness connector from the neutral switch.
3. Check the wire harness connector for corrosion and clean the connector
if necessary.
4. Use a multimeter (ohms setting) and test the switch. The switch is closed
(continuity exists between the terminals) when both the motion control
pedals are in the N
EUTRAL
(rearward) position, and open (no continuity
exists between the terminals) when either motion control pedal is in a M
OVE
(forward) position.
5. Replace the neutral switch if testing determines that it is damaged.
6. If the neutral switch testing is correct and a circuit problem still exists, check
the wire harness for the circuit continuity; refer to the
and Wire Harness Drawings/Diagrams (page 6–3)
.
7. After testing, apply a film of dielectric grease to the switch terminals and
connect the machine wire harness connector to the neutral switch.
