Traction Neutral Switch - Toro Reelmaster 5010- H Service Manual

Traction Neutral Switch

The traction neutral switch is a normally open proximity
switch that closes when the traction pedal is in the neu-
tral position. The switch mounts to the pump plate on the
piston (traction) pump. The sensing element for the trac-
tion neutral switch is the traction pump lever that is se-
cured to the pump control arm (Fig. 45). The Toro
Electronic Controller (TEC) monitors the operation of
the traction neutral switch.
Testing
NOTE: Before disconnecting the traction neutral switch
for testing, the switch and its circuit wiring should be
tested as a TEC controller input with the InfoCenter Dis-
play (see Diagnostics Screen (Engine Start item) in the
InfoCenter Display section of this chapter). If the Info-
Center Display verifies that the traction neutral switch
and circuit wiring are functioning correctly, no further
neutral switch testing is necessary. If the InfoCenter Dis-
play determines that the traction neutral switch and cir-
cuit wiring are not functioning correctly, proceed with
neutral switch testing using the following steps.
1. Park the machine on a level surface, engage the
parking brake, lower the cutting units and stop the en-
gine.
2. Tilt operator seat to gain access to traction neutral
switch.
3. Turn ignition switch to the ON/PREHEAT position (do
not start engine) and check LED on cable end of traction
neutral switch.
A. Switch LED should be illuminated when the trac-
tion pedal is in the neutral position.
B. Switch LED should not be illuminated when the
traction pedal is in either the forward or reverse posi-
tion.
4. If the neutral switch LED did not function correctly:
A. Make sure that traction neutral switch is properly
adjusted (see Traction Neutral Switch in the Adjust-
ments section of this chapter). If necessary, adjust
switch and return to step 3 above.
B. Make sure ignition switch is OFF and disconnect
the traction neutral switch connector from the ma-
chine wire harness.
Electrical System
C. Using a multimeter, verify that the machine wire
harness connector terminal for black wire is closed
(continuity) to ground.
D. Turn ignition switch to the ON/PREHEAT position
(do not start engine) and verify with a multimeter that
machine wire harness connector terminal for neutral
switch pink wire has system voltage (12 VDC) pres-
ent.
E. Turn ignition switch to the OFF position.
F. If black wire is closed to ground, pink wire has
system voltage present and switch LED did not func-
tion, replace traction neutral switch. Adjust switch
during installation (see Traction Neutral Switch in the
Adjustments section of this chapter).
5. If the traction neutral switch tests correctly and a cir-
cuit problem still exists, check circuit wire harness (see
Electrical Schematic and Wire Harness Drawings in
Chapter 9 - Foldout Drawings).
6. Make sure that wire harness electrical connector is
connected to the traction neutral switch. Lower operator
seat.
