Traction Neutral Switch - Toro Reelmaster 5210 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 a bracket on the trac-
tion pump. On machines with serial numbers below
310000000 (Fig. 31), the sensing element for the trac-
tion neutral switch is a cap screw on the pump control
arm. On machines with serial numbers above
310000000 (Fig. 32), the sensing element for the trac-
tion neutral switch is the traction lever bracket that is se-
cured to the pump control arm.
Testing
1. Before testing the traction neutral switch, the switch
and its circuit wiring should be tested as an ECM input
with the Diagnostic Display (see Diagnostic Display in
the Troubleshooting section of this chapter). If the Diag-
nostic Display verifies that the traction neutral switch
and circuit wiring are functioning correctly, no further
switch testing is necessary. If the Diagnostic Display de-
termines that the traction neutral switch and circuit wir-
ing are not functioning correctly, proceed with testing
procedure.
2. Tilt operator seat to gain access to traction neutral
switch.
3. On machines with serial numbers below 310000000
(Fig. 31), test neutral switch as follows:
A. Make sure ignition switch is in the OFF position.
Disconnect the wire harness electrical connector
from the switch and check the continuity of the switch
by connecting a multimeter (ohms setting) across
the switch connector terminals.
B. There should be continuity across the switch ter-
minals when the traction pedal is in the neutral posi-
tion. There should not be continuity when the
traction pedal is in either the forward or reverse
direction.
4. On machines with serial numbers above 310000000
(Fig. 32), test neutral switch as follows:
A. Turn ignition switch to the ON position (do not
start engine) and check LED on cable end of neutral
switch. LED should be illuminated when the traction
pedal is in the neutral position. LED should not be
illuminated when the traction pedal is in either the for-
ward or reverse position.
5. If the traction neutral switch is faulty, replace switch.
Adjust switch after installation (see Traction Neutral
Switch in the Adjustments section of this chapter).

6. If the neutral switch tests correctly and a circuit prob-
lem still exists, check wire harness (see Wiring Sche-
matic and Circuit Drawings in Chapter 9 -- Electrical
Diagrams).
7. Make sure that wire harness electrical connector is
connected to the traction neutral switch. Lower operator
seat.
