Neutral Switches - Toro Groundsmaster 7200 Service Manual

Neutral Switches

The Groundsmaster 7200 and 7210 use two (2), identi-
cal neutral switches. These neutral switches are nor-
mally open and close when the traction levers are in the
neutral locked position. The neutral switches are lo-
cated under the front panel beneath the operator seat
(Figs. 12 and 13).
The Standard Control Module (SCM) monitors the sta-
tus of the neutral switches. If the ignition switch is in the
ON position and the traction levers are both in the neu-
tral locked position, the SCM Neutral input LED should
be illuminated. The switches are connected in series so
both of the switches must be closed for the neutral input
to be completed for the SCM.
Testing
1. Before disconnecting a neutral switch for testing, the
switch and its circuit wiring should be tested as a SCM
input (see Standard Control Module in this section).
2. If the SCM verifies that the neutral switches and cir-
cuit wiring are functioning correctly, no further switch
testing is necessary.
3. If the SCM determines that the neutral switch and cir-
cuit wiring are not functioning correctly, test each neu-
tral switch as follows:
A. Make sure ignition switch is in the OFF position.
Locate neutral switches for testing.
B. Disconnect machine wire harness electrical con-
nector from the neutral switch.
C. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the connector ter-
minals.
D. When the switch plunger is extended there
should be no continuity (open) between the switch
terminals.
E. When the switch plunger is depressed, there
should be continuity (closed) between the switch ter-
minals.
F. Replace switch if necessary.
G. If the neutral switch tests correctly and a circuit
problem still exists, check wire harness (see Electri-
cal Schematics and Circuit Drawings in Chapter 8 -
Foldout Diagrams).
H. Connect machine wire harness connector to neu-
tral switch. Check neutral switch operation.
