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. 13 and 14).
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.

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.
