NEUTRAL SAFETY SWITCH
Purpose
Used to ensure the motion control handles are in neutral
to start the unit. It is activated by moving the motion
control handles to the neutral position (handles in the out
position).
To gain access to the neutral safety switches, the front
pocket has to be removed. There are 2 neutral switches,
one for the right motion control handle and one for the
left motion control handle (Fig. 332).

This single pole plunger (normally open) type switch
has two terminals. When the motion control handles
are in the neutral position (handles in the out position),
it pushes on the plunger, closing the contact, and
connecting the terminals (Fig. 333).
Location
1. Disconnect the switch from the wiring harness.
2. Using a VOM or test light, check rst to ensure there
is no continuity between the terminals, plunger out.
3. With the plunger pushed in, there should be
continuity between the terminals.
