Neutral Switch
Purpose
How It Works
The Neutral Switch is part of the safety circuit. The
neutral switch is used to ensure the motion control levers
are in the neutral position allowing the machine to start
(Fig. 1441).
This is a “Normally Closed (NC)” switch. The letters
“NC” will be stamped on the terminals. When the control
levers are in the neutral position, the switch is open and
there is no continuity between the switch terminals.

Location
The Neutral Switch is located in the rear, lower left side
of the control tower. It is connected to the upper switch
lever at the control linkage assembly (Fig. 1442).

Testing
Turn the ignition key to the run position (do not start
the machine). While observing the black triangle for the
Neutral indicator on the hour meter, move one of the
control levers in and out of the neutral position. If the
black triangle turns on and off, the switch is good.
If the black triangle for the neutral indicator fails to turn
on when the control lever is moved in and out of the
neutral position, the switch needs to be checked for
continuity.
1. Disconnect the switch from the wire harness.
2. With a multimeter set to the “Ohms” setting or a
continuity light, verify that there is continuity between
the terminals (plunger out).
3. With the plunger pushed in, there should be NO
continuity between the terminals.
