Traction Neutral Switches
The Sand Pro 2040Z use two (2), identical traction neut-
ral switches. These switches are normally open and
close when the motion control handles are in the neutral
locked position. The neutral switches are attached to the
motion control bracket at the lower end of the motion
control handle assembly (Fig. 17).
Testing
1. Before removing the traction neutral switch for test-
ing, the switch and its circuit wiring should be tested with
the Hour Meter Module (see Hour Meter Module in this
chapter). If the Hour Meter Module verifies that the neut-
ral switch and circuit wiring are functioning correctly, no
further switch testing is necessary. I f, however, the Hour
Meter Module determines that the neutral switch and cir-
cuit wiring are not functioning correctly, proceed with
traction neutral switch testing.
NOTE: Both of the traction neutral switches have to be
closed (both motion control handles placed in the neu-
tral locked position) in order for the hour meter module
neutral indicator to be illuminated.
2. Make sure ignition switch is OFF. Remove key from
ignition switch.
3. Remove control cover to access traction neutral
switch that is to be tested (Fig. 19).
4. Locate neutral switch and disconnect machine wire
harness connector from the neutral switch that is to be
tested.
5. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the connector termi-
nals.
6. When the neutral switch plunger is depressed, there
should be continuity (zero resistance) between the
switch terminals.
7. When the neutral switch plunger is extended, there
should be no continuity (infinite resistance) between
the switch terminals.
8. Replace traction neutral switch if testing determines
that it is faulty. If the neutral switch tests correctly and a
circuit problem still exists, check wire harness (see Elec-
trical Schematic and Wire Harness Drawing in Chapter
7 - Electrical Drawings).
9. Connect machine wire harness connector to the
neutral switch after testing. Secure control cover to ma-
chine with removed fasteners.
