Traction Neutral Switch - Toro Reelmaster 7000-D Service Manual

Traction Neutral Switch

The traction neutral switch is closed when the traction
pedal is in the neutral position and opens when the pedal
is depressed in either direction. The switch is located on
the right side of the piston (traction) pump (Fig. 43). The
neutral switch is an input used by the Toro Electronic
Controller (TEC) to manage various machine functions.
Testing
NOTE: Make sure that traction pedal is adjusted to the
neutral position (see traction unit Operator's Manual)
before testing the traction neutral switch.
The traction neutral switch and its circuit wiring can be
tested as a TEC input using the InfoCenter Display (see
InfoCenter Display in this chapter). If testing determines
that the switch and circuit wiring are not functioning cor-
rectly, proceed with the following test procedure:
1. Park machine on a level surface, lower cutting units,
engage parking brake and stop engine. Remove key
from ignition switch.
2. Unlatch and raise hood to allow access to the piston
(traction) pump. Locate the neutral switch and discon-
nect the harness electrical connector from the neutral
switch.
3. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the switch connector
terminals.
4. Move the traction pedal to the FORWARD or RE-
VERSE position while watching the multimeter. Conti-
nuity should be broken as the switch opens.
5. Allow the traction pedal to return to the NEURTAL
position while watching the multimeter. Continuity
should be made as the switch closes.
6. If neutral switch is faulty, replace switch.

7. If the neutral switch tests correctly and a circuit prob-
lem still exists, check wire harness (see Electrical Sche-
matic and Wire Harness Drawings in Chapter 10 −
Foldout Drawings in this manual).
8. After testing is completed, connect harness electri-
cal connector to the neutral switches. Lower and secure
hood.
