Hi/Low (Transport/Mow) Switch - Toro Reelmaster 7000-D Service Manual

HI/LOW (Transport/Mow) Switch

The HI/LOW (transport/mow) switch is a normally open
proximity switch that closes when the speed limiter is
placed in the HI (transport) position. The switch mounts
to a bracket on the footrest platform. The sensing plate
for the HI/LOW (transport/mow) switch is the mow
speed limiter. The HI/LOW (transport/mow) switch is an
input used by the Toro Electronic Controller (TEC) to
manage various machine functions.
Testing
The HI/LOW (transport/mow) switch and its circuit wir-
ing can be tested as a TEC input using the InfoCenter
Display (see InfoCenter Display in this chapter). If test-
ing determines that the switch and circuit wiring are not
functioning correctly, proceed with the following test pro-
cedure:
1. Park machine on a level surface, lower cutting units,
engage parking brake and stop engine.
2. Turn ignition switch to the ON position (do not start
engine) and check LED on the cable end of (transport/
mow) switch (Fig. 46). The LED should be illuminated
when the speed limiter is in the HIGH (transport) speed
position. The LED should not be illuminated when the
limiter is in the LOW (mow) position.
3. If the HI/LOW (transport/mow) switch LED did not
function correctly:
A. Make sure that the HIGH/LOW switch is properly
adjusted (see HIGH/LOW (transport/mow) Switch in
this chapter). If necessary, adjust switch and retest.
B. Make sure ignition switch is OFF and disconnect
the HI/LOW switch from machine wire harness.
C. Verify that the machine wire harness connector
terminal for black wire is closed (continuity) to
ground.
D. Turn ignition switch to the ON position (do not
start engine) and verify with a multimeter that ma-
chine wire harness connector terminal for pink wire
has system voltage (12 VDC) present.
4. If black wire is closed to ground, pink wire has system
voltage present and switch LED did not function as de-
sired, replace HI/LOW switch. Adjust switch after instal-
lation (see HIGH/LOW (transport/mow) Switch in this
chapter).

5. If the HI/LOW switch tests correctly and a circuit
problem still exists, check yellow output wire continuity
between HIGH/LOW switch connector and TEC con-
nector (see Electrical Schematic and Wire Harness
Drawings in Chapter 10 − Foldout Drawings in this man-
ual).
6. Make sure that HI/LOW switch is connected to wire
harness when testing is complete.
