Ignition Switch
The ignition switch on the console arm has three (3)
positions − OFF, ON and START (Fig. 34).The ignition
switch is an input used by the Toro Electronic Controller
(TEC) to manage various machine functions.
Testing
The ignition switch and its circuit wiring can be tested as
a TEC input using the InfoCenter Display (see InfoCen-
ter Display in this chapter). If testing determines that the
switch and circuit wiring are not functioning correctly,
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. Disassemble console arm to gain access to ignition
switch (see Console Arm Disassembly in Chapter 8 −
Chassis in this manual).
3. Disconnect wire harness electrical connector from
the ignition switch.
4. The ignition switch terminals are identified as shown
in Figure 35. With the use of a multimeter (ohms setting),
the switch functions can be tested to determine whether
continuity exists between the various terminals for each
switch position. Verify continuity between switch termi-
nals.
5. Replace switch if testing identifies that switch is
faulty.
6. If ignition switch tests correctly and circuit problem
still exists, check wire harness (see Electrical Schemat-
ics and Wire Harness Drawings in Chapter 10 − Foldout
Drawings).
7. After testing is completed, connect the wire harness
connector to the ignition switch.
8. Assemble console arm (see Console Arm in Chap-
ter 8 − Chassis in this manual).
