The key switch ( Figure 237 ) is located on the control arm and has three positions:
O
FF
, R
UN
, and S
TART
( Figure 238 ).
The Toro Electronic Controller (TEC) monitors the operation of the key switch.
Testing the Key Switch
1. Park the machine on a level surface, lower the cutting units, set the parking
brake, and shut off the engine. Remove the key from the key switch.
2. Before you disconnect the key switch for testing, ensure that you test the
switch and its circuit wiring as a TEC electrical input with the InfoCenter
display; refer to
Using the InfoCenter Display for Troubleshooting (page
7–28) .
3. If the input testing verifies that the key switch and circuit wiring are functioning
correctly, no further key switch testing is necessary.
4. If the input testing determines that the key switch and circuit wiring are not
functioning correctly, proceed with the following key switch testing procedure.
5. Remove the right control arm cover to get access to the key switch; refer to
Disassembling the Control Arm (page 8–23) .
6. Ensure that the key switch is in the O
FF
position. Disconnect the wire harness
connector from the key switch.
7. The key switch terminals are identified in Figure 238 and the circuitry of the
switch is shown in the Circuit Logic Table (page 7–65) . With the use of a
multimeter (ohms setting), test the switch functions to determine if continuity
exists between the various terminals for each switch position. Check the
continuity between the switch terminals.
