Key Switch - Toro Workman GTX Electric & Lithium Service Manual

Key Switch

The Workman GTX Electric Lithium key switch has two
(3) positions -- OFF, RUN and START. The START posi-
tion is not used on this machine. The key switch is lo-
cated on the dash. The key switch is used to energize
the SC1: Battery Controller, SC2: Traction Controller
and T: Display.
NOTE: The Workman GTX Electric key switch circuit is
a 48 VDC circuit.
Testing
CAUTION
When testing the key switch for continuity with a
multimeter (ohms setting), make sure that power
to the circuit has been disconnected.
1. Park vehicle on a level surface, turn key switch to
OFF, engage the parking brake and remove key from
the key switch.
2. Make sure that vehicle battery charger IS NOT con-
nected to electrical outlet. Open the battery circuit by
disconnecting the conductors between the battery pack
and vehicle components (see Opening Battery Circuit in
the General Information section of this chapter).
3. Raise hood to allow access to wire harness connec-
tions for switches mounted in dash.
4. Label and disconnect wire harness connectors from
the key switch.

5. Replace key switch if testing determines that the
switch is faulty.
6. If key switch tests correctly and circuit problem still
exists, check wire harness for possible problems (see
electrical schematic and wire harness drawing in Chap-
ter 6 -- Electrical Drawings).
7. After key switch testing is complete, connect wire
harness connectors to the switch.
8. Connect the conductors between the battery pack
and vehicle components (see Opening Battery Circuit in
the General Information section of this chapter). Make
sure to torque hex nuts on battery terminals from 72 to
88 in- -lb (8 to 9 N- -m).
9. Lower and secure front hood.
