Supervision Speed Limit Switch - Toro Workman GTX Electric & Lithium Service Manual

Supervision Speed Limit Switch

The supervision speed limit switch allows the maximum
speed of the vehicle to be set to e ither performance (16
mph/26 kph) or economy (12 mph/19 kph). The speed
limit switch is one of several inputs for the vehicle con-
troller and is located under the seat assembly (Fig. 35).
The supervision speed limit switch is open in the perfor-
mance position (key vertical) and closed in the economy
position (key rotated clockwise).
NOTE: Only speed limit switch terminals A and D are
used on the Workman GTX Electric vehicle.
NOTE: The Workman GTX Electric supervision speed
limit 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. Remove seat assembly to allow access to supervi-
sion speed limit switch.
3. Disconnect wire harness connector from the super-
vision speed limit switch.
4. With the use of a multimeter (ohms setting), the
speed limit switch functions may be tested to determine
whether continuity exists between the A and D terminals
for each switch position. The speed limit switch termi-
nals are identified as shown in Figure 36.
A. When the speed limit switch is in the performance
position (vertical), no continuity (infinite ohms)
should exist between switch terminals A and D.
B. In the economy position (key rotated clockwise),
continuity (zero ohms) should exist between switch
terminals A and D.
5. Replace the speed limit switch if testing determines
that the switch is faulty.

6. If the speed limit switch tests correctly and circuit
problem still exists, check wire harness for possible
problems (see electrical schematic and wire harness
drawing in Chapter 6 -- Electrical Drawings).
7. After speed limit switch testing is complete, plug wire
harness connector to the switch. Install seat assembly.
