Accelerator Switch
The accelerator switch is a four terminal, two circuit
switch that is located on the control pedal frame (Fig.
2
38).
The Workman e2050 and e2065 use only one of the
3
1
switch circuits (terminals 3 and 4). When the accelerator
pedal is depressed, the switch allows a closed circuit (in-
put) for the controller to allow traction motor operation.
When the accelerator pedal is released, the switch pro-
vides an open circuit (no input) for the controller to pre-
vent traction motor operation.

With the use of a multimeter (ohms setting), the
switch functions may be tested to determine whether
continuity exists between the switch terminals for both
switch positions. Verify continuity between switch termi-
nals using the following table:

When reconnecting wiring harness connector to
switch after testing, harness connector and switch ter-
minal area should be filled with dielectric gel (see Spe-
cial Tools) to prevent corrosion of connection terminals.
Apply gel fully to both harness connector and switch ter-
minal area, plug harness connector into switch to distrib-
ute gel, unplug harness connector, reapply gel to both
surfaces and replug harness connector into switch.
