Accelerator Switch
The accelerator switch is a four terminal, two circuit
switch that is located on the control pedal frame (Fig.

37).
The Workman MDE uses only one of the switch cir-

cuits (terminals 3 and 4). When the accelerator pedal is
depressed, the switch allows a closed circuit (input) for
the controller to allow traction motor operation. When
theacceleratorpedalisreleased,theswitchprovidesan
open circuit (no input) for the controller to prevent trac-
tion motor operation.

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-
