Accelerator Switch
The accelerator switch is a four terminal, two circuit
switch. When the accelerator pedal is pushed, the
switch allows current flow to the start/run solenoid, hour
meter, and engine oil indicator and provides an open cir-
cuit to the engine ignition system. With the accelerator
pedal released, the switch provides a grounding circuit
for the engine ignition system and prevents current flow
to the start/run solenoid, hour meter, and engine oil indi-
cator.

After switch adjustment, make sure that the engine
starter does not engage when the parking brake is en-

and the body of the switch slightly.
