er solenoid is de–energized. The diode plugs into the
wiring harness.

RPM Shutdown Module (Workman 2100/2110)
The RPM shutdown module allows the engine to contin-
ue running briefly after the accelerator pedal is released
and the vehicle is decelerating. The module monitors
engine speed at the engine stop switch terminal.
Through the RPM shutdown module, the engine ignition
system is not grounded until the engine speed has
slowed to approximately 1300 RPM. By allowing the en-
gine to continue running briefly during vehicle decelera-
tion, better vehicle performance can be achieved.

Start engine and monitor engine speed with a
tachometer. Press the accelerator pedal to raise engine
speed briefly and then release pedal while watching
tachometer and spark tester. When engine speed de-
creases to approximately 1300 RPM, spark tester
should register no spark and the engine should stop.
