Locate Pin 11 on Molex connector at
the motor controller. Try to drive
the unit in forward; there should
be 24 volts at this pin. If there is
voltage and the unit does not
move, the motor controller may be
bad, consult diagnostics
page/factory. If there is no
voltage, trace the wiring back
towards the tiller head and check
voltage on each side of
connectors. Continue this until
bad connection is found.
If the connections are all good, and
there is no voltage coming out of
throttle assembly, then the
throttle assembly may be bad.
Verify there is 24 volts going into
the assembly and that there is a
good ground. If there is still no
output voltage for pin 11, replace
throttle assembly. See Fig. 1
Locate Pin 12 on Molex connector at
the motor controller. Try to drive
the unit in reverse; there should
be 24 volts at this pin. If there is
voltage and the unit does not
move, the motor controller may be
bad, consult diagnostics
page/factory. If there is no
voltage, trace the wiring back
towards the tiller head and check
voltage on each side of

Locate Pin 13 on Molex connector at
the motor controller. Try to drive
the unit in reverse, and hit the
belly switch... there should be 24
volts at this pin. If there is
voltage and the unit does not
move, the motor controller may be
bad, consult diagnostics
page/factory. If there is no
voltage, trace the wiring back
towards the tiller head and check
voltage, or continuity on each side
of connectors. Continue this until
bad connection is found.
If the connections are all good, and
there is no voltage, then the
switch may be bad. Verify there
is 24 volts going into the switch.
