Problem: Possible cause(s): Action:
Unit will not reverse; belly switch
does not function; forward ok
Broken wire, or loose connection,
bad throttle assembly, bad motor
controller.
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 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 12, replace
throttle assembly.
