Problem: Possible cause(s): Action:
Unit will not reverse; belly switch
does not function; forward ok
Broken wire, or loose connection,
bad motor controller
Bad throttle assembly
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
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. See Fig. 1
Belly switch does not function;
forward ok; reverse ok
Broken wire, or loose connection,
bad motor controller
Bad belly switch
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.
If there is still no output voltage
for pin 13, replace the switch.
Unit will not reverse. The unit only
goes forward for about 1 second
and dies when the handle is pulled
down. When the handle is re-set
and pulled down the unit will move
forward again then die.
Stuck Switch The belly switch is stuck on.
Tap the orange assembly to see
if the switch can be freed. If
this doesn’t work, disassemble
the tiller head by removing 3
screws from bottom. Slightly
loosen up the two screws that
hold the switch in place, this
may free the switch. If it is still
stuck, contact the factory for a
replacement switch.
