Problem: Possible cause(s): Action:
Unit will not go forward, or reverse,
but belly switch still functions
properly.
Broken wire, or loose connection,
bad motor controller,
Throttle assembly bad
Locate Pin 6 on Molex connector at
the motor controller. Try to drive
the unit in forward, there should
be 0 to 5 volts (5 v is full throttle)
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 6, replace
throttle assembly. See Fig. 1
Unit will not move forward, or
reverse, and the Belly switch will
not function, unit does turn on as
indicated by the battery gage
lighting up.
Blown fuse
Broken wire, or loose connection Verify fuses are good, replace if
blown.
Locate Pin 7 on Molex connector at
the motor controller. Trace wire
back up to tiller head and verify
continuity all the way to the
throttle assembly. Repair any
loose connections.
If there is continuity up to the
throttle assembly, then check the
ground wire that comes off of B-
on the motor controller (3
rd
terminal down). Add more length
to this wire if necessary, and
re-terminate with a ring terminal.
Unit will not go forward; the belly
switch functions; reverse works.
Broken wire, or loose connection,
bad motor controller
Bad throttle assembly
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
