Possible cause(s):
Broken wire, or loose connection,
bad motor controller.
Throttle assembly bad
Blown fuse
Broken wire, or loose connection
E-TUG-HD, Manual
Action:
Locate Pin 6 on Molex connector
at the motor controller. Try to
drive the unit in forward, there
should be 0 to 5 volts (5V is full
throttle) at this pin. If there is
voltage at pin 5, and 24 volts on
either pin 11, or 12 and the unit
does not move, the motor
controller may be bad. Consult
diagnostics page Table 2
Troubleshooting Chart; or Refer
to electrical drawing for proper
voltage readings and operation;
or Consult Factory.
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 throttle assembly, and that
there is a good ground. If there
is still no output voltage for pin 6,
or forward and reverse outputs
replace throttle assembly.
Consult diagnostics page Table 2
Troubleshooting Chart; or Refer
to electrical drawing for proper
voltage readings and operation;
or Consult Factory
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.
When replacing throttles, it may
be necessary, and does not hurt
to run a jumper wire from pin 7 to
B-.
Check the ground wire that
comes off of "B-" on the motor
controller. Re-terminate with a
ring terminal if loose.
Run jumper wire around large
diode coming off of small AGC
fuse. If this diode is bad it can
cause the unit to not move.
