E-CART (ELECTRIC CART)

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 (5v 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

terminal down). Add more length
to this wire if necessary, and

re-terminate with a ring terminal.
