Three Bars - Left Motor Wiring Trip

Check that the batteries are fully charged and
in good condition; and check all cables and
connections. Check the connections to the left
motor, look for a loose or damaged connector.
Measure the resistance from the bottom contact
of the red thick wire on the 4-pin left motor
connector to each of the top contacts of the
connector (figure 3.2.2). Measure the resistance
from the bottom contact of the black thick wire on
the 4-pin left motor connector to each of the top
contacts of the connector. If all of the readings
are open, then replace the controller. If any of the
readings are short, then replace the left motor.

Four Bars- Right Motor Disconnected

Check that the batteries are fully charged
and in good condition; and check all cables
andconnections. Check the connections to
the right motor, look for a loose or damaged
connector.
Use the meter to check the resistance across
the two bottom contacts of the thicker wires on
the 4-pin motor connector as shown in (figure
3.3.1). If the meter reads between 0 to 1.5 ohms,
then replace the controller. If none of the above
corrects the problem, replace the right motor.
