3.1 One Bar - Low Battery Voltage )

This code could indicate discharged batteries, failed batteries, or poor battery connections. Begin by recharging the bat-
teries and then refer to Section 1 to check batteries and connections.

3.2 Two Bars - Left Motor Disconnected

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.
Otherwise, check the brushes on the left motor. Ensure
that they are not excessively worn, (replace as required) as
shown in (Figure A3.2.1).
Use the meter to check the resistance across the two bot-
tom contacts (thicker wires) on the 4-pin motor connector
as shown in (figure A3.2.2). If the meter reads between
0 to 1.5 ohms, then replace the controller. If none of the
above corrects the problem, replace the left motor.
If the meter reads between 0 to 1.5 ohms, then replace the controller.
If none of the above corrects the problem, replace the left motor.
