One Bar - Low Battery Voltage )

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

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.
Use the meter to check the resistance across the two
bottom 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.
Otherwise, check the brushes on the left motor (Figure
A3.2.1). Ensure that they are not excessively worn.
Replace as required.
