VR2 Controller Diagnostics Codes (cont.)
Check that the batteries are fully charged and in good
condition; and check all cables and
connections. 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.
Otherwise, check the brushes on the right motor (Figure
3.3.2). Ensure that they are not excessively worn.
Replace as required.
