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.

If the reading is short (resistance is less than

10 K ohms) on any of the readings, proceed to

check the 4-pin motor connector. Measure the

resistance from the bottom contact of the red

thick wire on the 4-pin right motor connector to

each of the top contacts of the connectors see

(figure 3.3.3). Measure the resistance from the

bottom contact of the black thick wire on the 4-pin

right motor connector to each the top contacts of

the connector (below right). If all of the readings

are open, then replace the controller. If any of the

readings are short, then replace the right motor.
