• Drive the actuator motor all the way up and down using jumper wires powered by bat-

tery posive and negave. Connect them to the two actuator motor wires at the Main

Machine Controller connector. (Pink wire at connector J1 pin 4 and Gray wire at connec-

tor J1 pin 5.) Change polarity to change direcon. Immediately remove jumper wires at

the end of motor travel.

• Monitor the ohmmeter. It should show an open circuit (no connuity) only when the

actuator is in the retracted posion. In all other posions it should show a closed circuit

(connuity).

 Check the middle posion switch.

• Put the black ohmmeter lead on the Brown wire at the J2 connector pin 2.

• Put the red ohmmeter lead on the Yellow wire at the J2 connector pin 11.
