INSPECT DRIVER'S HEIGHT ADJUSTABLE ANCHOR MOTOR AND SENSOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 1, and check that the slider moves upward.
b. Reverse the polarity and check that the slider moves downward.
If operation is not as specified, replace the height adjustable anchor motor.

INSPECT DRIVER'S HEIGHT ADJUSTABLE ANCHOR MOTOR AND SENSOR PTC THERMISTOR OPERATION
Inspection using an ammeter:




a. Connect the positive (+) lead from the battery to terminal 1, the positive (+) lead from the ammeter to terminal 4, and the negative (-) lead to battery negative (-) terminal, then move the slider to end position.
b. Continue to apply voltage and check the current changes to less than 0.1 A within 6 to 46 seconds.




c. Disconnect the leads from terminals.
d. Approximately 60 seconds later, connect the positive (+) lead from battery to terminal 4 and the negative (-) lead to terminal 1, and check that the slider moves to the opposite side.
If operation is not as specified, replace the height adjustable anchor motor.

Inspection using an ammeter with a current-measuring probe:




a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 4.
b. Attach a current-measuring probe to the negative (-) lead, and move the slider to the end position.
c. Check the current changes to less than 0.1 A with 6 to 46 seconds.




d. Disconnect the leads from terminals.
e. Approximately 60 seconds later, reverse the polarity, and check that the slider moves to he opposite side.
If operation is not as specified, replace the height adjustable anchor motor.
