Rear Wiper Motor

1. TESTING WIPER MOTOR
As shown, use a 12 V battery (1) to connect its (+) ("Red" lead wire (3)) and (-) terminals to terminal "D" and "Black" lead wire (4) respectively. Then motor (2) should rotate at 35 to 45 rpm.




2. TESTING AUTOMATIC STOP ACTION
a. First, connect battery (+) terminal ("Red" lead wire (3)) to terminal "D" and battery (-) terminal to "Black" lead wire (4) and let the motor (2) turn.
b. Then disconnect terminal "D" from battery (1) and let the motor (2) stop.
c. Next connect terminal "D" and terminal "A" with a jumper wire (5) and connect terminal "B" to battery (+) terminal. Observe the wiper motor (2) turns once again, then stops at a given position.
d. Repeat these steps several times, and inspect if the motor (2) stops at the given position every time.
