Wiper Motor
1) As illustrated, use a 12 V battery to connect its (+) terminal to ter-
minal ªAº, and its (±) terminal to Black lead wire (2) (Type A, B)
or terminal ªEº (Type C).
If motor (1) rotates at a low revolution speed of 45 to 55 rpm, it
is proper. For high speed check, connect battery (+) terminal to
terminal ªBº, and its (±) terminal to Black lead wire (2) (Type A,
B) or terminal ªEº (Type C). If motor rotates at a high revolution
speed of 67 to 83 rpm, it is proper.
