WASHER LINKED OPERATION
INSPECTION
1) Disconnect negative cable at battery.
2) Disconnect combination switch lead wire coupler.
3) Make sure that front wiper switch is at OFF position.
4) Connect battery positive terminal to terminal “N” and battery
negative terminal to terminal “R”.
5) Connect voltmeter positive lead to terminal “O” and negative
lead to terminal “R”.
6) Push washer switch and check that voltage changes as shown
in the diagram.

FRONT WIPER MOTOR
INSPECTION
1) As illustrated left, have a 12V battery and connect its (+) termi-
nal to terminal “A”, and its (–) terminal to bracket (1) (wiper
ground). If motor (2) rotates at a low revolution speed of 45 to
55 rpm, it is proper. As for high speed check, connect battery (+)
terminal to terminal “B”, and its (–) terminal to bracket (1) (wiper
ground). If motor (2) rotates at a high revolution speed of 67 to
83 rpm, it is proper.
2) Testing automatic stop action
a) Connect 12V battery (+) terminal to terminal “A” of wiper mo-
tor (2) and (–) terminal to bracket (1) (wiper ground) and let
the motor turn.
b) Disconnect terminal “A” from battery, and let the motor stop.
c) Connect terminal “A” and “D” with a jumper wire (3), and con-
nect terminal “C” to battery (+) terminal. Observe the motor
turns once again then stops at a given position.
d) Repeat a) thru c) several times and inspect if the motor stops
at the given position every time.
