3C1 CONTACT COIL AND COMBINATION SWITCH ASSEMBLY.
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.

2) Testing automatic stop action.
a) Connect 12 V battery (+) terminal to terminal ªAº of wiper mo-
tor (1) and (±) terminal to Black lead wire (2) (Type A, B) or
terminal ªEº (Type C), and let the motor turn.
b) Disconnect terminal ªAº from battery, and let the motor stop.
c) Connect terminal ªAº and ªDº with a jumper wire (3), and con-
nect terminal ªCº 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.
Washer Pump
Connect battery (+) and (±) terminals to pump (+) and (±) terminals
respectively to check pumping rate.
Check for both front (3) and rear (2) (if equipped) washer pump.
Pumping Rate:
Front and Rear (if equipped) more than 1.0 l / min.
(2.1 US pt. / min.,
1.76 lmp pt. / min.).

Intermittent Wiper Relay Circuit
1) Disconnect negative cable at battery.
2) Disconnect combination switch lead wire coupler.
3) Turn the front wiper switch to INT position.
4) Turn the intermittent time control switch to FAST position.
5) Connect battery positive terminal to terminal ªB3º and battery
negative terminal to terminal ªEº.
6) Connect voltmeter positive lead to terminal ª+1º and negative
lead to terminal ªEº.
Check that the voltmeter indicates the battery voltage (10 ±
14 V).
7) Connect terminal ªAsº and terminal ªB3º by a jumper wire. Then
move jumper wire end connected to terminal ªB3º to terminal ªEº.
Observe the voltmeter voltage drops to 0 V right after connecting
the jumper wire from terminal ªB3º to ªEº. Then the voltage rises
to battery voltage (10 ± 14 V) within the time shown in the table
below.
