（5）Inspection of the operation of the front washer 

As shown in the figure, the terminals 8 and 5 are respectively connected to the positive 

and negative pole (anode and cathode) of the secondary cell, and the positive and 

negative probes of a voltmeter are respectively connected to the terminals 7 and 5. Turn 

on the washer switch, check up if the voltage changes as follows: after the washer switch 

was turned on for one second, the volt meter displays the supply voltage, and after 

turning off for 3 seconds, 0 voltage is displayed. If it is not the case, the wiper and 

washer switch should be replaced.

（6）Inspection of the performance of the front wiper motor 

 

The circuit arrangement is shown in the figure. Inspect the low speed performance of the 

front wiper motor, and replace it if necessary. It should be noted that the inspection 

should be accomplished as soon as possible, in order to prevent overheat (overburning) 

of the motor.
