In low-speed operation
Check the front brusher motor
Connect the anode lead to the terminal 2 (1) from accumulator, and
the cathode lead to terminal 3, at this time, the front wiper motor
should be in low-speed operation, otherwise change the front
brusher motor.
In high-speed operation
Connect the anode lead to the terminal 1(2) from the accumulator,
and cathode lead to terminal 3, in such condition, the front wiper
motor should be in high-speed operation.
In case the operation fails to meet the requirement, change the front
wiper motor.
in operation
stop running at the stop position
a.
Run the front wiper motor at low speed and stop it at any
positions excluding the stop position by disconnect the
anode lead from the terminal 2 (1).
b.
Connect the terminals 2 and 5.\
c.
Connect the anode lead to the terminal 6 (4) from the
accumulator, and the cathode lead to terminal 3, check
whether the wiper motor parks at the stop position after
it running for another time, if the requirement is not
satisfied, change the front brusher motor.
Remark: items in parenthesis is for Dr and SF.
Rear brusher motor inspection
Connect the anode lead to the terminal 3 from the accumulator, and
the cathode lead to terminal 4, at this time, the wiper motor will be
in normal operation, disconnect the terminal 3, the rear wiper motor
should stop running at any position excluding the stop position.
