410 windscreen washers

[livermoreb]

Thanks Alexander. I agree it is a bit complicated. I have tried to amend my description to give a more comprehensive explanation below:-

The 411 diagram shows a green wire going from the switch to the motor and a black wire going to earth/ground. My motor has a green wire from the switch to the + terminal and a black and green one on the other.

The washer is not working so to test it I disconnected both wires from the motor and connected one of the terminals on the motor direct to earth and the other direct to the + side of the battery. Hey presto it worked so the problem is not the motor.

I then disconnected the wire I had put on the earth terminal on the motor and reconnected the black and green wire to it and kept the terminal on the motor marked + directly connected to the + terminal on the battery and it did not work.

From this I concluded that the earth was at fault so connected the black and green terminal on the motor directly to earth again, disconnected the wire from the + terminal on the battery and reconnected the green wire to the + terminal on the motor. When I turned on the ignition to test if it now worked, the washer sprang into life and would not stop!

I hope this makes it clearer.
