Neil's FB Station Wagon

[funkyscooter]

I honestly found this video on YouTube extremely helpful in understanding how a wiper motor works, but more importantly, the roll that the switch plays in the operation of the park circuit. Up until watching this I had no clue.

From there I worked out if you briefly touch power onto the park wire the wiper goes round once and stops.

You just need to work out which wire on you switch is the park wire. Breaking your picture down of the 10 wires, a bit of a process of elimination would have me testing these wires.

Blue/white wire goes from wiper switch to BCM terminal c10.
Green wire goes from wiper switch to Intermittent wiper relay.

Brown/white wire goes from wiper switch to fuse - 12 volt power supply.
Grey/red wire goes from wiper switch to wiper motor - low speed or first speed.
Light Blue/red wire goes from wiper switch to wiper motor - high speed or 2nd speed..

Black/yellow wire goes from wiper switch to earth..
Black/green wire goes from wiper switch to Earth.

Light Blue wire goes from wiper switch to windscreen washer motor.
White/blue wire goes from wiper switch to windscreen washer motor.
Light Blue/black wire goes from wiper switch (but works on washer).

With everything connected grab a multimeter and probe these wires. With the wiper off they should read 0V, with the wiper on speed one you might see one wire briefly dip from 12+V to 0V. If you turn off the wipers this wire (and Grey/Red) will stay +12V until the cycle completes.

BUT - as there are two earths, maybe I'm leading you down the wrong path, maybe there is a different way all this works. As I said, no expert, just trial and error (and one cooked board).

Can't hurt to put a multimeter over it all and see what you find.

I am assuming a lot here regarding my set up and yours, so take the necessary precautions.

Cheers Scott
As I said before I think I’ll dummy up the setup and use say a battery charger as a power source ( I’ve done this before) so maybe less chance of torching anything and then as you say use a multi and chase the wires.
I’ll keep updates coming.

There is no need to use the intermittent unit for testing purposes , just use a wire with a 10Amp fuse in it as a test probe

Once you have it sussed then you can use the intermittent unit but i would recommend you use the unit to operate a relay that then drives the wiper motor

Thanks Blacky
At the moment when you move the VT wiper stalk to the first position nothing happens so obviously that is the intermittent position and not connected so that’s where I’ll start

So to say that today I’m a happy camper is an understatement

Now to finish welding it in and move on to more stuff

[Blacky]

Ya bloody goose ya welded it on too high !!!!


Big milestone mate - well done

[briby]

Bugger, Blacky beat me to it. To see a car that looked like a cheese grater to what it is now I'd be more than a happy camper. Great effort Neil.

Good one Neil. Eight weeks to Temora. You will piss it in.

Thanks for the comments guys
Last real major thing is replacing the top of the firewall cause the plenum and dash are toasted

One piece bumpers are pretty cool. Any bog I wonder? I’ve thought about ceramic coating chrome finish.
