I have a 1976 1000, RHD. During a recent project, a green wire coming up from the harness on the wiper switch became disconnected from one of four connectors. But which one? All four connectors have a wire attached and the disconnected wire looks like it was crimped in a connector with another wire.  I've looked at the wiring diagrams but I'm still not sure. My best guess is that it goes with the black wire that leads up into the stalk. Can anyone confirm? I guess I could go connector to connector and see what happens but I didn't want to create any new issues.

When I was refurbishing my loom I found greens going all over the place, they seemed to be basically a switched-live - at certain points there were 2 or 3 all crimped together as they all just share the same origin

 

one thing I probably wouldn't do is try connecting it to the black which is quite likely a ground so as soon as you turn the key you'll short it and blow the fuse at best

[Ethel]

Are we talking loom side of the plug or on the stalk itself?

 

Solid green is a fuse protected ignition dependent live. If there's another solid green it was likely connected to that, branching +12v to other ignition dependent circuits.

 

...I should maybe read the whole post before typing?

 

The stalk arm itself is a conductor for the washer push switch. A wire is attached to the bottom end of the tube. I don't think it should be solid green, but there could be variation & the stalk needn't be original. 

 

I can't remember with certainty if it was the supply or ground, but it wouldn't be too hard to see where the other wire goes & figure it out. You can also test continuity between the tube & the connector block end of the attached wire. Is it continuous, or only when you press the stalk end?

If you have the later 2-speed wiper there should be 5 connection to motor. Green, Black, Light Green/Red, Light Green/Blue and Light Green/Green from memory.

The wiring diagrams are in the locked tgreads of this forum section.

Looking at the loom off a V reg, the plain green wire connects into the spade connector on the switch shared with a black wire, and that black wire then connects through a crimp connector to one of the black wires going to the stalk.  The other black wire to the stalk connects through a crimp connector to a green/black wire which goes straight into the loom.

I currently have my column stalks off the car. Bare shell rebuild and I will be making a new loom.

I have 99% figured out all the wiring but am stuck on a loose black wire and the washer wiring.

There is a green/black wire coming out of the washer stalk. But of course when pressing this it needs to make a circuit and one wire can’t do that on its own. So I figured that when you press the stalk it competes a circuit, the final bit of the circuit perhaps being an earth.

The loose black wire in the picture would make sense to earth to the column itself correct?

However I was confused as this is sharing a connector with a green wire which I understand to be the 12v power source to that stalk.

Where do I connect that black wire please?

And what is it that competes the circuit when I press the washer button?

Thanks in advance
Jeremy

I would buy a new column switch, rather than try to fix something that “terminal”

the black wire is the 12v supply to the washer circuit and connects to the metal tube of the wiper stalk - pressing the washer button makes the connection between the wiper stalk and the green/black wire sending 12v to the washer motor

That black wire connects to the stalk outer and is trapped when the stalk is pressed in.
It's the other connection for the screen wash motor when you press the end of the stalk.
Underneath the stalk insulating sleeve the metal tube is 12v when the ignition switch is anywhere but off.
Don't be tempted to think it's an earth wire.
Not sure how easy that would be to re-attach without removing the stalk.

Edit:-

KTS beat me too it while I was slow typing so as above with a picture

Yep, the metal tube is the earth conductor, they do fatigue, no strain relief. It's a new 'n unless you fancy getting creative.

[Straker Junior]

Thank you. Just the clarification I was looking for. Appreciated
