Identify this wire


Recommended Posts

Well, black would normally be earth so if it goes to the relay and is not attached to the body then you have no circuit. Is there a lucar tag welded to the body nearby that has come adrift?

The first picture is an earth wire which would normally go to an earth tag spot welded to the body by the battery hold down bracket.

Do you know what earth it would be for?

Its part of the entire earth system there are several around the body.Including down the front by the headlamps and in the boot, it should be connected to the tag pictured in my previous post.

Is there not a fly lead from the column rubber coupling top bolt to one on the bottom of the coupling to create an earth for the column? I can’t see it in the photo.

My 4a has one but maybe the changed the earthing system on the TR6.

There should be on all 4/4a/5/6 a link across the column doughnuts. for horn earth plus one for the rack to earth on the chassis too. Also missing a locking wire on two out of four bolts.

I'm pretty sure I have that earth wire just sitting there like yours, I've never worried about it as all the electrics seem to work fine.  I too never knew what it was for.

I echo Gareth’s comments. I was surprised when I came across it, but everything works fine with or without it attached.

Thats because there are several other earth points round the loom and they are all interconnected.

Some built in redundancy is good for the electrics, might see if I can add it back in.

You want something like the connector that bolts on a coil and gives a spade connector you could then clean up the area and rivet it down. Or solder if you could get it hot enough.
