Triumph TR6 - wire from ingnition key barrel???

I was mucking about underneath the dashing installing new wiper spindle seals and i notice a broken wire which I think comes from the side of the key barrel. I think it may have come from the top of the plasticl square on the side of the barrel. I can't see this lead picture in the TRF catalog or the triumph factory repair manual. Any idea what it is and can it be replaced. Thanks

DPO??

Just a thought, was that to a radio?
Don Kelly

May be but don't think so Don.. That plastic piece look integral to the key barrel. Anything similar on your vehicle mine is 71 tr.
A Vandergoot

Oh, it comes off that plastic piece?

If it was stock and the wire looks too thick ,Green is for power on with the key in run, and none come off the iggy switch
Don Kelly

Yup I think it comes off the plastic piece. Yeah it is still stock. With the wire disconnected from there it doesn't seem to make any difference I'll just leave it off for now! At least until I get the rest of the wiring sorted.

According to a wiring diagram I have for a 70-71, the black/green wire is part of the ign. key warning circuit. I think it activates a buzzer if the key is left in the ign. switch and the door is opened. Real important stuff.

Berry , I'll be danged . That is B/G I just thought it was green
Don't think mine had that.
In fact I had to buy the buzzer from someone so I could put it on my fuel pump circuit
Don Kelly

Don-It solved a mystery for me. I wondered what the buzzer was for. Long ago, I moved the ign. to the dash and got rid of the steering lock.

Blasphemy! A hole has been drilled in the sacred dash.
I put my ign. swith in the plinth, like the early cars.

Berry,
And why did you wait until puberty to acquire this bad habit??

Well gentlemen speaking of wires maybe you can identify these. They are white/purple,purple and black I suspect they are for the right hand door switches but any chance you could tell me where to find the wires to connect to it? Are they usually hidden under the carpet somewhere? These wires run along the side of the driver side foot well. Thanks

Also any idea what the black box is in the picture looks like some kind of relay. It is always hot though. I think it maybe for the hazard signal. Thanks again guys.

A Vandergoot

Hello guys,
I've also moved the ignition to the TR-5 position , got rid of the steering lock and all the bother trying to find the key hole. Never regretted it.

I think Don hit the proverbial nail...

DPO

It is a relay but what it is for?? Disconnect it and see what does not.

I also have a 71. I disconnected that stupid noise way back on day 1.

You are correct. The purple is the supply side to both door switches,the tranny tunnel lamp, and the boot lamp and switch. The wiring harness as you say travels down the left side of the car. The harness has a big disconnect ( a Molex connector) behind the driver side left hand kick panel. So this is where this purple wire is located. The purple white is on the other side of the lamp and switches.

A, Do you have a wiring schematic? This is very helpful in tracing wires from start to finish as the wire colour can change in the circuit (as it does here).

If you do not have one, http://www.vitessesteve.co.uk/contents_page.htm

Thanks Rick I do have a schematic but I find it a bit difficult to use. As far as things working the head lights work the front hazard flashers work but no turn signals brake lights or running lights. But the engine starts and the battery stays charged.
The relay pictured I think has to do with the flashers but there is hot terminal and it is not dependent on the ignition being on. I have green wire not attached that looks to be grounded that should be attached I think, but when I do the flashers stop working and the relay gets hot so I'm wondering if I'm on the right track here. I have removed a bunch of wire that was part of an old radio install.
A Vandergoot

You need this Schematic

Don Kelly

Being that I didn't have this when I got mine.
Let me see if I understand how this works.
When the key is in the iggy, it must push a metal tab to make contact with the G/B wire which then creates the circuit to the buzzer and the buzzer getting power from a purple wire?

Is this sound plausible?
Don Kelly

I am sorry to hear you do not find the schematic helpful. My link was to an old schematic but Don's is in technicolour. This helps in following (tracing) a schematic and to identify the wire colour. You have to look at the colour legend down in the lower R corner as the letter is not necessarily the colour of the wire eg. black is B and brown is N.

I say all this because you have given a bunch of different colour wires that you question what they are.
Schematics IMHO are very easy to follow once you get use to them and understand what the symbols mean.

You mention the Green wire being attached to ground. This is a big no no. Green is a power supply to a circuit not ground. You can tell this because Green comes from a fuse. Black is the ONLY colour that should be connected to any ground source. No wounder the relay gets hot:)

A question for you A. Do you have overdrive? That yellow wire is looking familiar.

Don again you hit the nail on the head. The LH (driver side) door switch is a double switch where the two switches are independent of each other (they are wired separately). The circuit for the buzzer is ONLY closed when 2 things happen. Key is in the ignition and the door is open. Note the foot well lamp operates when the door is open.

Foot well lamp?
What's that?
