Indicator - any ideas

[trmorrisminor]

Evening all, 3 years ago I had my Morris minor van re-wired with a new wiring loom. The van is a full restoration nut and bolt rebuild, and so far its in its 7 year ( given I have very little time with a young family) . When I got the van back, I noticed the indicator light stays on when the ignition is on. The indictor wasn't one I have used before and was a spare, but it wasn't tested prior to fitting.
With a Morris Minor the light at the end of the indicator stalk only comes on when the indicator is being used, but mine stays on all the time. When you activate the indicator the bulb is still lit but you can see a very very faint/small dip in brightness as it flashes. The wiring from the indictor to the wiring loom is as follows:-
1) Black wire from indicator to black wire on loom/ bodywork.
2) Green and white on indictor to green and white on loom.
3) Green and red on indicator to green and red on loom
4) Another green and red on indictor to green and red on loom.
5) Green on indictor to green on loom and lastly
6) brown and black on indictor to purple and black on loom.

Can anyone see anything wrong with whats been done? Given there are 2 lots of green/ red wires coming from the indictor , would it make any difference if i swapped them with each other on the loom? Is it the indictor thats faulty?
Will enclose a couple of pics on next two posts, any help
Will be gratefully appreciated.

Try a different flasher unit.

I’ll second the flasher unit being faulty, giving a permanent 12V to the P (pilot) terminal.
The Light Green wire should make it’s way to the P terminal of the flasher unit.

Not something I'm familiar with, since Basil is a SII, but I'm confused as to why there are 2 G/R wires.
Unfortunately, this arrangement doesn't seem to appear in the wiring diagrams, they only offer a single version of the latter, post 63 indicators.

The Purple/Black in your loom should be for the Horn Switch.

I'm wondering if you have a Loom standard problem.

Where is your Horn Push, does it work?
If it doesn't, try a momentary earth connection onto that Purple/Black in the loom and the Horn might sound.

Even if the Horn currently does work, they might haver bodged it before they gave it back to you.....
But that Purple/Black is worrying me....

I don't understand why you have 6 wires, you only need 5.
3 for the actual indicator switch, the Feed (Green/brown) and the two outputs (Green/Red and Green/White).
2 for the lamp on the stalk end, the feed (Light Green) and the earth connection.

But, all such switches have 6 wires.... so I'm sure someone here can explain why....

Many thanks for all 3 of your inputs, will certainly check and replace the flasher unit, and thankyou to the last reply aswell. Looking at my photo and the fact that i had the van in the garage when i took note of what wire cables went to where, I am pretty sure one of the red and green wires is in fact red and brown. I am going to disconnect the purple/black and brown and black cable which is the only one that i am told is wrong and see if this makes any difference As for the horn, not sure at mo, I don't know whether the horn works or not as haven't got that far but have in the last week ordered one of the enclosed item in the photo and once installed , I should be able to test the horn then.
Will have a look at the indicator wiring, disconnect the purple/ black as mentioned above and report back. Thanks again for all your help.

It might be worth checking the other two wires are the correct way round on the flasher unit, X or B has the Darker Green wire on it and is the supply, L has the Green/Brown wire on it and is the Load output to the indicator switch. If they are connected backwards it might keep the Stalk light on.
The double Green/Red and Green/White is correct, it is separate indicator feeds to the front and rear.

The Brown/Black to Purple/Black is correct and is the horn earth return. (Brown/Black goes to the slip ring brush on the steering column).
The other Purple wire lurking in the background is interior light supply, the horn supply is also Purple and goes direct from the fuse box to the horn.
The horn might have two double terminals, make sure you connect the horn with only one connection on each double terminal, Purple/Black on one and Purple on the other.

The wiring from the indictor to the wiring loom is as follows:-
1) Black wire from indicator to black wire on loom/ bodywork.
2) Green and white on indictor to green and white on loom.
3) Green and red on indicator to green and red on loom
4) Another green and red on indictor to green and red on loom.
5) Green on indictor to green on loom and lastly
6) brown and black on indictor to purple and black on loom.

Reading this back, I've realised there's a mistake somewhere, because there should be Green/BROWN as the feed from the Flasher Unit.
There's no mention of Green/brown in your list.

Is this one Green/Brown?

I'm afraid I'd be out there with a meter working out which was which. As well as cleaning those wires to check the colours.

I am pretty sure one of the red and green wires is in fact red and brown.

Do you mean Green/Brown?

Many thanks John, really helpful info , thankyou, all makes sense what you have said. I text a friend yesterday who has a minor and his has the following wires (please see enclosed pic ) on his traveller, which is a 1971 same as my van. His is a lucas flasher unit and I have a ESM one ( pic is the spare flasher unit i have at home, as van is at my dsds house) , can you confirm your wires are the same? But am guessing the light green wire and dark green wire is live in and out?The ESM flasher unit has the letters L, X, P next to each terminal, based on the same configuration on my friends lucas unit I am guessing brown/green should be on X and then I am guessing what your suggesting is green should be on P and L, but they maybe on the wrong way round so to swap one green currently on the L to P and visa versa, is that your suggestion? Very grateful for all your help.

Just to confirm,
Green/ Brown goes to L.
Darker Green goes to X.
Light Green goes to P.

The wiring on your stalk under the dash is correct.

Don’t know how, but Berni has miss quoted me with one of your posts

Regards John.

Not my quote Berni

Sorry about that, the perils of trying to make multiple quotes in a post.

I am pretty sure one of the red and green wires is in fact red and brown.

What I don't understand in all this, for the stalk with the tell-tale lamp, is the purpose of the

brown and black on indictor to purple and black on loom.

Where is that from?
What's it for?

[trmorrisminor]

John that is brilliant thankyou for all your help, thats a huge help.Looking at your info my friends wiring its seems the wires are on different terminals, are you using the same as me and using the ESM ones? Do you think the lucas flasher units use the same setup in terms of wire configuration or are they totally different hence my friends colour of wire setup? Am at my dads tomorrow so will look at this when i get there to check that A) the 2 x green wires and 1x green/ brown are attached to the flasher unit ( incase a bodge has been done and old random wire has been located to flasher unit and b) to see if the configuration/ location of the wires bares any resemblance to what you have kindly told me.
Will report back tomorrow and thankyou .

In your photo 2, I think the purple/black should be disconnected from the brown/black and re-attached to the stray purple/black bullet connector poking upwards in the background...

No it doesn't, please don't. The Purple/ Black is the earth return from the horn and stays all by itself with the Brown/Black.
Read my previous posts, and check the wiring diagram.
Of course if the wiring diagram is wrong then it will need further investigation.

I've just re-read Chippers post, I am sure the wire in the background is/should be a single colour Purple

It looks like your modern and old flasher unit in your friends traveller have the X and L in opposite positions, so connect it as I have described.

Regards John.

[trmorrisminor]

Ok many thanks John, just going by the previous comment my brown and black from the indicator is connected to the black and purple on the wiring loom, given there is another black and purple in the background ( which you can see in the pic) would these work in the same way if connected or is it possible the back and brown has been put in the wrong black and purple wire? I am asking all these questions as when i go to dads tomorrow and should it turn out that the wires into the flasher unit are all correct, atleast i have some other possibilities to look at as I am desperate to get this long running issue sorted tomorrow.
Many thanks
Richard

Ok thanks John, will use your suggestion on wires into the flasher unit than my friends. As you say sounds like lucas and esm have slightly different configurations on their terminals.
