MG MG Y Type - turn signal relays

Dear all, can anyone upload an image of the YT turn signal relays in situ? Tom
Thomas McNamara

Hi Tom, I am not aware of any relays in the wiring of YT's.

Can you explain more clearly what you need, and I will be happy to assist where I can.

Cheers

Tony,
I think Tom is referring to the Relays that were on the EXU saloons in the US and he wants to duplicate this on his YT which according to his Wiring Dilemma thread, his EXR YT had/has an unusual wiring harness.

Can someone post a photo showing the location of their relays in their YA/B saloon.

Tony, slightly off topic - can you post a photo of where you placed your L & R flasher units, as per your article on the IMGYTR website.

Dear all, I am the recipient of conflicting information concerning the YT turn signal relays. As now understood, YT's exported to the USA were required to have turn signal indicators? My YT never had any as far as I can tell. When the dumb current owner, (that's me), inadvertently smoked the wiring harness I found it impossible to locate the correct diagram that fit the car.

I decided to go with a different loom, containing signal light wiring, to "upgrade" the safety factor. This diagram is Lucas No. W76361.

Now, if I understand correctly, the YT's did not have signal lights and/or relays to support them? The current issue is finding someone to create the harness to match the diagram.

Ain't it fun? All hail the internet. :) Thanks to all, Tom

Attached please find photo of the relays "hidden" behind the dash in the vicinity of the steering collumn. The relais is located in the centre of the picture (with three spade connectors). Since I am using LED bulbs, it is rather black than the familiar silver tube.

My YT also never had indicators, thus I ordered a new, tailor made wiring harness from AutoSparks in UK (they are the best)!
I'll send an additional mail showing the upgraded wiring harness drawing.

Anton, once again you come through! THANK YOU! Just what I need. Be well, Tom

The reason your car was NOT fitted with relays is because it is an EXR car. Relays are only necessary if you have added rear (and/or) front flashing lights. The EXU had flashing turn signals flared into the rear of the wings/fenders so required relays in it's wiring.

Both the EXR and the EXU were exported to North America and most EXRs that are in the US now found their way into the US over the border from Canada. It is all very confusing I know if you believe your car to have been originally exported to the US as some EXRs also were dispatched direct to the US too!

Hope that adds to your confusion LOL ... or helps :)!

Are we talking about relays here or flasher cans - two different animals in my mind ?.
A L SLATTERY

Same thing arent they Tony? You need a relay/can to make the turn lights flash.

Either way, the EXR and EXL cars do not need them only the EXU ... right?

Paul
Paul Barrow

A relay is a two part switch - a low voltage is used to trigger the connection of another circuit, it's either on or off.

A flasher can has a bi-metallic switch (in primitive form) that switches a circuit on, then off, then on again.

In my YT with flashing indicatorsn and my YA with flashing indicators and trafficators, the flasher cars are installed behind the dash panel on the steering column and are wired from the slip ring connectors and back again. with a small loom I made.

It would appear in your wiring diagram that you are not using the steering column Slip ring. How are you you activating the indicators and horn?

A PO installed a stem indicator switch and flasher unit and had a partial trafficator sitting in the steering wheel when I bought the YT. Paul has rebuilt the trafficator and I and in the process of wiring it in.

I am thinking of keeping the stem indicator switch for use at traffic lights where the queue if long and the trafficator will time out before I turn.

My query - is it possible to run both indicator systems through the same flasher unit and lights or should I just run the trafficator and remove the indicator stem.

cheers

I used a Slipring on my YT together with the horn push indicator unit of a saloon. The according little harness (shown in the photograph is not shown in the wiring diagram because it has to be ordered separately (also from NTG?).
You might note the round silver coloured clamp at the top left corner of the picture. It serves to position the long steering column, thus minimising any strain on the "fragile" slip ring, The round clamp was copied from a friend's TD....

all the best
Anton

Anton Piller

Anton, thank you for your reply.

My YT has what looks like original correct colour y wiring inside the steering column.

I have determined that using both indicator stem and steering wheel trafficator is not electrically feasible, I will therefore disconnect/isolate the stem wiring and wire in the trafficator.

Anton, did you wire in a dash light to let you know when the indicators were on? (My hearing is not the best and in an open car with traffic I probably not hear the blinker unit ticking away)

cheers

Good idea to do away with the indicator stem. The trafficator switch is sufficient in cojunction with a dash warning light and a little buzzer mounted behind the dash that generates the same sound as if you would forget to buckle up. The buzzer generates an intermitted sound because it is also activated by the flasher unit.
If the queue in front of a traffic light is too long and the trafficator will time out, you hear it and simply activate the trafficator again.

Actually I find the 20 second sequence that the trafficator flashes much too long (it irritates other drivers) after you take a corner and I actually put the trafficator back to zero, as soon as I am around the bend :o)

I used the location of the main beam warning light to place the green indicator/flashr warning light, because its the best seen spot on the centre panel.
As a main beam warning light, I use a tiny, when not in use hardly visibly, LED that is fitted next to the Shorrocks pressure gauge.

have fun

Have you ever seen my (above mentioned) reply with photo, of October 10th, at 22.29.47, regarding indicator stem and wiring of dash light?

Kind regards
Anton

Yes I read your post and saw the accompanying photo.

I have removed the indicator stem and have got the trafficator and indicators working. (still to wire in the horn) I have added a LED warning light to my YT's water Temp gauge surround which I had mounted in the same place as yours.

I am using LEDs in the indicator lights and have a 3 pin LED flasher can/relay. Although everything worked OK with the indicator stem, now the indicators flash too fast and the warning light does not come on, but the fitted buzzer sounds.
When I connect my test lamp in parallel with the buzzer/warning light circuit, the indicator flashing speed reduced to normal, but the test light, nor the warning lamp glowed.
I am going to fit a 10w 18ohm resistor into the circuit to slow down the flasher speed and not worry about the warning light.

cheers
Stuart
Stuart Duncan

Inserted the 10W resistor between the warning light and buzzer and the earth and now the indicator lights, warning light and buzzer all work as suppose to. Not fast.

Only problem now is that horn is on all the time. I expect shorting at the slip ring.

Anton,

One day if I come back to Switzerland I'd love to take a look at your car, the snippets of photos I've seen online on this BBS etc, it looks a fantastic top drawer job. Any chance of some photos to drool over, and inspire me for sorting few bits on my own YT please. Not been out in the cars since beginning of September due to other committments and priorities namely getting my garage straight again, which is still works in progress, but slowly getting there.

All best

My Dear Richard,
In all my years of messing around with MG's - mine and other peoples, raising children, sharing lives with significant others and working for a living - you will never be able to do one task to completion (like sorting a garage) before something else comes along. That's just life - it sends you challenges and you work through what needs to be done today.

You can certainly set aside parts of your day/week to spend time in the shed, but after a few hours I find myself working on something that was not on the agenda of today's "shed time".

Now I am retired, I try and do a bit of everything each day - partner time, garden time, keyboard time, shed time and sometimes I even take the dogs for a walk. I have so many projects in the pipeline (shed & office) that I can never be bored or lost for something to do. Eventually some projects are "finished" (well sort of).

Don't be hard on yourself for lack of "shed time" - sometimes life just gets in the way - "Enjoy the Journey" I say........

Cheers

Sorry I'm a bit late on this post but I understand early American cars used the stop lights and front side lights as turn indicators and so relays were fitted to switch over. Perhaps foreign imports were converted this way. Bryan

The bigger MG spares suppliers sell these relays. They where initially fitted to late TDs / TFs (?) as well as MGA 1500 and Z Series. At 90.- they are not cheap....
I had fitted such a relay to both my TDs (which I passed on to my two kids). The YT does not need such a unit, because I have fitted separate Lucas amber cloured flashing indicators at the front and rear bumpers.

Tony,

How right your are, wise words as always. There is always new tasks crop up every day.

Hi all

I found the horn "piggy wire" was shorting out where it passed through the alloy housing to the trafficator assembly. The 2 small bushes were missing and in my fiddling with the assembly I moved the wire and caused it to short out.

As these bushes (you need 2) are no longer available, I am looking at getting some made using a 3D printer.

In the mean time I have fabricated a bush and have all trafficator function and horn working properly.

cheers
