MG MG Y Type - Trafficator and direction ynd hazzard together

Hi
in the moment my car gets the new self made harness wiring
the trafficator works again, cleaned and greased
the lamp inside has his own wire so the lamp is blinking with the front and back direction lights.
Found this here and made with the plan my own solution
https://www.dkw-f5.de/werkstatt/licht-blinker-und-winker/winker-blinker-teil-1/
The best i could find

after some hours of thinking my own solution in the picture
all will come in the battery box so i can look easyly if something is wrong

perhaps i will add the 4 way relay later so that i can swith off the trafficators and his light with one switch
will etch a layout at the end of next week and will see if it is working as it should
also i will ad relays for headlight diplight and horn

all swithes on the dashboard has low power so good for security

what do you think of my solution
you use the trafficators or not ?

does anyone know how much power the coil of the trafficator need ?

Have you read this article already on this website? This is how I accomplished this issue.

https://www.mg-cars.org.uk/imgytr/hints&tips.shtml#Fitting_Flashing_Turn_Signals_with_Trafficators

There is a link to a PDF file on our site for a wiring diagram too that I used.

like the old diagram, it is not allowed here in Germany.
you must have a warning light, all lamps flashing, this must also work without the ignition switched on!
there must also be a red warning light on the dashboard
the direction indicator must have a green lamp on the dashboard and must work with the ignition switched on.
the indicator light must also flash, so you must have a separate cable for it
So the old diagram does not work for me
the car is 20cm too long, so I have to have directional lights as well
In my diagram it's easy to make another switch to stop the traffic light working, both the coil and the lamp

I also need a special relay for the LED so that the flashing time is correct
FT Franz

Not 100% perfect because some holes are not exactly in the middle
But i made this for the first time

Design, etching, making small holes, putting the parts on it ....

Hope that it will work as it should

Tomorrow some small work and then it will be ready for install

also i have to controll for the direction of the diode



simply awesome what you can do today with research on the internet
I loaded a program for the circuit board layout, then found a circuit that understood, then changed it to my wishes, then exposed, etched, drilled and now I hope that it works too

now i have to design a little box with freecad, print it with my 3d printer.....





FT Franz

It was quite difficult to apply the solder evenly to the board.
I had to make a bridge at the top left because I had an error in the layout there. I did not tin the switch tracks exctra because no large currents flow here.
you don t see the backside when it is installed in the battery box




FT Franz

here some more pictures
one 3d picture from the assembly i will fix in the battery box
it will be covered with a cover and a mg logo
it will be the oringinal like octagon logo, not like the picture only mg




FT Franz

2 screws and i can take off the assembly to check the wires
relay circuit for light, dip light, horn, radio
trafficator coil left and right and 2 direction light relays

over the assembly i will fix a box with classic tools like pliers, hammer, tyre lever and so on
we will see ;-)




FT Franz

I have found the problem
two things I know now ;-)

but I was really close to throwing everything into the corner

I found the first error quite quickly
the LED flasher relays are wired a little differently,
I looked at a few circuit diagrams and then assigned the pins a little differently,

then the hazard warning lights worked properly,
when i wanted to turn right the relay buzzed but it also blinked when i wanted to turn left there was a steady light.

the coils from the trafficator worked as they should.

here, plugged there, plugged again and again it did not work.
Then I looked at the circuit diagram again and again,
then came a flash of light
I had quite different lamps in my experimental setup, I just took what I found out of the box.
but since at one point the function is dependent on the same consumption on the left and right side
bingo
exchanged the lamps and everything actually works as it should.

and again one cliff less
hope it works when it is installed

Chaos on the desk �
But I have done it

also i have printed the case for it in ABS, fits perfect
install is easy because you stand near by and don t lay on the floor of the car
later i will make a tool tray sitting above the battery box
and the relais get a mg cover printedf too
so you will not see a lot of it

so now i have a optimal legal direction light and hazzard light tool and i can switch off the trafficator
the hazzard light switch and the switch for trafficator coil i can use all switches i can buy
will take mg classic like switches
for control light i will take small led s
