Default Relay annoying

Last August ,I decided to say goodbye to my W124 200TE and change to an older model ,much older and not a Mercedes.
I became the proud owner of 1977 244 in Silver (it has the Jubelium badges and the Silver plaque on the glove box but I'm entirely convinced ) very clean and a few spots of surface rust.
I digress.
The horror of the brakes is mentioned elsewhere.
The wiring is another problem. I can not understand anyone cutting out wiring and replacing it with a different colour, rendering any clue you might gain from a wiring diagram useless.
And so it begins ,I find it difficult to find photographs or drawings of the engine compartment , so I might ask several questions such as ;
What is this ?
Where should this wire go ?
& Where would I find this ?

Firstly could anyone tell me what this relay is for/called ? Behind Battery
and what should be wired to it ? I have a Haynes(autobook to follow) so it may be possible to trace the wiring from it.

The best manual for the 240 is published by Bentley.

Can't help you with the relay ID, but it looks distinctly aftermarket to me. What stops working if you remove the wires to it or the ground wires?

Thanks DW42 ,unfortunately the Bentley manual does not cover my model (1977)
Also since the wiring has been butchered it's hard to determine what should be connected to this relay (it is aftermarket manufactured by RS) there are several wires attached which have no destination .

Can anyone identify the following, please....

Number 1 an unknown relay is it ignition related ?
Number 2 Flasher relay ?
Number 3 Black wire with female spade connector ,coming from Number 2 , not connected to anything.
Number 4 a junction box /relay is it light related ?
Number 5 a fused Blue wire coming from the junction box not connected to anything.
The wire in second picture is also a mystery.
I am prepared to replace whatever I have to. Trying to get it back to where it should be, so any help would be appreciated

I have changed the Tyres New Uniroyals
New rear calipers and solid lines.New Ate master cylinder. Front wheel bearings.
New Bosch Headlights & New Cibe Tailights .
Bosch coil, distributor cap and rotor and points.

Hi Bob

#1 is not a relay...surely? On later 240s #1 looks a little different (it's more rectangular) and is simply a junction box/distribution point - if you take the cover off, you should find a chunky incoming cable (I can see that in your photo) and a range of thinner cables going out to feed various things. On the later version, the cover slides upwards and you need to flex the cover to get past a plastic nib which preventsinadvertent opening

#2 is a headlight relay (and this can get a little confusing). I think that it's the relay that puts the headlights on low when the ignition is on, sometimes known as the step relay

Relay #4 is almost certainly aftermarket. Try disconnecting it as DW42 suggested and see what stops, that'll tell you what it's doing. Do the two unconnected wires relate to relay #4?

Good luck. 240s aren't known for brilliant electrics!

Nick

It is possible or likely the aftermarket "relay" received power by the inline fuse holder and blue wire, which is disconnected.

Why not trace so far as you can the wires still connected to that aftermarket "relay" so far as you can. There might and surely likely be a wire that switched the relay so it carried power. A wire coming from a switch perhaps. Or it might have a wire that triggered from the ignition. Be sure all is safe before fully disconnecting.

Can you read any markings on that aftermarket "relay"? You might be able to get it or its purpose and hopefully its terminals' purposes identified by the makers. That could help you to remove it safely.

Thanks Nick, once I had the correct names it was easier to trace from the Haynes.
The block (with numbered terminals) with the RS relay is still a mystery. when removed the pins of the relay resemble the cylinder type relay under the dash.
I'll post a picture tomorrow.RS 348-756 12V 110 Ohms 8 pins in circle.

I'm assuming that the car basically works? It hasn't been vandalised with half its electrics ripped out?

In which case, I'd make two lists:
1) things that work
2) things that you'd expect to work that don't.

You can eliminate some of your mystery components by seeing what stops working if you disconnect them in turn.

If anything doesn't work see whether any of your remaining components might be the problem.

If you can't match them up then run new wiring to the things that don't work.
Then remove any remaining components that have no function.

Easy

[QUOTE=Clifford Pope;2404482]I'm assuming that the car basically works? It hasn't been vandalised with half its electrics ripped out?



Unfortunately Clifford it has ,the first evidence was under the dash loads of blue wire same as the blue wire in the engine bay. The tail lights had a thick red wire wrapped around the earth sprue (I'll call it a sprue because it resembles one from a plastic kit) and screwed it to the body at the earth terminal.
I used a multi meter to determine what was +12v constant ,+12v switched and ground/earth. But even armed with that knowledge it is hard to undo the butchery .
A little knowledge ......
And so I will need all the help I can get .

Tail light earth .... somehow that always gives a bit of bovver.

One year on a 740 (Similar rear light assembly) the rear lamp failed the MOT. It was the earth connection within the lamp fitting. The garage fixed it free. After I had said, you should have fixed it right last year!!!
