Good day people

I am a new member and I need some advice.

2.5 has been in a crash and stood at the panel beaters for almost two months, since I got it back had no joy with the car.

My problem is a clattering relay - I believe it is the main relay that should close as soon as you turn the ignition, but mine clatters even when the car is off. To stop the clattering I must disconnect the battery.

The car does not want to start at all, my aircon goes on and of as it pleases, sometimes the motor is turning but mostly it stays dead with only the dash lights coming on I.E. battery and oil light.
The hooter is not even working.

I had the battery tested she’s fine - checked for bad earths all is fine

Any ideas as to where I can start looking?

Thanks
:confused: :help: :help: :help: :confused:

It could be a faulty main relay, or the circuit opening relay, both are in the main fusebox under the hood (bonnet)
listen/feel the relays, find out which one it is, and replace it.

With the engine off... (key off)

are the headlights bright when turned on?
is the alternator ok?
what is the dark current amperage? (current drawn from battery when all is off... clock etc)
did you check the circuit opening relay as well?
Which relay exactly was/is chattering?

I have the manuals and wiring diagrams..

John

I am going to bed now its almost midnight and I had no joy -- Keep an eye on this I will post a pic tommorow morning so that I can sh you exactly which relay it is.
Like I said no joy

The Headlights don't even want to come on, unfortunately there is no way for me to test the alternator unless I take it off and test it on my bench tester - I guess I will have to do this but that is tommorow nights worries.

How do I test the dark current amperage?

Which one is the circuit opening relay?

Thanks for your help so far:)

Dark current is measured by removing one battery lead, and wiring the ammeter in series. (i.e one lead on battery, one on loose battery lead)

The dark current should be 20mA maximum.

The circuit opening relay is one own and one to the right of the main relay.. will post a pic later.

Hi

As I said last night here is the pic.

If you have a look at the pic you will see a yellow, green and black relay, the trouble maker is the black one.

Something else I found out is that if I pull the BTN fuse out( this is the first yellow one from the top) the black relay do not Clatter any more but as soon as I turn the IGN on or the Headlights then the thing starts clattering again

Apperently the BTN fuse is the main fuse for the tail, stop, room, door, lock and hazard fuses.

The black one.... ok, seen as there are two.. })

The black one at the bottom, is the A/C relay.

The black one on the right is not listed in my books, and on my car there is a fuse in there instead of a relay.

The Yellow one is the main relay, the green one on the right is the circuit opening relay.

The others on the left are for the A/C cooling fan etc..

Look underneath the fusebox cover, it tells you what is in there... in mine, the right hand black one is crossed out.

Sorry I can't be of no more help.. although if Dave is lurking, he had a South African MX-6 and may have some idea what that black one is for.

Have you got fog lamps John?

'Cos the black one on the right is labeled 'Fog Lamp Relay' on mine.
(And the blank space just above it is R Fog Relay.)

T'other way round Ken...

Top one is front fogs.. middle is N/A bottom is circuit opener (fuel system)

I'am betting Telstar doesn't have front foglights..

OK bottom line and all I could come up with is these two.

The relay is a std 4 pin normaly open relay. For it to be clattering there must be a current passing throught the relay to make it engage. The relay shown is for the fuel pump and injectors so no wonder it wont start.(if it is the right one) Either the voltage getting to the relay isnt enough to hold the switch closed (IE hold the small mechanical spring in place so it breaks away then tries again) or there is an intermirttent voltage. Either way these might help trace the fault.

mine too John has a fuse in the position.

Don't know about yours Dave, but there is a difference in the manuals... volume one lists the main relay in the same position as your pic.. i.e. the black one on the right.
The wiring manual, lists it as the Yellow one in the middle..

On my car, I don't have the black one, just a fuse, and the yellow one is marked in the lid as the main relay..

???

Just these diags were the closest to a match I could find.

Beg to differ John. :)
The 626 obviously differs from the MX6 then. Mine is definitely different.

You sure Dave? You said the green one was when you replied to Andy here: http://www.mx6.com/forums/showthread.php?s=&threadid=70427

Here's the inside of my fuse cover. Fuses are R Fog (Black) - Fog Lamp (Brown) - Circuit (Green) and EGI Main Relay (Yellow).

It's obvious to me, the black relay is for something not fitted to UK cars..

Just seen your post Ken, and yours is certainly different, must due to it being a later car, because Dave says his is same as mine.

As for Telstar, it's anyones guess, but if your reading mate.. remove the relay, and see what doesn't work anymore..

Mine is not the same as Telstar. If you see on the two pics it shows the B3-02 Relay in the same position as telstar is showing and if you find that relay on the wiring diag you see it actually feeds the fuel pump Relay and so the fuel pump, Was just staing that no wonder it wont start because it stops the fuel pump and injectors etc.

BUT IT ISNT THE SAME AS MINE OUR OURS ;)

Thanks for all the input so far.

John
I have looked under the fusebox cover and where the black one is (the one in question here), is blanked out on my cover.

My car has no foglamps in front, thats mainly due to the fact that here in Southen Africa we've got nice sunny weather most of the time.

I have taken the relay out but since the whole car is screwy I can not find anything which is working or not with the relay in or out.

MX6-uk
My relay is a 5pin relay but as far as I can see only four pins are used. If that relay is for the Fuelpump and Injectors I will test tonight to see if there is power on the pump and injectors.

Many thanks for the diagrams.

Now its time to tell you what I discovered last night purely by accident. With a test light connected to the Neg Bat terminal and the other side of the test light touching the body the test light comes on. So there is a major short somewhere in the car. MX6-UK this confirms that there is a current flowing through the relay when it is not suppose to, like you said the voltage getting to the relay might not be enough or its intermittend. I also discovered that nothing in the interior works no lights, no radio, no hazards, nothing except for the charge light and the oil light on the instrument panel when the ingnition is on, allthough with the relay in and the ign is off these two lights don't go off completely.

Once again thanks for your time and effort. I will have to invite each and everyone of you who helped me for a proper South African Barbeque once this car is going again.

:) :) :)
