All will become clear.

Thanks.

If you can't be bothered to explain your problem, do you think anyone will be bothered to offer assistance?

However, I am nice...

Missing pin: Normal, a quick check in the Haynes wiring diagram would tell you that.
Speedo not working: Is the cable in properly? Has it fallen out (did you put the retaining clip on it)? Does it work if you put your old dials back in?
Rev counter: Will not work, you need to run a cable to the coil negative. This has been covered multiple times on the forum, have a search. If you're lucky, you may have one there taped up behind the dash (green), if not, run one to the coil yourself.
Fuel gauge on full: Shorted a wire? Dodgy sender in the tank? Dodgy gauge? Again, refit old dials and see if it works normally.

As for fitting, Mk2 dials are a piece of wee to fit, the hardest bit is getting the plug and speedo out the back (hint: tip the dials so they're facing the drivers side window, you should be able to shimmy them around enough to carefully reach in behind and disconnect the plug and speedo).

[NovaLad]

I know how easy clocks are to fit as i've donei t before but these just wouldn't go in at all.

Waht type of wire do i need to use for the green wire?

Where is the negative of the coil and WTF is the coil LOL!

Where abouts do i connect the wire to at the back of the clocks do i wire it to.

I'm off out in a min to a uni interview.

Don't have time to search.

[Jack]

Search when you come back then :p

For the wire type, look in the Haynes wiring diagram, it will tell you the thickness wire used as standard.

The coil is the electrical jobbie that provides current to your distributor (which in turn "distributes" the current to each spark plug in turn, via a HT lead). It is located on the near side inner wing (i.e. passenger side as you look into the engine bay from the front) just below the expansion tank, and is the round thing that people put red bull cans etc over. From the negative connection on that, run a wire to the rev counter on the dials - as to where it connects, pass as I've never done it myself. Again though, a quick glance in Haynes should tell you where it connects.

If they don't fit, I would hazard a guess that the speedo cable isn't in right and is getting in the way of the dials?

[NovaLad]

Right am back.

Ok i have been to a garage and they don't even know what type of wire i need to use.

Does anybody know on here what type it is?

I searched the articles and couldn't find anything.

All i want to know is..

What type of wire?
Where on the back of the clocks do i wire it from?

Where on the coil will it wire to?

Pic of back of the clocks.

[Jack]

What garage did you go to?! lol

Just been nosing in the Haynes manual, don't say I never do anything for you :p

Wire thickness is 0.75mm^2. Splice it onto the green wire that comes out your coil. Note the green wire on the coil is 4x as thick (1.5mm^2) as the wire that needs to go to your dials.

You need to connect to pin 7 on the plug that goes into the dials, that [edit]IS the empty slot.

[NovaLad]

Aye pin 7 is the empty 1.

With it being 4x's as thick can it be crimped?

Can it be any type of 0.75mm green wire?

Thanks for the help you're a star!

P.S a pikie garage.

[craig green]

Just use some fecking wire! Jeez.

Its not powering the starter motor or anything important.

[Jack]

With it being 4x's as thick can it be crimped?
Yes. You could probably use one of those splice connectors, but I'm never too keen on those personally. Bear in mind, we're talking area here, so 4x as thick isn't that much bigger really.


Can it be any type of 0.75mm green wire?
lol wire is wire, I doubt they were even that bothered about what wire type they used when they designed the car :D Anything will do, whatever you can get your hands on. Make sure you use green wire though, as it won't work with any other colour.

[NovaLad]

Ok got some here at my house.

Will the rev counter not working maybe have anything to do with the fuel going up to full?

[Jack]

Shouldn't do. As said, stick the old clocks in for a minute and see if the fuel sorts itself out (before you start faffing about with the rev counter). That'll tell you if the gauge on the new dials is ok.

[NovaLad]

I put the old clocks back in after the new ones failed on me and they are working fine.

[CoupeUK]

You clear on revcounter yet?

[Riggy]

if you need a hand tom come and see me tomorrow or sat and we will do it

[NovaLad]

I think i can sort this rev counter thing out.

I'll go and do it in a min.

Just this fuel guage i'm not 100% about.

Will see what happens once it's plugged back up.

[NovaLad]

Reet i have wired it up inside the plug fine pulled it through the bulk head and around to the coil.

Their isn't or i can't see any green wire to put it to :S

[AlexW]

I had the same type of coil and i had to just put a spade connector on one of the lower connectors, There should be one not used.

Btw i had these clocks and had all the above problems you are having.

[NovaLad]

Please can you get a pic of how you did it?

Would help me alot.

[Welsh Dan]

The green wire goes to the bottom, frontmost terminal on my 1.2 carb, looks like the same coil.

Red...Black
Black...Green

is the arrangement.

[Clean 2.0 nova]

Ok i have been to a garage and they don't even know what type of wire i need to use.

Does anybody know on here what type it is?

Two specifications to look for with the wire mate:
1. A conductive inner.
2. A non-condutive coating.

Job done :thumb:

[Adam]

Can use any wire, its only negative pulse anyway, not going to melt or anything.

Its the bottom right terminal on the coil.

As for the fuel gauge, ive had that problem on sri clocks. Gauge just goes straight off the scale. Think it was just a faulty fuel guage because when i fitted gsi clocks the fuel gauge was fine, so theres nothing wrong with the sender itself.

[NovaLad]

Sorted it.

Went out with the fuel guage still full then after 5 mins it went to where it was on my old clocks. then when i got home it i turned off the engine turned it back on and it went ofull again then after messing aroudn with the wipers and lights etc.. it worked again lol.

[craig green]

Halleluyah!

[Adam]

So you messed about with the lights to get the fuel gauge working?
Nice fix lol

[NovaLad]

Lol... i'll figure out tomorrow what the crraaiick is with it.

The weather is too bad down here today/tonight.

Can't even go pick my exhaust system up off Eastham because it's that bad and he lives 30 mins away with that.

[Adam]

Pi**ing down here too

[craig green]

Just started raining here 1/2 hr ago. Just in time for Gastonbury (16 miles away)

[NovaLad]

The fuel guage still aint sorting it's self out.

It's definitly a problem withing the clocks electrics.

Anyone on here had this problem and been able to fix it.

The fuel works fine with old clocks in so it's the clocks.

[NovaLad]

FFS

The fu*king pin inside the speado cable that goes to the back of the clocks has snapped out.

How much is something like this to get sorted?

And i have checked the diodes on the back of the clocks and it seems 1 is fooked! so i'm going to have to change it.

That's what is causing the petrol rise on the dials i think.

Fail lol

Do you have the clip on the back of the dials that holds the speedo cable on? Also try re-routing the cable a bit, maybe push a bit more thru from the engine bay. Can't remember which side the speedo is on, is it on the right or left of the dialset?

[L14MNP]

LMAO, get a clue son. I take it your uncle was busy during the epic dial fittinglol

How does that help a broken speedo.

Will need new 1

[Clean 2.0 nova]

As for the fuel gauge problem make sure the resistor is in place on the clocks, on the cluster I looked at the 80ohm resistor is placed directly behind the fuel gauge/dial. A bit of discussion from another thread may help -

http://www.pngclub.com/forum/showthread.php?t=100343

Basically if the resistor became disconnected the fuel gauge would read full whack as the voltage across the gauge gets too high (the dial has a very high impedance).

[NovaLad]

This is the diode that we found faulty.

It was then going to be the case of coming home changing it and fitting the clocks back in.

But with me having my typical luck the speedo pin snapped off :(

[Adam]

How do you know its faulty

[Jack]

Ah, misread your post. The pin could have broken due to being stretched.

Ebay ftw, or a scrappy - cable shouldn't cost more than a fiver tbh, but its a fag to get in and out of the gearbox.

[NovaLad]

I think changing the speedo i will definitly get a garage to do.
I know the doide is faulty because i checked it on a voltmeter.

[Welsh Dan]

I had a ballache with motor factor speedo cables, until I got it down to an art.

Go to a scrappy, find a corsa B where someone has allready nicked the dials, disconnect the speedo cable from the gearbox then pull it out from the gearbox end.

Tape some string/wire to the dials end of your speedo cable, then pull it out from the gearbox end, then tape the dials end of the corsa cable to the string and use the string to pull it through.

Fit the dials, making use of the extra slack because the speedo cable isnt connected to the gearbox yet.

Connect the gearbox end.

Fit the grommet to the bulkhead (which will still be on the cable).

The cable should cost you about £3, and it'll take you half an hour to do, tops.

[NovaLad]

Changed the speedo cable..

Changed that diode that was readin wrong on a voltmetre.

Started up the car and the fuel guage went to the top again but straight away went back down to where it should be.

So i turned the engine off well i sorted something out came back started the car again and this happened!
IT'S STARTING TO PISS ME OFF NOW!

http://i75.photobucket.com/albums/i319/MD_Crew/DSC02171.jpg

I'm going to go for a spin and see what happens brb.

[Adam]

As said, my sri clocks do EXACTLY the same thing.
And i know my wiring/sender is fine.

I know other people have had the same problem too.

But my gsi ones read fine.



That idles a bit low too :eek: lol

[NovaLad]

Does It Read Fine When Engine Is Cold For You?

When i was out then it read fine for 20 mins then went all messed up again.

[NovaLad]

Would i be best off just getting some GSi clocks like i was after in the 1st place or MK2?
Would everything apart from the oil be fine then?

[Adam]

I never permanently had the sri clocks fitted, just tested them, saw the fuel gauge was fooked, removed them and bought some gsi clocks.

If yours randomly changes, check theres no wiring loose and bumps/vibrations are disturbing it
