Hi Paul

I think your device might do the job a lot better, so I'll probably get one myself but where the heck can you get one of those for £2-50!

OB,

I got mine many years ago at one of the usual car shows and bought both a large and small one. However, a quick google search and that price I mentioned isn't that far off..

BOA Baby Boa Constrictor Strap Wrench Capacity 100mm

Cheers

Wheel Drama
As The GF Fixed My Car!

As some of you know, I've had a major problem with the Speedo in my XJS

Maybe not so surprising when you consider this Car has been standing for over 17 years!

But the Speedo Needle would suddenly drop to Zero without any warning

As I live in an area with multiple speed limits you really need to keep an eye on your speed

And so I needed to fix this as quickly as I could which would involve

Removing the Speedo Binnacle

Or at least I would have done, if only I was able to take the Binnacle out

But the Steering Wheel was right in the way and wouldn't drop down as it is supposed to

When you release the locking pin by moving a lever

I even put up a Video in the hope that someone could help

But in the end I thought it might have been a broken cable

Though before I took it to pieces I managed to pull out the Binnacle

Enough to jiggle the plugs

Where low and behold I thought I had managed to fix it

As the Speedo then worked perfectly for two Trips out in the Car

Except that on the third Trip the Speedo dropped for a Second but then quickly recovered

My quick fix didn't do it and knew it was just a matter of time before it happened again

Meaning one way or another I had to get that Steering Wheel to drop down

So that I could take the Binnacle out and try and do the job properly

Where the first thing to do was to take off the Indicator Cover and have a closer look

In typical Jaguar fashion, the lock that holds the Steering Wheel up was over engineered

And looked like the kind of a lock you might find on a Safe

With lots of Springs and Lynch Pins to prevent it accidentally dropping down

It looked so complicated that I didn't know where to start

So all I could do was poke various bits with the end of a Screwdriver

But after an hour of doing this where I was getting absolutely nowhere

There was only one thing left to do and that was stop for a nice 'cup of tea'

During which time the GF lent a sympathetic ear as I tried to explain what I was doing

Then She sat in the drivers seat where the next thing that I heard her say was:

'I can't see the problem, it seems ok to me'

'No! You don't get it'

There's nothing wrong with the Steering Wheel

It's just that it won't drop down out of the way

'But it does drop down I can even move it up and down'

No you can't

'Yes I can, Yes I can, have a look!'

OMG! You can! how did you do that!

'I just pulled the lever back and the Wheel dropped down'

You did what! you pulled the lever back and the Steering Wheel dropped down

'Yeah'

On hearing that I felt myself dying inside

'Why how were you doing it then?'

I was pushing the lever forward

'Why didn't you try pulling instead of pushing?'

I don't know!

I know it sounds inconceivable but I never tried pulling the lever instead of pushing it

Which as you may imagine has now landed me with an even bigger sort of problem!

The GF aka ('it')

'It' has now gone into 'Smug Mode' and won't Stop Smirking!

So now I can drop the Steering Wheel down

I got on with fixing The Speedo

to be continued.................

OB, just a quick stupid question, don't you have the car manual which was sold with the car? I'm not talking about a workshop manual but the standard normal 'how to use' manual?

Not a Jaguar over-engineered thing at all OB: Standard Ford column as fitted to all Mondeos etc etc! Never occurred to me you were pushing not pulling. Love it. What a girl, she will never let you forget it, either!

Hi Daim

I've just found the manual for my 1990 and on Page 32 it tells you:

To adjust the Wheel you need to PULL the Lever! Doh!

The thing I think that threw me, was the Lever had so much slack, that I thought the mechanism might be broken.

When I did pull it back, the Lever seemed to hit the buffers and come to a Stop.

With the benefit of hindsight, I didn't pull the lever hard enough.

The Word you might be looking for is 'Dunkopf'

Hi Greg

I never knew that!

Just wondering if the Mondeo version is cheaper?

I've just found the Handbook, which I couldn't find at the time and on Page 32 it tells you to PULL THE LEVER! Doh!

And you're right! The GF won't let me forget this for a long time.

So fully deserving of a Certificate of Mechanical Incompetence.

But looking on the Bright side if there is one, I managed to fix the Speedo (properly this time!)

The Contacts were covered in Varnish (don't know the Technical Term) and one of them was starting to go green.

Full details and Photos to follow on my 'Cherry Blossom' restoration thread.

Fixing The Speedometer

'With a little help from the GF!'

Quick Recap

Having got 'Cherry Blossom' back on the Road there were a few times when the Speedo

Needle would suddenly drop without warning

Which wasn't ideal as the place where I live has multiple Speed limits and so you

really have to keep an eye on that

Although I don't consider myself an expert on these things it looked as though the problem

was to do with the plugs that are on the back of the Speedo Binnacle

Where in order to get to those the Binnacle had to come out

But since I couldn't get the Wheel to tilt in the downward position

(which was later done by the GF)

I could only tilt the Binnacle forward just about enough to 'jiggle' the plugs

Which left me thinking I'd fixed it as for a couple of Trips the Speedo worked perfect

Although when we had a third day out the Speedo needle dropped again

But then recovered a few seconds later at which point I decided that one way or another

That Binnacle had to come out

At which point the GF came to the rescue

And did the very opposite of what I had been doing

by pulling the Steering Wheel adjuster back while I had been trying to unlock the Wheel

By pushing the lever forward where the slack in the lever

led me to believe something was broken



When the GF pulled the Lock Lever back I could finally Tilt the Wheel!




Steering Wheel in the down position, which meant I could finally take the Binnacle out.


Taking out the Speedo Binnacle only takes 10 minutes
But you have to be so careful that you do not damage the printed circuit on the back



Only 5 Screws hold it in but these two are hidden behind two plastic covers which can be popped out easily with the end of a table knife




3 Other Screws hold the side trim in place which can be a bit of a fiddle to get out, so be very careful you don't break it.




Another View of the Side Trim from the other side




This is where you have to be so Careful, if you damage that Printed Circuit

'Its 'Game Over!'

Though in order to pull the Binnacle out, you also have to remove Two Multi Plugs

Which are also plugged in to the Printed Circuit

Where there is just about enough room to be able to get your hands in

without too much of a problem



Now you can see where those Multi Plugs go and why you have to be so careful when you do this job




Now you can see the Multi Plugs which 'may' show signs of corrosion




The Second Tang from the bottom was more corroded than it looks in the Photo as does the Second from top.


All the Tangs of both Multi Plugs were covered in what looked like a Brown Varnish



The Tangs of the Multi Plugs looked like they were covered in Brown Varnish!




After 2 hours of careful cleaning with the blade of a small screwdriver and electric contact cleaner they came up nice and bright


The one thing that I didn't do was clean the Multi Plug Sockets of the Printed Circuit

Except for a dab of Contact Cleaner on a lint free rag

Because I've read the 'Horror Stories' of those who have done that

And then found that their Speedo doesn't work at all

On my Car the Printed Circuit looked clean so I really didn't see any need to touch it

I figured I could do that later if I really had to



When you put the Binnacle back its easy to drop the Top Screws so without a Magnetic Screwdriver I made up a Screw Holder from a piece of Plastic Tube




Screwing the Speedo Binnacle back in place




Without a Magnetic Screwdriver I made this Screw Holder up which worked really well


Now it was time for the 'Acid Test!' would the Speedo Work?



Success! The Tacho is working but in order to Test the Speedo I needed to have a Test Drive


On the Test Drive the Tacho and Speedo both worked Perfect

And with no sign whatsoever of the Speedo Needle dropping

I'd venture to say that I've finally fixed it at last


All Back together again with everything working!

With a little help from the GF!

Yay!!! I'm aware of the female issue. dumkopf, eisenkopf, steinkopf,
heard 'em all. I earned mine by not adding gas when I should. Ran out and had to push more than once. It took decades to overcome. Not done that one for a spell.


Treat her to a nice dinner out. She just might give you a pass.

Hi Carl

I'm not surprised She solved the problem by pulling the lever back, as some Women always seem to do the opposite of what you are expecting.

So a nice meal out does seem to be the least that I can do.

Then the Aerial should stay down, when you switch it on, if that's any help?
I couldn't face trying to get the stereo back into the slot--with all the wiring back there, it's a fiddle. So I simply removed the right fuse from the aerial fuse box in the back. That way, if I decide I do want to listen to the radio, for whatever reason, I can simply slot it back in. I'd prefer to remove the entire thing and fill up the hole, mind....

Well done on the speedo thing. Did you try adding an extra earth as people like Grant often urge?
I like your non-magnetic screw holder--very clever.

Hi Someday

I wouldn't be too hasty in taking that Aerial Out, if its made by Hirshman they are around £75 and I had to pay £11 for the Rubber Grommet that seals it into the Wing!

As for me I quite like the Aerial, as it gives the Car a bit more understated 'Bling'

Be very careful when refitting the stereo in a pre 1993, the centre vent and recirculation vacuum solenoids are very close to back of the stereo, if the insulation is damaged on the connectors these can short on the back of the stereo and blow the AC ECM as happened to me.

Glad you got if fixed OB.

Just for future or anyone else reading this, a good way to clean up these type of connectors is with a soft pencil eraser, NOT the rough sandpaper type. I have used this method for cleaning contacts for 30 years and it works extremely well.

Another reason not to fiddle with the insides any more than I have to....
JapThug has an interesting how-to guide about making a manual recirculation switch which I am interested in trying out one of these days. It's not great to sit in traffic with the a/c on and have exhaust fumes from the car in front blown into your face....

Hi OB,

Good to hear that your minor clean-up of the cluster seems to have cured the problem.

Don't feel too bad about getting caught out by the GF. When I was in my 20s, I spent a whole weekend swapping out a broken gearbox in my then-girlfriend's Morris Ital 1.7 and replacing it with one that I then took out of a scrap Morris Marina 1.8TC. 48 hours of frantic work culminated at 9pm on the Sunday evening. I proudly stood back after finally refitting the gearlever, carpet and centre console. I then looked down and saw about 5 or 6 small nuts and bolts that were still in the plastic storage tray where I'd been putting all the bits as I'd removed them. (Isn't that always the way?!) I comforted myself that they definitely weren't out of the bellhousing, gearbox mount or gearlever mechanism, so were probably something to do with the centre console or other trim, and the car could safely live without them.

I then called to my girlfriend to come and see the fruits of my labour. She came out, looked at the car which, in fairness, looked exactly the same as when she'd parked it 48 hours earlier, then said with rather muted enthusiasm "Oh, thank you darling, it looks..er..great." She then looked down at the storage tray and the remaining nuts and bolts , thought for a moment and said "Is that what caused the problem - they'd put too many of those metal things in it originally?" I could still her laughing quietly to herself as she walked back into the house...But she still married me. Although we separated in 2006, presumably because the arrival of Canbus systems in Jaguars meant I was now beyond the level of my usefulness in fixing her car....

So don't worry. Your GF will soon need a plug fitting on her hair-straighteners or similar and you'll be the main man again!

Paul

Hi Paul

On the Test Drive the Speedo worked perfect and the Miles on the real time LED were in Sync with the Milometer and the Cruise is also working.

If only I'd found the Handbook, it very clearly tells you to pull the release catch back but without that the amount of slack in the lever had me thinking

that something had broken inside.

I don't begrudge the GF a Victory like, as its only a matter of time before She Screws up (again!) and I have to go to the rescue.

Hi Someday

Without wishing to tempt providence, I really think I've got it fixed this time, where the problem seemed to be some sort of a

Coating (like brown varnish) on the Multi Plugs.

As for the Printed Circuit, that part looked in 'as new condition' where as such I was very reluctant to touch it.

Because it's so easily damaged and I have read a few stories of people doing exactly that and ending up with a Speedo that doesn't work at all.

As it's so easy to take out if it goes on the 'Blink' again, then I would certainly think about fitting an extra earth wire.

But since it's working as it should, then I think that it's best left alone.

As for the Screwdriver Gadget, putting those Top Screws in would have been a much more difficult job to do without it.
