What's the difference between the two rover dash's. ? Apart from the colour.
Nothing... it is only the front panel cover pin-stripe colours that are different.
I think the part numbers are all the same.

There is a different dash used for the later MG Montego 2.0 EFi... it is a lot more complicated and has an integral warning messages display.

Getting a bit bored of working on the VW looms.
My own fault, I know....

Did a few more updates on the main white 29 pin D connector.
Added a 3 wire loom for individual indicator tell tale wires and the hand-brake wire.
---------------------------------
Also made up a dimmer switch bypass jumper between pins 8 and 9 of the G connector.
Dimmer is not needed if I use the MG / VP dash.
That is wired directly to earth via a 10 k ohm variable resistor.
This allows me to link the dash illumination wires to the "standard" illumination pin in the VW connector.
----------------------------
On later vans there are two oil pressure switches.
0.3 bar for the oil light and 1.6 bar for the dynamic oil pressure sensor circuit. The DOPS or buzzer of doom is notoriously unreliable, so I will not be using it.

I am going to use the 1.6 bar oil pressure wire for my speed transducer signal wire. This means that I can use a 'redundant' wire that is already in situ between the fuse box and engine bay.
I have therefore wired my MG / VP speed signal wire to the VW terminal for the 1.6 bar wire.

This leaves me just two wires to sort.
1 - Brake fluid level sensor - need a switch for this too.
Currently out of stock in the UK.
2 - Cruise control tell tale. As you may be aware, I have a Saab cruise control unit that I plan to fit.
It is the same as the GM / Vauxhall / Opel unit, so easy enough to do.
I have heard that the VW units work on vacuum pressure.
The main problem being that they are often faulty due to system vacuum leaks or simply have insufficient vacuum to maintain road speed.

The oil pressure thing sounds familiar. I had an old (original style) audi coupe, it has the dual oil pressure switch, the second one was used above 1,500 rpm for when the car was driving.

The problem with 1.6bar is that it may come on at idle.

Yep same thing for the T25.
It triggers a buzzer if the pressure drops below 1.8 bar with the revs above 2000 rpm.

I have drawn up a reluctor ring with 8 teeth.

Plan is to use the 6 CV boot cap-head bolts to hold it on to the inner CV joint flange.
I think the joint outer diameter is approx 100mm
Fingers will extend 20mm beyond the joint flange.

Overall diameter = 140mm
Finger width would be 27mm at the tips.
And 27mm gap between each tip.
Calculations as follows:-
(140 mm dia x pi = 439mm circumferance)
8 fingers and 8 gaps. - so
439 ÷ 16 = 27 mm.

I will need to find out the pitch circle diameter of the joint bolts.
I suppose a cheat would be to get a set of joint boots, and use those for a drilling template.
I read somewhere that it could be 86mm

Something like this....

Image

The diagonal dotted line is to split the reluctor in half.
This way, it will be easy to fit the two halves, without having to remove the joint off the end of the shaft.

I am sure Troy will love my Visio drawing.

Does it need the folded section? can you not just use a flat profile, would be cheaper.

Or find some way of tapping an ABS ring on the drive shaft.

I will be making it myself, so not too expensive anyway.

The folded section will wrap over the CV joint, so it will allow me to mount the pulse pick-up closer to the gearbox, and away from anything that could be thrown up from the road.

I was thinking of making the folded part double-skinned to ensure that the pick-up will see the metal fins effectively.

I also noticed a very nice metal strip in just the right location for mounting the ABS pulse pick-up / sensor.
It is used to mount the hydarulic clutch slave cylinder.
It should almost look professional / factory fit when done.

Last night was a change of scene...
I spent a fair chunk of time on my back under the van removing the left drive shaft.

It is the usual VW type six bolt bolt-on joints.
I cannot think of anything worse than cleaning up the forty year-old grease from the joints.
It goes everywhere and uses up loads of cloths.

Just to be awkward it uses double hex spline like socket screws. The outer joint is buried deep within the rear wishbone / hub.

The things I do to research the speed sensor reluctor.

Oh blimey - this is Cavalier deja-vu.

Every time you do a job on an old vehicle, you end up finding more problems...
Finally cleaned the CV joints on the left drive shaft of the camper van, only to find big shiny furrows where the ball-bearings have worn a groove.

Image

Darn it - more expense - new cv joints required.

To close the chapter on the MG / VP digital dash -

After a long discussion with the missus and after doing a bit of financial reshuffling...
She finally reported that she was more than happy enough with the 'boggo standard' analogue instruments.

So I finally put the digital cluster back up for sale on fleabay.

But that will not be the end of the speedo pulse sender milarkey. There is still the Saab cruise control and Corsa-C epas afteralll. ;)

It did look nice on the kitchen work top going through the motions looking like "Blackpool illuminations".
But that is life.

I really should just do what is needed and stop faffing with expensive and un-necessary distractions. - lol

Indeed - it has now sold for full asking price.
Sounds like it is going to a good home in Preston. :)


Update :-
25th Aug 2021 8:00pm - cluster moved to it's new home in Preston.
Taken by motoring enthusiasts Rob and Michelle.
Looks like it will be well cared for.

As a side note, Rob and I compared angle grinder accident stories. Being a hands on car enthusiast can be very dangerous. Although I could not match his recent 16 hours in A&E. Mine was just 1 hr with the sewing machine to fix my "van trousers".

It is a long time since I faffed much with electrics.

The wife wanted me to get a clock from her first car.
Nothing normal for her - she had a 1981 Alfasud 1500 Ti Green Cloverleaf at the age of 17. :shock:

Most 17 year olds had a clapped out escort or mini...
Not my missus.

So I have kept a half-arsed eye open for one for a few years...
Until one popped up recently.
Talk about retro... it has a similar style to those red led digital watches from my teenage years. :hair

Image

It came untested, but after a brief clean and a check over it works fine.
Strangely my re-purposed pc power supply went with a huge bang a afterwards.
Oh the joys. :roll:

I had one of those watches, I saved up my earnings from a sunday market job at 15 for it. Cost a small fortune at the time.... and was totally useless in sunlight!
It was the same price as a self-assembly basic calculator, as advertised in magazines i.e. practical electronics what's that :scratch courtesy of the late Sir Clive, a true pioneer in bringing affordable electronics to the masses at the time.

Back on topic now, is this for the van or do you have a new project in mind?

Dare I say it .... for the van, maybe.
It is all very period (early 80s), and sort of goes with the red and blue of the VW radio. As used in the VW range in the 90s.

The last few T25 / T3 vans just squeezed into the 90s (1979 to 1992), so I can sort of get away with it :)

A proper Blaupunkt Heidelburg digital radio from very late T25s / T3s is silly money.
Blaupunkt Alpha, Beta and Gamma units from the Golf 4 and Transporter T4 etc are ten-a-penny.

Not sure why I am being so semi-purist about the period, when I am so happy to cross borders of manufacturers in such a blatant way.

With the cold weather making the Cavalier very un-appealing to work on, and the fact I haven't seen the camper van for months.....
I had a chance to do some faffing in the warmth of my kitchen.

Only a quick job... about an hour all in, including the preparation of wire ends, soldering, sleeving and loom binding.

I am one of the few NHS engineers in Manchester for assessing and carrying out technical adaptations to the wheelchairs used by our 11,000+ user population.
But - the adaptations of the electrical fleet are almost solely carried by me or under my direction.
No pressure there then.

This is a controller from a high-end electric wheelchair.
The job in hand was to make the little control buttons detachable from the joystick controller, without having to undo the cabling from the wheelchair.

Image

Therefore simply get a spare extension loom, cut and shut the loom to allow the control button wires to be unplugged from their jack plugs, which are usually secured to the underside of the joystick controller.
The buttons are used for on/off and mode functions.

Well it looks like winter has arrived - lol
Minus 4.5°C this morning on the car gauge.
Just about the lowest that I have ever seen it displayed

Here are pictures from last night (Sunday).

Not sure where the white mist came from, because it was not there when I took the photo...

Image

Equally as bizarre, I didn't think the hill that I live on was that high. But you can clearly see the cloud line below and beyond the houses in front of mine.

No sign of Manchester which is somewhere near the central white glow in the distance.

Image

Very weird to see... or not see

Here is the same view of Manchester on a clear day (4 days later).

I was having a sort out today,
and came across my "Halfords" branded Haynes derived manual.
The book credits Haynes Publishing, 1997.

Image

Image

It is a cross between a Haynes and a Porter manual.
The bonus is that all the images inside are colour photos.

Image

Image

Amazingly, I do not recall ever reading it - lol.
And I have never seen another copy since.

I have one for an early VW Golf somewhere. Don't know why, I have never had a VW car. :scratch
I have worked on a few 80s / 90's Golfs, Polos and Jettas though.

Had another tidy of a draw today, whilst making my toast for breakfast.
I came across this...

Image

A blast from the past - I was only a member for a year and so not as involved in car stuff that much.
Probably from around 2007-ish.
Basic as hell, but I loved the Mk2 Cav.

------------------------------------

Talking of finding things....
I finally found this.

Image

Not sure why it was in the boot of the Cavalier, but that is where I found it after putting stuff in from the Vectra whilst it went for it's MOT.

I know someone was interested in it, but I could not find it in December to get the part number.
I think I know who it was...

This could potentially be a separate chapter -

I amost started a new thread that I was going to call "Rustoration!!", but that would have been naughty as it is the title of someone elses van restoration thread on the Club8090 forum for like minded VW T3 / T25 / Vanagon van money-pit owners.
Where else would you find a van model called a "Club Joker".?

After procrastinating for many years, and leaving complex welding jobs for Troy at his unit -
a discussion about how poor funds are and trying to budget between parts, labour and materials the other evening resulted in Troy advising that I could try doing some welding myself. Potentially saving £25 per hour.

Lord knows, there are probably 200 hours of bodywork to be done.
Cutting, dressing, cleaning, treating, welding, dressing cleaning and treating / coating.

Now it is about fifteen years since I last used my welder in anger.
In that time I have grown lazy, apathetic, unsure of my welding abilities, and becoming expert at making stupid excuses to do nothing.

So I pulled out my welder from our secondary storage shed (formerly known as a professional sized kennel for our first Great Dane, circa 2005 to 2012).

The welder has been protected from direct elements (rain, sun and the like), but still exposed to the semi-permanently damp air of east Manchester.

First job was to kill about half-a-dozen spiders who were demanding squatter's rights in the casing.

The welder casing was / is very rusty with a lot of paint and painted on tables and decals flaking off.

Image

Image

Image

First job - check it worked after such a long hiatus.
Amazingly it crackled into life, telling me that I had a lot of practice and technique revision to do.
(Crap welds).

Next job was to wash off any loose flakes and general skank,
Then dry it, and give it a good polish.
Furniture polish will do for now.

As you can see it is a modestly cheap make.
A Nu-Tool Gas-less welder.

I know everyone says get a proper MIG as they are easier to use, but to be honest it was good enough in 2007 to do a cracking job of welding on a rear nearside arch on my mk2 Cavalier.

On a more down to earth level - It was a Christmas gift from the late father-in-law (so I must have been highly thought of, or liked a lot by him - he did not suffer fools).
And the plan is to use it on the van that is still registered in his name.

I hope that I will be able to post up some decent weld pictures soon - but don't hold your breath.
My official welding training was in 1984 (gas welding, electric arc and brazing) I have not done very much since then. Eeek!!
This was back in the day of Youth Training Schemes at large employers like Ferranti electronics (in my case), where you spent a year learning basic engineering skills, making your own tools and tool boxes.
I still have everything I made in the main shed.

Moving on...

I have a face mask from an Aldi stick-welder that I bought in 2015. Sadly, after 30 years all I could do with that welder was blow holes in the van floor.
So that has been consigned to a junk box in the back of the van.
But yes the mask is simple, but will do what I need it to, until my budget can stretch to an automatic helmet.

Assuming my welding improves enough to warrant pretending that I can weld.

Wishing you well! Practice and lots more practice preferably on plenty of scrap stuff first! Thin material (bodywork!) has got to be the most difficult to perfect, with something chunky there's less risk of blowing holes in it.
It's also a skill that relaxes if you don't keep at it.
I restored my Morris many years ago and used MAPP gas/oxygen and can vividly remember the sound of the sparks sizzling away in my ear when upsidedown welding!
Hope it goes to plan.

Thanks -

I have been looking online, and it appears to be quite easy to convert my welder from gasless to MIG.

General gist is to reverse the polarity of the earth clamp and torch connections.

Plumb in an electronic gas valve.
And connect a gas bottle and regulator.

Not sure if I need to change the tip of the torch too.
But it all looks doable for a modestly manageable outlay.
