You should be able to lie on the floor, stick your head up under the dash and take photos of the underside and back of the instruments, to see what is going on back there as regards fixings.

Sometimes gauges are held in place by brackets like this, held on by knurled nuts. You undo them, draw them off and then push the gauge out of the dashboard from behind. It may require a bit of a twist and wiggle to get it going. Once it is free and you have drawn it forwards, you can disconnect it from the wiring harness.

ah thats good to know! I had a feeling the stud on the back had something to do with mounting it :) I just hope it matches up with the existing mounting hardware for the smiths gauge!

Triumph Spitfire Instruments and Gauges

and ooh thats interesting! good to know what the voltage stabiliser looks like! going by its size it must be up in the dash somewhere as I have not been able to spot any extra electrical components otherwise throughout the car

just doing a bit of quick googling, they are quite simple devices, http://www.britishv8.org/Articles/Voltage-Regulator.htm (I remember finding out a while back why old British cars had them/why they where needed, but I never actually looked into what they looked like/where comprised of until now!)

should be easy to bypass if needed :)

I checked the butterfly at the carburettor, with the cable disconnected, and it easily opened and closed (with the spring fixed to the air filter, as @Zelandeth pictured) when I moved it with my finger. For the throttle cable, it seems to be free but tight along its length because I disconnected the twist grip and pulled the inner cable and @LightBulbFun saw that the throttle butterfly open and close. The twist grip is free to rotate when off the handle bar. But I did notice it was fixed too far up the handlebar, by the bend which it rubbed against, so I moved it more towards the end, and it is now free to rotate. With it fixed to the handle bar, and the cable hanging loose, the throttle appears to work, but it is stiff, and the return is sluggish. If it is held up, like Zel’s pic, it does not return properly and the throttle remains open. As @Mrs6C says, fix it at close intervals, but I would like to see the path it should take from one end to the other, perhaps pictures of the route on TPA from Zel and TWC from @dollywobbler would help. I think once we find a path without any tight bends that might be the answer.

For the fuel gauge, I have found several Veglia Borlettis and connection diagrams, but none exactly like this. At the sender, one is for a switch to earth for the low fuel light, so the light connected to the + terminal goes there. The other two are the level resistor, but not sure of which is what colour, or how the connections go. Further investigation to come.

Not sure if REV has a voltage stabiliser like that, it would be mounted on the back of the speedo, but I cant see one in Claire s pic.

I think the picture @Mrs6C used i think is just a generic picture to show how dash gauges are mounted normally :) (I mean Im not aware of any Model 70's with a red dashboard!)

from what I can tell REV will have one somewhere as she is a later Model 70 and from March 1976 onwards they gained a stabiliser

Model 70's from Production start, to March 1976 had gauges like so, note the chrome surround and small speedo

then in March 1976 the Model 70 got a bit of an internal face lift, among a host of other changes (like a rollover bar and a headlining) they changed to different gauges with black surrounds and a much larger speedo, so the fuel gauge was also changed (still a smiths just a different type) and this is when the fuel stabiliser was also made a part of things

That's correct. The photo was of a Triumph Spitfire speedometer and the drawing was a set of Spitfire gauges from the Rimmer Bros online catalogue. They were to illustrate how round gauges like these were often fitted.

@Mrs6C,  Ahhh!! I see !! 

If you look at REVs picture, you can see the green throttle cable hanging low, that is the position it almost wants to work. Fix it higher, and the problems come.

@LightBulbFunForgot to mention REVs charge light problem:  There is a large relay somewhere to operate the starter side of the Dynastart. You can hear it click when you operate the starter with the key. It could be the contacts in that. I did notice a voltage regulator in REV positioned on the chassis near the rear offside light.  That is the most likely place for the fault.  There will be a type number on the top. It looks like the Bosch one on the Daf. The Daf has a conventional starter and dynamo, so they are probably different types, but in the same box.  Those are places to look for REVs charging problems. I will have to look at the circuit to see how it works, probably similar to the NSU, which also had a Dynastart.

Just went and grabbed a couple of updated photos to confirm the interior routing of the cable on TPA

IMG_20211123_115412.thumb.jpg.075a10f772fb38802e569d6c5542ba9c.jpg

The cable used to run through the circular cutout in the brake actuator yoke, but that caused the cable to be pulled too taught at times, particularly when reversing into parking spaces.

Did try snapping a couple of photos under the car but you could see everything in them *except* the throttle cable, I'll need to try another time from the other side I guess.

@Zelandeththanks for pics! @LightBulbFun, REVs indicator switch is on the right, so to get the cables straight path as TPA, it will have to be moved over to the left side.  If you remember, the lever got in the way of the cable.  I think REVs cable goes through a hole in the vertical panel(does it?) so it should be moved to where TPA has it. Both of those changes should make a favourable difference by making a looser bend. Next is to look at the path underneath the car.

Guessing the twist grip is a contemporary motorcycle part which would normally be used with a much shorter, less convoluted cable. Would running the cable inside the car simplify fitting, particularly with LBFs restricted working facilities?Another thought, would one of those dash top  solar panels help keep the battery topped up? It seems the electrics are marginal, with little scope for upgrading, so every amp would help. Notice a fellow down the road is using one on his GT86, the modern one, which he parks on the road. Just coming up with a few suggestions, as like everyone else, I want to see a chipshop photo of REV!

If it helps you out Dez, I’m heading up your way on Saturday afternoon and back again in the evening. If you would like the battery taken upstairs I can do that to save your back. 

ooh yes please! that would be very much appreciated! and gives me a few days to rest up :)

I think you already have my details from all the lightbulbs and computer bits you have very kindly sent me overtime! but ill PM you my number so you can contact me quickly if needed and let me know if theres anymore details you need!

 

I have to say I am very thankful to all, especially recently with all the fellow forum members that have come to my aid! it is seriously appreciated!

Oooh! I had been looking for that video again for ages! I found it way back when in the early days on here it was how I discovered the YVX-L block of Invacar Model 70's 

thanks for finding/sharing it again :)

but the video must have been pulled sometime back and only re-uploaded yesterday!

tis also a good video for showing a Villiers (AC Acedes Mk14 Model 67 in this case) machine in action and how reverse on them works :) 

I remember being confused at the control scheme I thought by the way the lady was grabbing the tiller bar with 2 hands it must of had bicycle controls, but I now know that she was just grabbing the tiller bar with both hands!

(pretty much all Ministry Villiers machines where Tiller control regardless of how many operable hands/arms you had, so it was common for people with 2 functioning hands to grab the tiller bar with both hands)

Ooooh Hello there!

now question is, is this a load of Model 70's (or AC Model 67's? you never know! given we can only see the roofs) that need rescuing, or is it just @st185cs's lot that have been papped again like last time LOL

 Many thanks to @CaptainBoom who came today  and very kindly removed REV's battery for me despite the awful weather! as I predicted it was a right faff to get it out so im glad and thankful I did not have to do it alone!

 I have it on charge on the balcony now :) standing voltage under no load was about 12.5V or there about hopefully it will charge up alright!

 

and I took the opportunity to check and correct REV's tyre pressures with a portable tyre pressure inflator and gauge I got recently from amazon this one for those curious https://www.amazon.co.uk/gp/product/B071XTHWQF 

it looks like Adam was able to set all the tyre pressures to how they should be which im pleased about and only 2 of the 3 needed minimal correcting :) 

for those wondering 1 rear was good at 22PSI the other rear was at about 20.5PSI and so topped that back up to 22 and the front was down to 15 so topped that back up to 17 PSI, will be interesting to see how they change overtime!

No problems, I'm glad of the excuse to get out for a bit!

Spent a little time this morning and  managed to trial fit everything of importance to the chassis, thankfully everything lined up and fitted straight up . My friend James has been heavily involved with making the chassis so I'm not surprised it is bang on as for a man of his talents it's really a minor project. Here are a couple of pictures of the chassis and one also of one of James' more involved projects, a full scale 3 ton Ruston Proctor steam  tractor that he built from surviving drawings of an engine that sadly never made it into preservation. In future is is planned that Brian comes with us and the Ruston when we steam off on the road to rallies, not only can he be displayed but also can provide a convenient way to get to the shop for Cider supplies!

wow thats amazing! its awesome to see Brians chassis rolling for the first time :) must have been really satisfying! 

not long to go now! given you got most of the bodywork already sorted! its pretty much just* put it all together again!

      Well I've been meaning to sign up here in forever, but kept forgetting. Thanks to someone over on another forum I frequent poking me about it recently the subject was forced back into my very brief attention span for long enough to get me to act on the instruction.

      I figure that my little varied fleet might bring you lot some amusement...

      So...we've got:

      1993 Lada Riva 1.5E Estate (now fuel injected, as I reckon the later cars should have been from the factory...).
      1989 Saab 900i Automatic.
      1987 Skoda 120LX 21st Anniversary Special Edition.
      1985 Sinclair C5.
      2009 Peugeot 107 Verve.

      Now getting the photos together has taken me far longer than I'd expected...so you're gonna get a couple of photos of each car for now, and I'll come back with some more information tomorrow when I've got a bit more time...

      Firstly...The Lada. Before anyone asks - in response to the single question I get asked about this car: No, it is not for sale. Took me 13 years and my father's inheritance to find the thing.


      Yes, it's got the usual rusty wings...Hoping that will be resolved in the next couple of months.

       






      Next, a proper old Saab. One of the very last 8 valve cars apparently, and all the better for it. I've driven two 16v autos and they were horrible - the auto box works sooooo much better with the torque curve of the 8 valve engine. Just wish it had an overdrive for motorway cruising...









      Next up a *real* Skoda...back when they put the engine where it belongs, right out the back. In the best possible colour of course...eye-searingly bright orange.







      Seat covers have been added since that photo was taken as it suffers from the usual rotting seat cloth problem that affects virtually all Estelles.

      Then we have possibly the world's scruffiest Sinclair C5...



      Realised when looking for this that I really need to get some more photos of the thing...I use it often enough after all! We have a dog who's half husky, so this is a really good way of getting him some exercise.

      Finally - again, I really need to take more photos of - we have the little Pug 107.



      Included for the sake of variety even if it's a bit mainstream! First (and probably to be the only) new car I've bought, and has been a cracking little motor and has asked for very little in return for putting up with nearly three years of Oxford-Milton Keynes commuter traffic, before finally escaping that fate when my housemate moved to a new job. Now it doesn't do many miles and is my default car for "when I've managed to break everything else."

      I'll fill in some more details tomorrow - I warn you though that I do tend to ramble...
