humm intersting. I thought that technically the KPH reading speedo on the corolla should have been a fail but it lights up and works so maybe not. I would like a MPH one though because I'm always worried how fast I'm going so end up going too slow.
I know there are kits out there, but I'd like to hear a proper recommendation from someone with a universal one...
As I posted earlier, I fitted a "universal" Acewell dash in my Mini. I did this because of the engine conversion. I assumed I would be able to run the VSS from the Vauxhall gearbox, but in the end I fitted the hall sensor that's supplied with the kit, made a simple bracket to mount that inside the back drum and put the magnetic pick up into the 'spare' threaded hole in the studflange. It was actually surprisingly easy, not least because the thread on the magnetic pickup just happened to be the same as the thread in the hub!
To install them is very simple, it's just running wires to power them, wires for the tell-tales and the wiring for the hall-sensor or VSS. Calibrating them is easy too you just input tyre circumference. You can set them to KPH or MPH, the odometer is legal and they are IVA compliant. The Acewells, hmmm, they work OK, but they aren't pretty TBH. Their background is providing speedos for ATVs that were being made to comply with VOSA/Construction and Use etc. regulations to be put on the road. They are a bit "bikey" looks wise, but the main advantage for me with the GRP dash was that they have all of the tell-tale lights, a fuel gauge, a temp gauge, trip timer (handy for the 'ring) trip mileage, RPMs, shift light.....all for about £170. They pop up second hand too.
Again, there are other alternatives that are all road legal, but Acewell are by far the cheaper option. Stack do some lovely kit. If you want a round, older school speedo then Smiths may be a better option.
In terms of the MOT, I aint up on the 2012 regulations as I stopped testing years ago.
If your car doesnt have a speedo (not a working speedo, but no speedo at all), is it an MOT fail? I'm sure it does but recent discussions have sown doubts..
After the pages of rumination and ideas, do you know what you're going to do? Can't you install a field expedient, temporary speedo to get you through an MOT without touching the non-functioning standard fit speedo?
7.8 Item: Speedometer Method: Visual Check Reason for Failure: a) Not fitted in accordance with requirements. b) Not operational. c) Not illuminated.
The manual wording is "clearly inoperative" (Mot manual Jan 2012 Section 6.3), it is referring to cases where the needle has fallen off or is wrapped around the end stop just past 140mph or suchlike. There is NO actual test of operation so if it looks like it should work, and illuminates it is a pass.
