I am considering changing the 2 clock speedo in my 1991 mini city for a 3 clock one, I have read various posts before which say the wires for the rev counter are already in place even though i dont have a rev counter in my car, so is it just a case of connecting the new 3 clock speedo or will i need to wire the rev counter up. Also the new speedo is 110mph but the one in my car at them moment is only 90mph, will i need to change anything such as the speedo cable when fitting the new clocks? thanks

Model: mini city
Year: 1991
Description of problem (please be as in depth as possible):



Any non-standard parts that might be involved with the problem?

You will need the frame for the 3 clock binnacle, unless you have a dash then you just put it to one side.

There are 2 wires, 1 spade, 1 bullet, just plug them in then your away!

The 110mph speedo is a tricky one, if it was me i would swap the speedos over, take the plastic shroud off, remove the plastic dial covers then theres 2 screws on the back, undo these and it should pop out, saves messing with milage aswell.

thats what i was thinking about doing swapping them over, but then would have to dials with the magnolia dials, and the speedo in black ?will just fit the new clocks and figure out how i can use my sat nav to work out my speed, simpler option for a novice

You can always get Speedycables to recalibrate your clocks if they are out.

Oh yeah, oops.

Erm... you can get 90mph magnolia facias but there is slight differences between a magnolia 90 mph and 110 mph, think the 90 ones are aftermarket, but I have never seen a magnolia 90 mph facia in a aftermarket set, I picked one up from an autojumble at a show. You could try and look for aftermarket facias, dont know if they have started doing 90 mph's now.

Ive just read a thread in the complete rebuild section and the rev counter he has connected (looks like an mpi one) is showing double the actual rpm so on tickover is showing just under 2000rpm, Will this happen with mine ?? as i have the speedo from an spi, Also do you know how much speedy cables charge to re-calibrate the speedo or would it be cheaper the change the speedo drive thingy from the gearbox ?? Thanks

Speedy cable charge about £70 to recalibrate your speedo, but you have to take measurements; of the wheels, and how many times the cable that feeds the speedo turns when you push the car for 6 turns of the wheels.

They also do a conversion for your rev counter that makes it work with either ignition type, I think thats about £50.

Check out their site, all the info is there.

I have the same problem with mine!

Thats seem abit steep £120 to re calibrate the speedo and rev counter, looks like ill stick with the 2clock binnacle, as there are more important things to spend the money on, from the NEVER ENDING to do list on the mini

[Its a mini thing]

i bought a set of Magnolia dials off ebay, it had both 90MPH one in the pack and 110MPH one, my speedo is way out but i use my speed camera detector as a speedo so i ant botherd

as for the rev counter my mini is a 1976 car and originally had the 2 clocks, but when i fitted the 3 there was already one wire in place for the rev counter, it was the bullet connector one, think its black and white??? i then added a live wire directly from the fuse box so it worked with egnition and plugged that into the back of the rev counter, works a treat.

I have already been looking at those websites, Is re-calibrating the clocks the only way of getting them accurate or could I change the speedo drive thing in the gearbox ?

As above mate, the actual rev clock connectors look like this (on the right)



Have you also got a new dash panel to put in?

I did so I was lucky as the 'C' shape bracket (see below) I got on my new 3 gauge does not use the existing holes from the 2 gauge bracket bars that you access from the engine bay.



I could'nt even get the original bracket bars (from the 2 gauge) to align with the new 3 gauge as the holes were in the wrong place and didnt fancy drilling through it, maybe someone here has?

And getting the old dials out is easy, a few push-fit-clips



Then two screws either end of speedo cable back and the dial falls out forward



But I had problems getting the two small screws out of the speedo dial and made a meal of it!!!



So just a heads up, dont do what I done, use a pozi head instead of a phillips........

Yeh i think thats what ill do, just wasnt sure if you could seperate the speedo like that, Cheers for the advice, will have a go at doing it this weekend then

[ZED]

I was lucky with my dials as the speedo shows the right speed if I look at the km/p/h rather then the m/p/h and the rev counter is showing double!

Haha least it saves having to have the speedo re-calibrated if you can just use the kmp/h
