Ok so my speedo stoped working the other day and im 99% sure theres nothing wrong with the clocks so this leaves me with the following:

The clocks are from a '79 1275GT
The speedo cable as far as im aware is from the original '79 GT A series engine
The engine however is a newer A+ Series engine

So im guessing there is some incompatibilty between the various ages of parts concerned.

If so does anyone have any recommendations on how to rectify the problem or on what type of speedo cable i need as there seem to be quite a few available?

There are a couple of similar threads running at the moment and there are some useful pictures here with a link to more info. Maybe the cable has just come adrift at the top end or maybe it's broken. I can't help if you need a new one because I'm still trying to find one that fits mine.

Lol shifty i can always count on you! But seriously you know the speedo cable ive had a look at mine and the end that plugs into the speedo, the inner bit seems to be square in shape is that right?

Should be ok, how about getting a drill on the end of the cable?

If it works then its a speedo drive problem.

If not then its a cable/speedo problem.

(See I can be sensible!!)

We seem to be agreed that the cable itself is square both ends and is a screw fit down on the block. If you look at the Minispares range for instance you'll see that there are several different lengths, so you don't want a too-short one, but an overlong one can be fed through carefully so as not to kink. The tricky bit is that if the top (dial) end is a push fit, you need the right shape cable shroud. I'm still trying

I’m using the same 120mph smith’s clocks and have an A+ series engine. The original cable on mine was the long (clubman) grey push fit ended one, and the replacement I bought was the same.
Until i had a few problems with the cable not seating correctly, but it had been working fine for a couple of years up to that point. When in desperation from having to drive around with a Speedo that didn’t work, I “borrowed” the later style white clipped ended cable for the later Nippon clocks from the 89 Mayfair.
And so far not only has the Speedo stayed working, but the cable is more secure on the back of the clocks as it’s clipped on rather than a sliding/push fit.
