speedo on 94 chim making clicking noise

[jonny car roll]

the speedo on my chim works most of time but when working makes a clicking noise every 3 seconds or so. sometimes it stops working and then will start again for no apparrant reason....very eratic. is it the cable or speedo any ideas and how hard is it to replace?

They all do that. It is because, although the speedo has had the trip removed, the internal trigger that drove the trip every 1/10th of a mile is still there. It's that that you hear clicking every 1/10th mile

really! i'm learning every day. did the later cars suffer the same problem and if i wanted to stop it i'm i looking at a new or later speedo?

[poorpeet]

I think the later one have a digital trip. Not sure if you can fit a later speedo although I dont see why not.
I did read some thing a few years ago about how to stop it. It wasn't that straight forward though so I never bothered.
Have a go and let me know how you get on.

thanks for the advice i take you have or had one that did the same?

I've heard the same 0.1 mile story explained by poorpeet but I'm not certain which speedos it relates to. Original speedos had drums to record mileage. Briefly they became digital but returned to being mechanical in the mid-nineties. In very late cars, approximately 2000 onwards, they became digital again.

Mine's one of the commoner mechanical speedos from the late nineties and it goes through phases of mechanical noise then back to silence, although it's not a click I hear.

Well, I never knew that.

All mine from March 98 on were digital? (me 95 was mechanical)

...but now I think about it, me 98 was also mechanical!

Mine was built in mid-1999, July I believe, and registered in August and it has the mechanical speedo. I thought they'd all been mechanical until I started looking at them and found a few (around 94?) that were digital (mainly based on reports of the counter returning to zero because the internal battery was flat). I've yet to see a very late car (with perspex headlamp covers) without a digital speedo but I've seen 2000 onwards cars with the original headlamps and digital speedo.

As an aside, I'd like to see a timeline of the changes made over the years. I've got a couple of details like boot hinges and rear lamps down to a few months, the problem is I've heard stories of factory visits where cars being produced at the same time had different lights etc. so it might be impossible. I suppose the other problem is some cars were registered immediately after manufacture whilst others laid around (in dealer stock?) for a while first.

Mate, they built 'em with whatever bits came out of the parts bin that day!

My speedo was intermittent. Since driving all the way through France and back it's fixed itself! I put it down to lack of use. Good excuse for you to drive the thing more
