Speedo has reset back to zero: Help

[MATHEW]

MY speedo milage clock has reset itself back to zero for some reason. It is the digital type found on the 1994 Griff 500.
Has anyone had this problem before and if so why has it happened.
What do I need to do to get the original reading back?
The other thing that its doing is that is resets itself back to zero every time is turn the car off.

To me it looks like its lost its capability to remember the milage from the previous time maybe memory loss.

Any help on this item would be gladly recieved.

Mine did this. Is it the electric LCD type, if so you need to change the watch batter in the speedo to fix the problem, which costs about £3,mor in my case the garage did it for about £50.

One other thing, it may resume at 0 when the battery is replaced.

My 1999 Griff has the old fashioned wheeled counter which is prone to jamming when it gets to x9999.

I'm intrigued that earlier cars had the (in theory at least) more 'advanced' digital/lcd readout.

Did they keep chopping and changing?

[squirrelz]

As far as I've seen (and I've not seen that many chim or griff), older cars had mechanical odometers, and newer ones had electronic ones. Dunno really when the change was, but suspect some time around 1999/2000.

I think if an older car has an electronic one, then the speedo has been replaced at some point.

But then I could be wildly wrong

[simpo one]

I've never seen a Griff with an electronic odometer, and I've quite a lot of Griffs! How many were made and when?

[david010167]

Mine is a 1995 Griffith 500 and has a LCD mile counter.

Its battery went at 21k miles, the first I noticed is that when I turned the car on, the counter siad zero, I wnet for a drive and the counter counter updwards, but when I turned the engine back off it went to zero again.

At the moment it shows 19xx mile. All in all the car has only done 23-24k, but the counter says less.

Weird. If I'm not mistaken that's a low fuel warning light on the fuel gauge too? Which presumably comes on the moment you've filled the car with petrol to say 'Warning - you only have 200 miles range left!'.

I think the last 100 Griffs had a digital readout.

Are your dials all original David, or have they been replaced at some stage?

For what it is worth the speedo on my late 94 Chimaera is identical to Davids,I am sure that it is the original.

[raceboy]

Me too, May 94 Chimaera, exactly the same dial set-up, and had exactly the same problem, took the speedo out myself and sent it to these people, they repaired it and reset the mileometer to approximatly the figure it was pre battery meltdown about £30 if I remember.

Got a strange thing happening with my speedo at the moment. It appears to stick at 60-70mph and wont go higher or lower. The only way to get it to read the correct speed again is to repeatedly press the odometer reset until it starts working.

I'm going to try and take it out when I get a free couple of hours, has anyone else seen this and fixed it?

Graham
PS. It's a non-digital one - 96 Griff 500.

[david010167]

Its a totaly original car (except audio), all dials are as standard. And yes there is a fuel light that pops on when the tank is low, I still do not trust it.

Don't you love it when it comes on under hard cornering when you still have 1/2 a tank of petrol

[squirrelz]

thats different from the later digital odometers.

Looks as though they started with LCD, changed to mechanical, then changed to whatever the last ones were (LCD/VFD/LED?)

[david010167]

Or it comes on when fuel is lowesh and you hit a bimp, sneeze, cry or play loud music. Just a tad unreliable, but still it does make me look for the nearest petrol station the moment it flashes.

I wonder how the digital odometer in my 9-year old BMW works? I'm sure it won't reset if the battery is changed, and any battery would have gone flat years ago. It could be a small nicad but even those die, like the one in my central heating timer!

What do you think? The only car that is standard is the last one of the production line.... All others are prototypes which is why they are so character building.

The LCD came in around 98/99 ish but many of the earlier cars seem to have had a speedo change and been retrofitted I suspect because the older ones were not available.

Weird, and typical TVR, mine is a 95 and has had no work done on the dash, so I guess the previouse owner may have requested the LCD when it was built.

I have to say in strong light, you have no idea how far you have gone. You just cannot read the numbers.

Thanks for all of that I will change the bat behind the clock then. This will be done when I change my dash for the ali type within the next month.
Only a small question though, this seems a bit of a strange way to have the milage clock running it leaves it very open for clocking.

From all the cars I have seen over the years,

First Griffith Chimeara had mechanical rolling digit odometers which had no trip counter and clicked every 10th of a mile. ( black rimmed)

In '94 (sometime to sometime) TVR fitted an LCD version ( the one you're having trouble with the battery- probably why they changed again to)

'95 revised mechanical from another supplier ( with trip counter)

Change over probably occured as a nd when TVR used the remaining ones from the previous batch ( would vary by colour of dial)
