Is it constant throughout the range

In that when stationary it shows -10

10MPH it shows 0
20. 10
30. 20

And so on


Or is it proportional to the speed say


0. 0
10. 8
20. 17
30. 26

pretty consistent. The needle is sort of at minus ten at standstill!

Great you can move the needle

I will pull up so instruction in a minute

Back soon

Also can you make sure the car is on the correct tyres

 

[koalar]

For me at 6`2" the lower part of the always reads a little out because I am looking down on the needle

But the needle does commonly gets nudged when the battery gets low and the needles move violently as the car cranks

It's then a faf to put right

 

[jayartibee]

So it's just part of that procedure - move the needle to zero?

Yes

 

[jayartibee]

Yes

thanks

 

[jayartibee]

thanks

I imagined that by moving the needle by hand it would just move the mechanism rather than slip the needle on the spindle

Correct

But there is a stop

About 1:55 in the video

Take the pointer off

Put it back above zero

Rotate it into position

Gotcha - and do you need those special protective discs or can you just carefully pull

Up to you

For someone else's car I would Just cut my own from a bit of card, it doesn't have to be accurate

My own car I'd probably just wing it

Brill thanks a lot. Is the removal of the cluster easy on a 2nd gen Panda? Maybe there is a vid somewhere?

Easy but disconect the battery first
