speedo

my speedo is out cause of the wheels but it doesnt explain the irational behavior like going up and down randomly lol

i belive its a sender unit of somesort that plugs into something. can anyone help and is it and easy fix as in can a complete noob install it

Have you got any pics or videos to show the problen

ill try get a vid tommorow but its similiar to this but it it happens a lot smaller click here

mine goes down then up and betewen 10mph difference sort of thing

could be a loose connection either behind the cluster or at the sensor, or could be a wire has started to mess up..

i had the same problem but mine was because afew wires had fused together behind the dashboard

Does your radio cut out 2??
Because the 1 in the video looks like its a earthing fault to me

ive had the dash out and cant see any loose wires it all looks pretty clean tbh might have to pop it in the garage as it still judders so might get both looked at

ok i managed to ake a video of the dam speedo against my missus wishes lol

bear in mind I was doing a steady 55ish not 40 as it says so calibration is out too but is it more than that?


click here

try to upload the video to youtube, cant view it properly on there

ok does it work now?

youtube link

looks like it could be a loose wire, or speedo has been opened and messed around with...
try to get another set of clocks (any e10 one from scrapyard with rev gauge) and plug them in and see if it has the same problem

ishaq

it wouldnt be that it just needs calibrating then due to having 17inch wheels now 16inch wheels but it started life on 14inch wheels?

i dont think that 16" alloys would make a 15mph difference...

oh ok startin to think maybe i shouldnt have bought this car lol

dont be put off by it, like i said get another cluster (shouldnt be more than £15) and plug it in and see if the problem is still there, if you lived closer i would have just taken mine out and plugged it in to your car just to check if it had a problem

thx bud and yeh I wish we did live closer cause I aitn gotta clue where im gunna find one of these clusters from im gunna hev to dig round for a specialist I think

i found these people and they seem to have a gxi in stock so ive emailed em for price list

Im allways a bit unsure when buying from somewhere i dont know b4

use a tyre size converter to see how much your speed has altered but if your cars 15 m out you need to look at replacing the speed sensor that’s on your gearbox it has a 3 pin plug

As long as you get the appropriate matching tyre size, increasing the wheel diameter shouldn't affect the speedo by more than a couple of %. I'm running 17s and my speedo is bang-on.

thats what I was expecting it could be I have to order a driveshaft ill see if they have one of these available too are they easy to fit? i believe it just twists out?

driveshaft are quite easy to take out but you need to unbolt the hub.. also depends which side the driveshaft. one is longer than the other, and the longer one has a braket on it which needs unbolting

With your speedometer, does it function normally, just off? Or does it hesitate, jump, get stuck, take a while to start reading, etc.

i have to take driveshaft out to get to the speedo unit? or are u confussed what thread ur in ishaq lol :p

damn i hate mechanical things lol :p will be handy if i do have to take driveshaft out as mine needs replacing so I could do both driveshaft and speedo at same time

it seems fine chris untill it gets to bout 40 then it seems to stop or get slower and slower the faster i get for example if im doing about 50 it says 40 then when im doing 60 it says 45 and then 70 is about 50ish?

something very weird going there lol I would say maybe a jammed cable but it cant be as there isnt one lol I have had the dials out numerous times and I have checked the connections and they all look good. The copper terminals inside have your usual scrape connection marks but nothing untoward i would say and it all looks intact

Well it's getting the signal obviously, but the clock itself seems broken since it gets stuck.

u think the same as ishaq then new clocks?

Yes.
