Hi all,

bit of an issue, I got round to fit the s80 LSD gearbox in the car, but after the gearbox change, speedo has stopped working,
I swapped back to the original speed sensor and it's the same, no reaction on the speedo at all.

Any ideas on the issue and what else I can look at to the speedo working again?
Thank you

I would double check the wiring for power and check the pins to make sure they are making contact.

thanks mate, I've ran a wiring check from the speed sensor cable pins to the instrument cluster and it does have voltage reading on the wiring,
the speed senor is also giving out voltage reading on the multimetre.

I can only try and change the instrument dash / speedo itself to find out. currently trying to source one.
Not sure what else to check, speedo worked fine before i done the S80 LSD gearbox swap,

appreciate any more advice on this.

thank you
 
I think the speed sensor that mounts onto the gearbox might be ruined.
thanks guys, well i've tried both my OEM and the one that came with the S80 4.7 LSD box, both speed sensors in the car speedo isn't working. my old speed sensor was working fine before i did the gearbox swap... i am abit unsure why it's stopped working now after the gearbox change.

anymore got any spare speedos i could try plug it with ?

thanks guys!

Now, I feel like the wires got stretched out and ripped somewhere when you did the gearbox swap. The chances of both sensors going bad is very very slim.

yes it's the speedo itself stopped i think it's actually the motor on the speedo that's gone, I've ran a wiring check on both end of the wiring from speed sensor all the way to the wire into the dashboard. all have reading so what else can be apart from the speedo itself?

so does anyone have a spare speedo / cluster around i can try it to? or any for sale?

cheers
 
any one have a speedo for sale ? please PM me with details

Cheers
