Speedometer and rev counter gauge stopped working

[cross.damien]

Hi,
I have a 2004 Mk6 90 t350 jumbo transit. Went to shop, parked up van. When i started it again. the rev counter and speedometer gauge were not working. started and stopped it a few times but still not working.
Anyone any ideas what is wrong here? The fuel gauge works fine, and all the lights etc.

Cheers

Mine did this once, not long after I'd got it in Nov 2010. It had stood for a couple of weeks in very wet weather, and it felt a bit damp inside the cab. No speedo or revs when I started it. Drove 10 miles to petrol station, filled up, and it was fine after that. It's never done it again since. I put it down to a loose connection, perhaps made worse by damp conditions but I don't know anything about electrics so that's just an uneducated guess.

I replaced the speedometer sensor in the gearbox, still no revs and no speedo working.
Im out of ideas. I might take out the clock and check connections

i took the battery lead off over night, cleaned up all the earths, took the two sensors out the gear box and cleaned. still nothing.

Have you checked the fuses?

friend of mine has a t260 swb and his van does this. it seems to be intermitent. be interested seeing your replys. he wanted to try the clocks out of my van but i dont fancy striping mine all down aswell. especially when mine seems fine.

randomly enough the light on my radio never works. but last night i started it up and the light came on for say 5 seconds. enough for me to go ohh look at that lol. then went off again. strange.

At the weekend i decided to take out the speedometer. I had already previously changed the sensor in the gearbox, but that didnt solve the problem. When i took out the speedometer clock, in behind it were 2 fuses. One of them was blown - 15amp. I changed that. Plugged out the clock, plugged back in, started van, and it is now working.

Hope this helps.

I dont know how it would have worked intermittently if it was the fuse that was wrong. Doesnt make sense

I'm having the same problem with my instrument cluster.

It randomly goes off.
Rev counter drops out, Speedo drops out, temperature gauge drops out, mileage display displays dashes, fuel gauge works fine.
I've found that when it all drops out if I thump the dashboard it all comes back to life......for a few seconds, a few minutes, a few hours or a few days.

Some days it works fine, but today it's been an absolute pain!! On and off constantly every minute or two.

I've looked all over the internet over the past hour trying to find a resolve to this problem. It would seem that NOBODY has an answer!!

Everyone is stabbing in the dark as to what the problem "may be".
I have read that stripping the clocks out of the dash and cleaning with WD40 is a definite NO NO!
It would appear that once the clocks start doing this, they're buggered and have to be replaced, or send your unit to a company in the UK who will repair the unit and send it back to you for £99.
Fitting a second-hand unit from the scrapyard is a no go too as the unit has to be programmed to the ECU.

This is crazy.
Is what I've read true then? The instrument cluster is buggered and will need to be repaired??


*****EDIT*****

I've just found this on Youtbue......I'm thinking this is the problem!!!

COmmon problem for the mk6 digital (hybrid) cluster to fail.

You can fit a used./second hand one. Transit mk6 instrument cluster don't require to be programmed to van

Hi guys,
A common reason for the dials to stop working on the dash is the electrical switch on the back of the ignition barrel. They are less than £20 from fords and fail all the time.
I suspect this is why the problem is intermittent for some of you!
I hope this helps.

Regards,

David.

Just joined the forum to say...
David you are a legend.
Walked out to mine and pushed the key in a bit while running and sure enough the RPM started displaying. I knew it was something silly as the scan tool could see the RPM's fine but nothing on the tacho.
Thanks again.

Luke.
