I have done welding on my 6 I just disconnected the battery both terminals and earthed as close to my weld as possible not had any problems with any electrics after.
However I have heard that you should disconnect the ecu and battery as there is a possibility to damage the ecu. Maybe ecu or circuity in the clocks got fried.

Thanks guys pulled out & tested every fuse in the box with continuity tester ...
Tried Shunt fuse & removed

I really don't know if the battery or ECU was removed to be honest ?...but I'm wondering could the ECU be damaged ?
Would that cause clock Probs ?
The car starts & runs fine ...everything else on cars 100% fine ...
We've tried everything we know ?

Also tried new clocks ...

Two of us have just finished trying to sort it 5hrs ...no luck ...I'm thinking ECU ???

Tried Earths

Does a DTA ECU run the dash ?

the ecu has minimal connections to the dash, so unlikely, yes through the bulkhead.

Sandy just said 100% not DTA as only Rev counter control through that ..
He said try the alternator ...go careful of disconnect all the wires & start it & see if anything appears on the dash ..
He said If reg has died, it could pull down the dash power ?

I believe though that the alternator charge light does come on & go off on the dash when revved !
Will willingly try it tonight though ...

It's got to either be a earth or cable power supply I think ?

Big thank for ideas guys

PS Mei haven't tried the Bulkhead connection yet ...have taken it off 3-5 times when dash was going in & out though ...ill check under the Driver side wiper in scuttle later also ...good shout ...just in case wiper lever has caught something?

linkage wont have caught it but its easy for the plug not to do a decent connection, the two corner bolts need to be done up then the plug pushing home firmly and the middle bolt nipping up.

There are 2 plugs under the glovebox, make sure these are plugged together tight.
Most of my dash didnt work after a matrix change and it was these 2 causing it.

Not the best pic but its all i could find at short notice borrowed from the matrix removal thread.

I had a similar problem with another car a few weeks ago, the dash wasn't working at all apart from coolant temp. Fuse 25 is the one that controls this (I think) and so that would be my first port of call. Check the connections for the fuse are actually getting 12v if the fuse is ok.

My problem was slightly different as something was blowing this fuse repeatedly and the dash wasn't working. Turned out the wiring loom had been butchered so one of the 3 wires that the fuse powered was shorting somewhere, blowing the fuse. I chopped it off, fuse stopped blowing and the dash started working again.

Does the LCD light up but nothing display?

He said he didn't take it out ....

Had a little bit of a result late last night ......made a school boy error & stupidly checked the fuses inside with them in place with a continuatity tester ...ove course they beeped ok ...but you shouldn't do that as they will show ok LOL

Anyway fuse 25 =5amp was blown & after replacing I seem to have most of my dash back apart from my Rev counter & fuel gauge ?
Can't check the speedo ...until Sat ...

Even got LED mileage & trip now !

Sadly somehow my mileage clocks read 000007 & my trip reads 0007 also ....so lost my Mileage ?????

Also the oil temp on the bottom right goes up & self checks when ignition goes on to check ...but sadly even after engine running for 30mins doesn't give reading...

The Rev counter needle is also gone upto 1000 & is stuck & vibrating even with engine stopped ?

I'm hoping it's now the Clocks Blown ????
I'll try the spare set tonight ...fingers crossed Thumbs up

It's my fault for fitting a second hand on/ off with I didn't realise was faulty & turned on permanently......basically he was welding with battery connected !!!!

I've asked him again & hes 100% told me he disconnected the DTA ...as it was when I picked it up ....hoping he did ...oops
