vectra 2002 - vectra abs light on and all dials not working - confussed

hi all

i was wondering could anyone help me i have read some topics on this but dont seem to have any answers posted as to if it worked.

my vectra 2002 has some problems when i drive it the abs light come on and all the dials stop working at the same time the reversing lights stop working as does the rear demister and my milage stops going up. there r time where i could drive 10 miles befor this happens and other times where as soon as i start the car it starts happening straight away. i have taken it to 2 mechanics and both have said it could be many things ranging from the altanator,sensors,abs cpu and bad contacts. i have checked all fuses and wiring and all seems to be ok and there are no oil leaks.

please help if anyone can

Diesel or petrol? Engine size?

Intermittent electrical fault means corroded wiring - probably at some plug, or a major earthing point, or a wire shorting, or a fuse connection corroded or or or... You need an auto electrician and not a general mechanic who has little clue about electrics..

It is unlikely to be the ABS ECU - why should it affect everything else? The answers you have been given show the people you asked are not competent to deal with it.

Did the mechanics actually check the alternator output, if so what was its output at idle and at 3,000 rpm?

If not, can you do it/get it done?

Do the lights come back on if you push the dials in lightly?

I'm more concerned it is OVER charging. It should put out about 14.5v, but I have a feeling we'll see more than that when tested, especially at higher revs.
