Remember the imbilised E34 with the airbag light?
Well the problem is back and now permanent so I am in a fix!

Radio went off while driving home so I started
checking what else was out...

No wipers front or tailgate
No horn
No glove box light
No drivers side rear window movement.
Its a UK car and the relay is clicking
but no drive may be red herring?
No instrument cluster oddo display at first switch position.
No radio
Air bag circuit fault light.
Alarm light on dash as if no ignition circuit.

Powering across to a fuse relating to one of the
above under rear seat or hood brings it ALL up OK
Radio wipers glove light etc.Car will start while bridged.

I have swapped ALL the relays under the rear seat AND
under the hood with the same from her E34 sedan to
no avail.

I suspect the alarm imbiliser is what is holding it off as it
thinks there is no valid ignition circuit.
Several rapid links to turn all on a few times and it starts
unbridged.

The under hood link for the rear power is OK and
feeding main rear distributor under the seat.
I think it is under the hood somewhere?????

SO GUYS AND GALS:
WHAT IS THE COMMON FEED FOR THE ABOVE!

Yours grounded and desperate!
