Electrical Problem

[Cormac]

Ive got a 1996 Citroen ZX volcane.. 1.9td

 

This problem has started out of the blue and I'm puzzled... you start the car up and alls fine.. when i press the brake pedal the battery light comes on and the radio will go off wipers wont work either.. take my foot off the brake and the battery light fill flicker a bit then go out and the radio will come on again.. while the battery light is on the rear brake lights don't work.. or the indicators.. the headlights work fine tho..

 

Ive changed brake bulbs but no joy

 

I'm thinking a dodgy earth somewhere but were do i start looking??

 

puzzled..

 

cheers for any help you can offer..
