Electrical Help
My ZX TD 93 has developed over the last couple of days an electrical fault. I haven't done any investigation yet I thought I'd bounce some ideas from here first-someone might know the exact fix!
When I press the brake pedal with the headlights off my brake lights illuminate-but so do my sidelights!! The sidelight bulb in the instrument panel illuminates also to about 50-100% of it's normal intensity. Obviously lights that flash as you brake is potentially serious.
Worse still when my dipped headlights are on my brake lights are permanently illuminated, when you press the brake pedal they get a little bit brighter but are constantly on. Again, not that safe and also begging for a tug from plod.
My initial thought is an earthing fault but I could be way off so I thought I'd ask if anyone else has experienced such a fault.

Hmmm...I DID fit a replacement brake light bulb last week in the right rear cluster and I've only noticed the problem since then, kind of coincidental....-I am sure it was an identical replacement I did a quick visual check when I swapped 'em over but it was dark at the time. I still have the old one (don't ask me why the hell I keep blown bulbs) I'll have a look when I get out of work, I'll feel a right tit if it is that but I'll be glad if it's such a simple fault:-)

There is a connection from one brake light to the side light. This is caused by the earth coming off. Remove each bulb in turn and check the pedal again. when the fault goes away, that is the duff side. clean the lamp holders up with wet and dry and check for a good earth connection through the loom to the bodyshell.

I had a look this evening the new buld I put in seems to be single filament and of the same type as the blown one, but it's presence is what is causing the fault. For the time being I have removed it-better just one brake light than permanently illuminated brake lights and headlights that flash everytime you brake...

Guru, check the lamp holder as I had a problem in my Xantia estate,although only a single filimant lamp is reqd a double filimant lampholder is in the loom.
The car failed the MOT and the garage thought they would do me a good turn and replaced the lamp to pass the car,but what a runaround as I was chasing a bad earth,but once the double filimant lamp was in place everything went back to normal.
