Hi all,

According to some sources, this problem has been diagnosed and recognised by you lads and lasses here, so I'm hoping someone has some answers for me ! :) OK, all of a sudden, I noticed my headunit display dimming when I put on the brakes...then i noticed that all my instruments also displayed the same symptoms. Then with some help (thanks Ghia) I was told to see if cruise control worked...and it didn't (as expected). Apparently there's some kind of relay thingy (or something of that description) down near the brake pedal that is renown for playing up - can anyone verify this ? and if so what I need to do so that at night time I don't have to drive around with my brake lights constantly on ! - hehe

Thanks for any info ppl,
Steve

Could be bad earth on battery, or to chassis, check tighten up and clean terminals, positive connection 2, first step check all wiring connections. Make sure you have your radio code at hand before you remove battery leads. If still happening take to auto electrician if you can find a good one.

Thanks xrhp6 - I do actually have a badly corroded negative terminal, so I'll clean that up with some bicarb soda right now !! I honestly, never thought of that, but I'm hoping that fixes everything :) Thanks again - will let you know if this is the case

Cheers,
Steve

What happens when you put your parkers on? Does this bring the stoplights on? if so then i'd put my money on one of two things:

1. Trailer plug wiring rubbing or dodgy connections in plug or boot wiring.

2. Wrong globe (or el-cheapo) globe fitted to the left or right hand taillight.

both of these problems will bring the dash lights on when you put your foot on the brake, but you probably wouldnt notice it at night!

Good luck!

Hi again all,

Sorry for bringing this all back from ages ago - but problem is still there! OK, I've checked negative terminal, but will do so again to be absolutely sure, however I've been told that this is a known problem with my EL and that it's a el cheapo relay or something that is factory fitted like under the dash near the brake - does anyone know if there is any truth to this ?

Thanks all,
Steve

Good luck!

Or how about a rear left tailight that Is full of water. Its got enough water in there to house a lake worth of fish:s6:

Ghia - what a *surprise* ;-) Nah, that problem was fixed ages ago - geez man, get with the times ! hehe. It was you who told me about that dodgy el cheapo part near the brakes actually - can you be more specific - ie what am I looking for ? It's really starting to annoy - so any help appreciated champ !

Muchas Gracias,
Stevo Supremo

Check your alternator. The Suby did the same thing just before the alternator blewup. As did the Miss's Calais.
