306 stoplight

On the way back from work today the stop light came on, but only very dimly,
when stopping and letting the engine idle it would disappear (alternator not
giving full volts at idle I assume) Could anyone give me an indication as to
why this light would be dimly lit?

No other warning lights have come on?!?

Cheers

This is a bit confusing stop lights are at the rear of the car how did you
noticed these light coming on? Maybe you mean the charging light came on
especially as you seem to be linking this to the alternator.

STOP warning light in the middle of the dash!

Sorry if I didnt make this clear, kind of figured something out though, its
linked to the engine fans and the fact that both of em are stuck on when the
engine is running.

 

Somebody had the same problem some time ago and this was my
reply. Never heard/got any reply so may of helped or
possibly another piece of useless info???

I had that problem with my 306 Lx D. As others have said it
is serious WHEN it comes on with another indication (water
temp or oil pressure) in my case there were no other
problems or indications. It turned out to be a corroded
connector on the water temp sensor. There are two wires to
the sensor one is for the temp sensor and the other one is
an over temp switch to earth which will bring on the STOP
light, this was corroded and was some how going to earth and
intermittenly putting the light on. The pin and the
connector corroded so bad that the only cure would be a new
sensor and connector. A new sensor is not a problem but
the connector (blue IIRC) is only available in the form a
new wiring harness at some horrendous price, needless to say
it has not been replaced, a visit to the scap yard for a
connector will suffice when convenient. The water temp gauge
has been working Ok for last few months and the STOP light
has not come on when it shouldn't.
