electric little things

Hi,here I am again with my stupid questions.Can somebody answer me about that switch which turns the red light on when brake fluid level is low I think it is marked like this on the instrument panel: (O) Do you know what I mean?
Anyway,even when the brake fluid level in my car dropped due to another problem,the red light did not turn on.
I would like to ask does the switch closes the -(EARTH) pole or
+(positive) to lit the light?If it is negative(-),than it is similar to the switch used to turn the handbrake warning light on(!)
Can you give me some help regarding this little which drives me crazy,I would appreciate any kind of suggestions
Thank you

the switch is positiv (not 100% because I do not have an 146 ).
the problem is normaly the earth at the fuel tank connection (rust!). If you don´t find the reason demount the switch and test it outside the tank with a working earth.
maybe only your light is broken!

Kind Regards
André

Hi, I have alfa romeo 145 1.6 boxer engine. Couple days ago I tried to start the car in the morning and the ignition was fine, but after the engine became warm rpm-s still were on 1400-1500. When I pushed gas pedal, rpm-s go down but the engine worked unstable, rpm-s hesitaded from 700-1200. Some people said that the probem is airflow sensor. Can anybody help me about this ?
