Using bits &pieces i have fitted a coolant level alarm to my MGF. It is very simple 12v+ ign operated supply -- LED sw -- Buzzer -- Reed sw operated by magnetic float -- earth. The systenwell but is too sensitive , bumps & fast cornering causing unwanted buzzing ! Will a capacitor & resistor in series giving a 15 sec delay solve the problem ,if so what values should they have &where should they be fitted . Any help much appreciated .
