Hi guys.I only know basic mechanical knowledge so wondering if anybody can give me some pointers, this morning I realised that my battery light stayed illuminated on my dash. immediately i thought it was my alternator, so i drove to work with no music , blowers, lights ect, occasionally the light would go off and flicker then illuminate again. mainly staying on, checked all the belts ect everything seems ok, revved engine while full beam was on, no dimming of lights ect, no erratic noises coming or have been from alternator. everything seems normal execpt the light on ! kept engine going and disconnected battery and engine dies ( i know bad practice). any ideas (Will the car will be capable of doing a 12 mile trip tomorrow ? as i cant get doing anything untill friday) thanks for any help!
