Last week the fan belt snapped/fell of so i replaced the belt with a new one , but now when i leave my car overnight it wont start in the morning, once i have jump started the car it works and can drive but when its running,i turn on my lights and the clock display turns of :/ i disconnected one of the terminals on the battery and when i touch it onto the battery it sparks, im not sure what the problem is could it be the alternator or electrical problem......?

what car is it? theres obviously not enough power in the battery for some reason thats why the clock display goes off. is the new belt at the correct tension? sounds to me like its an alternator problem. also does the battery light stay on when driving

just sounds to me as tho the batterys nackered.

well i'd put my house on one of us being right so shouldnt be that hard to fix lol. either battery or alternator.

checked the alternator and its fine! new batteries on its way, thanks guys

did you test the alternator and battery then?

yeah
