i tried startin my car today and it wouldnt even crank over..i heard a little buzzing sound comin from inside the car and the battery light on my cluster was blinking..i checked my battery and its at about 12v which is good enough. any idea on wha it can be

 

A battery may read 12 volts under no load, but can't produce the current required to crank the engine. Check the voltage while cranking. If it holds near 12 volts, check your cables at both ends for good clean connections.

Overall, I think your battery is weak.

 

i checked it and its ok.. any other ideas?
