yesterday i was driving my 94 gt and at stoplights the voltage meter would get real low and the tach would jump around from 1-2k even though the engine was idleing steadily. now there is no battery power at all and when i try and use the keyless entry the anti-theft box in the trunk starts ticking. say, if i try and turn my headlights on(btw they don't work either), the ticking will stop, and if i turn them off the ticking comes back for a few seconds. the battery is only 2 months old so i really doubt it has already gone bad. this same thing happened the other day, but the power came back in about 5 minutes. now it is not coming back. anyone know what is up? help quick please. thanks.
