My car has a new alternator, new battery and it recently started acting up. I notice MOST (not all the time) of the time when i am at a stop sign or red light and have the signal on the battery tends to drain. Not jsut by a few volts but goign from 14v down to 9v. Once i let off the brakes and the car starts moving it goes back up to 14v. Why does this start happening? Itl ooks like when the car isnt moving it doesnt charge back up but why is it doing this now it never did before?
