ok guys i just bought a digital multimeter and checked the voltage across the terminals of the battery and it read 10.57 V which which is low. should read (11.5-12V engine off)(13.5-15V engine running).....so what my plan is to get the car boosted again and with the engine running check the voltages again (should rise)....let it run for a while and check the voltage then put a load on it (lights on, radio, etc).....it should drop a lil but then rise again....if it drops and continues to drop then that mean my alternator isn't charging my battery and is faulty correct???? any opinions?
