well this is what i just did i took a multimeter and hooked it up to the terminlas and got a reading of 12.2v with the car off then started the car and got a signale of 11.9v and everytime i turned something (Lights, RAdio) the voltage on the battery would go down i think it is my alternator but for some reason the battery light dosent show at all and when it was alternator problems last time my battery light was on. so im not quite sure is there really anything else that could be wrong
