I think i have an electrical shortage some where but i am not sure.with my car in motion, as soon as i turn the the head lights on the cd player cuts off, then comes back on, this happen several times.The radio doesnt store the preset stations, the clock not keeping the correct time, all this when the motor is turn off.And finally while driving, i turn the light on, the was a sudden jerk on the car and a lost of power. The battery just got replaced at the dealership, becaus they thought my battery was weak, now i think they replaced a good battery.Anyone with any advice will be very appreciated.Thanks
