I own a 2000 model Nissan Maxima. The problem is, as am driving, the batterie, brake, seat belt just all lights in the dash board began to flash then the head lights and radio will go dead. And car began to choke then engine stops. The batterie is now dead sometimes you jump it to start I have gone through 4 batteries already and also changed the alternator. Please, what can I do.
