So i switch my alternator i bought a new today and like any other problem hassle to put in in this cold *** weather anyway i install my alternator with my old battery i had to push start the car the car started up but i turn my HID's on and the car shuts off i push start it again and instead i turn my yellow foggies on i look at my volt meter and the car running the meter's pointer is in the red zone after i ran the car for like 20 minutes with my foggies on then i turn my HID's on again and the car acts like if there was a short some where and the check engine turns on for like 5 seconds and turns off again but the car running then when i turn all the lights off the meter goes up to like 13.5 voltage when everything is off what can that be???

 

more than likely i think it is ur alternater is it compatiable with the battery because some batteries wont work

 

so what can i do about it
