i had to have the battery replaced today in my sebring. i took it to walmart and had it done. on the way home, i noticed that the display on the radio keeps going off for a split second. when it comes back on, the time is reset to 12:00 and the radio is set to the AM band. when the car is shut off, the clock keeps perfect time. does anybody know what is going on with the radio and how i can fix it? would a mistake replacing the battery have caused this. i had the charging system checked by another place and was told that the alternator is working ok. is there anything connected to the battery that could cause this?
