the other day while driving my 01 ss home, the battery loight came on and the volt gage dropped to zero. then the security light came on. I drove it straight home not knowing if something in the charging system went bad. when I got home I put a volt meter on the alternater, and it showed around 14 volts and the battery was taking a charge. So i figured the charge system was working. I then noticed that I could not turn my radio on. the top of the radio would read security locked out. I then tried to hold the disp button in on the radio to get into the vehiclemaint settings. that would also come up security locked out.
has anyone else had a problem like this.
