I brought my car in to resolve an electrical system charging issue. The problem was found to be that the alternator was not working properly. Service Street installed a new alternator. I took delivery and all seemed well. While driving later that evening, my "Battery", "ABS" and "Brake" warning lights all began flashing. I returned the car to Service Street. Their analysis concluded that the "new" replacement alternator was defective and they installed another one. They tested, and retested, the second new alternator before returning the car to me. All is well now, but in the end I had to make two trips to Service Street (as well as curtailing my previous evenings travel) due to their installation of a defective alternator (overcharging my system). The matter was handled in a courteous and professional manner but I wish that the first replacement alternator had been better tested.
