Thanks. Looks like I will be replacing the alternator soon then. I am seeing that cold may not be a factor. Yesterday it was 45 degrees and it still happened. Alternator kicked in after 4 1/2 minutes. I do have a Creader VI OBDII scanner and it is not detecting any codes. What did your repair shop charge?
