I was just reading on a Cadillac forum where somebody had alternator issues and his traction control, stabilitrak, etc. lights were coming on for service. It reminded me that I did have a message to service my stabilitrak about 2 months ago. Looks like ill be looking over the alternator connections this weekend.
MET/EET degree here, i understand voltage and current just fine. up to 15.5v is normal for charging depending on state of charge and battery temperature.
