hey guys I have a 98 cobra and I was wondering what is normal battery voltage reading when the car is running... my car from a cold start hooked up through an ultra gauge it reads 14.10 to 3.76... when the cars warms and is at normal operating temps with just normal driving conditions it drops and reads anywhere between 13.36-13.80.. but when I put on the headlights and turn on ac it drops down to 12.77-13.46.... is this normal. what is normal range for these cars ... I have a new battery and new motorcarft alternator with less than 300 miles each in them..
