Only thing I could find is there is like 7diffrerent charging modes for this system and the one matching the reading I’m getting is for freezing temps well I live in central Fla so I know it’s not that cold
Hello my 5.3 has 54000 miles currently.When I got the truck it charged normal at 14.7v then would drop to 12.5 when the computer felt the battery had good charge. all the sudden it started charging at 15.9 and drops to 13.9 or 14 does anyone know why? I put a brand new battery in it also.
