Battery charging
I have replaced both batteries on my E55 AMG and new 150A alternator with regulator. Car has done less than 10 miles since and now I have the convenience functions disabled and intermittant stop car warning again.
my OBD reader is sometimes fluctuating and then read over 400,000Volts!
Pulled the car up at home and the Icarsoft scanner was telling me batteries are at 14-14.2v. Multimeter on the batteries themselves was at 13.7v and slowly dropped to 13.3v but the icarsoft still said 14.1v
any electrical experts able to suggest what the fault could be before I get the hammer out?
