Hi.
On my hybrid the voltage indicator shows around 14v when I start driving and after a while it goes down to about 12v. I am assuming it is showing the voltage for the rear 12v battery.
anyone knows why the voltage should drop? I am assuming the battery is charging when I start driving and when it drops to 12+ it means it has stopped charging or that it has reached its full charge. If that is the case, should I assume the DC-DC converted that charges the rear 12v battery from the traction battery actually is able to connect and disconnect as needed?
Does anyone know about it? I could not find any information in the manual.
Thanks in advance.
