Hello from germany! I´m not new in this forum as reader, but as writer.
I have a modelyear 2009 Flying Spur Speed, what a great car.

But i have a big problem with battery system. Booth are new and now i find out that one of the problems (discharging system in 1 day) comming from DVD Changer.

i have checked fuse by fuse with "amp hound 2" and see that the quiescent current from rear entertainment is 630mA. after disconnect DVD Changer is it zero.

But i have a question for loading current.

Can everyone check at his Continental ( engine running) for me? When the engine is running i have directly at right (starting) battery around 14,6volt and at the left (comfort) i have every time around 1volt fewer (13,6volt).

I know, that the starting battery is charging every time first and than the comfortbattery. But interst for me is, is the difference 1Volt normal or i have a problem with the system.

Thanks

 

@dahpe ,
I believe that you have posted in the wrong thread.

EDIT: I now see that dahpe is a spammer posting hidden links in posts, makes a post, then comes back later to add links.
Bye Bye @dahpe

Thanks Johnny. That Was not an answer to my question and not a help for my problem.

I hope anybody can check this for me at his Bentley.

Hello Johnny ,
hen you check this for me, please check also this.
when engine runnig i have at the comfort battery ( All cables!) Around 13.5V

At the start battery and to the magneticswitch 15.2V ! After magneticswitch ( cable to the comfort battery) 13.5V.

Is this correct?

charging from alternator does not go directly on the starter battery - it goes thru dc/dc converter / transistor so the voltage is different.
