[C320-list] Electrical issue

[Jaime Borrego]

Had a battery issue earlier this year - bank 1 would not charge fully and would completely discharge by the morning. I had both banks replaced and now they are holding and charging properly.  

However, my stereo now doesn’t work - I just replaced the stereo a couple of weeks before my batteries stopped working - could these be related?

Thanks
