MultiPlus 12/800/35-16 Not charging leisure or inverting

Hi,

After some help! I've got a MultiPlus 12/800/35-16 on my boat with start and leisure batteries. It has worked perfectly in the past but recently it is not charging the leisure battery or inverting when I remove its power source. I've charged the leisure battery with a separate portable Victron charger so I think the battery is ok. I've got a fuse between the MultiPlus and the leisure battery so I've changed that. I've got a SmartShunt on the negative of the leisure battery so I can accurately check its status.

Any further troubleshooting ideas?

Thanks!

@knotty Unplug the Multi from the raspi.

Just to check if the pi is sending out the wrong signals.

Hi,

I've put a new leisure battery in and still have issues. I've charged both batteries using a standalone Victron charger so I know that they are good. When I disconnect the power from the Victron it just dies and I get an error on restarting 'Alarm Low Battery Voltage'.

Please help!
