I live in Portugal and I do not have any Arsilicii helpdesk where you can help me, so all your help will be greatly appreciated.
Some time ago I had a problem with the cell battery that almost burned the positive terminal of the unit, however, after cleaning it always worked well.
Last December, when I had the motorhome connected to 220v, by lapse I started the engine without disconnecting the plug and when I realized that I immediately disconnected the electricity plug.
Coincidence or not, since then I have a weird minimum problem on the AL320RC drive.
When I connect the + and - wires of the cell battery to the respective unit contacts I get error and it does not work, however moving the + wire to the next terminal works.
I know this should not be normal operation so I needed your help.
Also attached photos so that they understand my problem.
All your help is greatly appreciated since I have nothing that can help me in Portugal
Thank you very much
