Odd vehicle Battery Reading

[Littlewheels]

This has appeared on my LCD Screen, Everything appears to work okay, it did it whilst on The Tunnel crossing but started fine and went back to normal but it’s just appeared again.
Any ideas?

Saying your starter battery is zero, and your leisure battery is drawing 2.8A.

Has the fuse failed on your split charge side? Is the leisure battery charging when the engine is running?

Possibly a poor connection in the starter battery circuit.

If its a Fiat and the battery between the seats in the floor, check the negative connection. They use a clip on connection, maybe that has come loose. Just an idea.

Possibly interference from Tunnel electrics or thrown a wobbly due to the pressure wave you get entering the tunnel;.
A few years ago after going through the tunnel in a VW transporter had no indicators, aircon, central locking and electric windows not working. Stopped & phoned UK dealer they had no idea, restarted the engine 15 min later & everything worked.

Difficult to see Starter Battery Zero as it starts fine and resorted to showing full charge shortly after start up.
Haven’t checked fuse as all appeared well.

This is a possibility,this is a new vehicle and has some form of WiFi built into the Battery System that l haven’t yet got my head around.It occurred to me that the Tunnel cut the WiFi signal but it hasn’t rebooted if that makes any sense.
Mercedes 3.6.

I get the impression that the reason that maybe 7 people in 10 worry about their electrics is that their sophisticated panels provide far too much information.

All sorts of stuff could be happening with my 27 yr old electrical system which has just a green LED and a red one, but in 11 years I've never seen the red one illuminate and never had an electrical problem. (Imagine a Smug icon here).

Your starter battery is fine, as you saying it starts the van, but the signal to the battery monitor has not failed in your picture

What make model is the MH, and what make/model is the distribution/fusebox? If it's an Elektroblock (EBL) then does the fridge work on 12V when the engine is running? If not then check the fuse, probably 20A, just next to the starter battery. The starter battery voltage reading gets to the panel along that fridge supply wire.

Sometimes I wonder if all this stuff is getting too smart for its own good.

We need to start a petition to ban the unnecessary use of microprocessors.
