Hopefully @Loz and @kurienp might see this and offer their knowledge.
I replaced the leisure batteries on my 2007 se along with a replacement solar panel from Roger Donaghue.
All working well.
Spent last weekend in North Wales with fridge working well without hook up.
I did notice that on one occasion after raising the roof with engine going the control panel read 0v.
Driving back the panel read 12.5A and 0.2A and I noticed the 0.2A intermittently read 0.4A and kept changing between the 2 readings.
Just as I got back to Bristol the message voltage plausibility fault appeared. I tried to delete it but couldn’t.
I messaged WelshGas and on his recommendation I checked leisure battery fuses, checked their readings, rear 14.8v and front 16.8v.
I tried the webasto heater which worked with the engine running but once I stopped the engine the panel and the heater stopped working.
The control panel will not stay on without the engine running and each time it does work it needs resetting.
I checked all fuses that relate to control panel and all ok. I looked under the passenger seat and other than the 80a fuse I can’t see any other fuses.
We’re meant to be away in September and clearly this is a problem if the control unit won’t stay on.
I went through the error code process but none came up.
I guess anything more technical is probably beyond me but unless there’s a few more things for me to check it looks like a specialist who knows the California.
I’ve had some very poor service from Heritage here in Bristol.
Can anyone help suggest my next move and a good specialist who can sort this out?
Many thanks
 
Hi,
I actually get exactly the same problem. Did you find a way to fix it ? What was wrong ?
Thank you very much for your help.

Hi Alex, Loz a member on this forum was very kind and as he lives close to me he checked everything, fuses, control panel and used meters To check. We thought we’d found the problem but no.
He then checked the earth shunt which is under the fridge and the conn was poor. He put in a stronger bolt and in fact made up another earth lead and attached it in the rear cupboard. He drilled a circle out of the rear battery compartment to get to the problem.
The alternative is to remove the fridge.
It has fixed the problem.
