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

@Paulro , if the fuses are all good, are you able to check one thing please - behind the rear leisure battery (it is really behind the fridge) is the earth shunt. You may need to see how to access that from the battery compartment. Could you check if that is ok or not. It may be loose or not making proper contact with the ground. If you are able to reach it, take it our clean and retighten.

Also, @Paulro , remember there being a manual in the VIP section explaining on how to check and fix the earth shunt issue. Do see if you can find that.


On my phone right now so not convenient to check.

I can’t get to it from the battery compartment or through the cupboard next to the fridge. To access, the fridge needs to be removed.
This morning I attached my hook up mains cable and the control panel would not come on.
The panel works when the engine is running but, even though the switch bottom left goes to red, it won’t start up with the ignition on and without engine running?
So the panel only works with engine running and each time it needs resetting date/time etc. Once engine is switched off the panel goes off too.
