Electric Drop Out

[Bibbers]

We are over in Europe at the minute and our Swift Bolero 630EW has developed a fault 'again' this latest one involves the power just dropping out momentarily when connected to EHU. We only realise this has happened when go into the van and the heating/hot water/ power choice screen is flashing (as when you first plug in the EHU)
There seems to be nothing obvious that would cause this. I first though it was the site power dropping off but it's happened on 3 different places now.
I'm led to believe Swift vans are known for electric issue. Has anyone else come across this problem ?
Any help would be appreciated

Is it 12v that runs it heater if so check the erth bonding a bit of contact spray on the erth my help also check hab battery terminals sounds to me likely a dry jont bad connection
Bit of wire wiggling might just find or sort it out
The wiring harness might have a bad spade feel for a warm connection.
Had sumthing very like that on a boat I am working on it was a fault in a plug with a lot of spade conetenons
Also check plugs from 240v charging system to 12 v and fuse box terminals
Good luck with it

Cheers for that, I will have a good look around when we get back home next week.
It has also started doing it when we are on the road. Could it be a overheating solar panel as it's been roasting over here for a couple of weeks or an inverter issue.
Admittedly I'm guessing being a retired gas man as it's not my field of expertise but your suggestions seem reasonable enough
