T6 EHU partially working... 240v kitchen socket working ok but not charging the batteries

[Baldrick]

Hi kind folks of the road
I’m touring the Highlands at the moment. Currently on EHU and the 240v (kitchen unit) socket worked last night, unfortunately the control panel didn’t show that the batteries were charging. By morning the battery level echoed this. Both breakers are fine - still active/red.
I’ve searched on here for a solution but possibly my search phraseology didn’t cut it. I do have solar, so it’s not the end of the world, but the starter battery is 9 years old, so it welcome’s a charge whenever possible, and that doesn't get a share of the solar, currently anyway
Despite being an avid reader I can’t recall anything for this specific fault, on the plus side I do have every fuse known to Man, well, California in a ‘really useful’ just in case box…
Many thanks in anticipation
‘Winston’ is a T6 MY’67 (2017) build with every option at the time (yet still 5 blanked out buttons on the dash - which may deserve it’s own thread, if there isn’t one already)

Open the rear battery flap, bottom of rear wardrobe. You don’t need to touch the battery.
Above the battery is the Mains Charger.
On the Left side, towards rear of vehicle, is a black , electric kettle type plug.
Make sure it is properly seated in its socket.

They are prone to coming loose through vibration.

Many thanks WelshGas, as always. If I had a hat to hand, I'd take it off to you. Alas the black, electric kettle type plug was firmly in position although I did remove and reinsert to double check. However, armed with the extra info I did some more digging and have a few other avenues; fuses it seems may be my next journey, the 80 Amp one looks ok but I'll test it with a multi meter tomorrow to be on the safe side. Then the actual battery chargers fuse. The voltage is dropping throughout the evening according to the Solar Victron app so it's highly unlikely to be the multi-function display 'hanging' because that shows the same degradation overnight then rises again as the solar takes over. I see from your exchanges with Fraz back in 2021 and later on the same thread with Thomasamoht that there's a small glass fuse onboard the battery charger, behind said 3 pin kettle type socket. I'll endeavour to report back. If not, I need new leisure batteries anyway and have been doing some digging on LiFePO4 batteries as replacements which will need a new charger for them in any case. Either FogStar or Roamer, may fit the bill without completely breaking the bank - also on my list of research on here, hopefully without pestering anyone. Thanks again.
