All repairs to your motorhome should be carried out professionally by an authorised motorhome repairer and by an authorised repairer for your make of motorhome chassis. Do not attempt any of the repairs yourself.

I happened to have a pretty simple solution to my problem, at which point I started analyzing and researching it in a very complicated way. When the motorhome was connected to 230V the motorhome was not charging the motorhome batteries. Of course I thought I had faulty electronics, a faulty charger, a disconnected cable… In the end, all I had to do was reset the circuit breaker on the 230V, which had accidentally tripped while putting things in the locker.
