No 12 volt unless on Hook up

[Bailey58]

Noticed when we stopped en route we have no 12v. Display dead and no pump, lights etc. I've checked all the fuses on the mains board which are all fine. Everything works on hook up so I assume there must be a fuse or a reset button somewhere. I can get to the two leisure batteries without finding anything while the engine battery is somewhat more inaccessible especially with carpets and dog in the way. I seem to remember a mass of wiring and stuff when I last saw it so is that where I should be looking? As we're on sites between now and home it can wait but any suggestions welcome.

Must have very strange wiring if all the 12v stuff worked with EHU.

Bailey works in mysterious ways, or not!

Now that you have it all working, if you want your batteries to last I would replace that charger with a proper one.

I would have thought that on EHU the power supply would provide a nice steady 12-or-so volts feed? I know mine does.

Never been a problem with the solar keeping them topped up and the occasional hook up over winter. The charger is integrated in the mains unit although it appears to be this metal box which slides up and out at the back although there are a couple of permanent wire connections.

If you have a good multi-stage solar controller and hardly use EHU it will be OK.

Excellent news. Onward and upward
