Hi I wonder if anyone can answer why my interior lights ie kitchen bedroom etc go off when I unplug from EHU. I believe I have two leisure batteries and wonder why they don't kick in. Is there something I don't understand??
Have no idea where the leisure batteries on the vehicle other than knowing we have 2.
We are only now feeling confident enough in the vehicle to start asking questions . Where might the leisure batteries be located ?
In our van everything other than the two square pin plug outlets runs off 12v, it is charging while the EHU is attached. However if you unplug and have the switch OFF then you get nothing 12v, it must be ON. If your's is ON and stuff still goes off then it sounds like your battery is not holding any charge. Is there a charge meter on your control panel?
Leave it on EHU for at least 24 hours with everything electrical that you can turned off, then unplug and see if your batteries do any better.
How it's supposed to work is that everything apart from the 13A mains sockets work from the 12V leisure battery. That's the lights, water pump, heating controls, water heater controls, fridge controls etc. The power for the heater, water heater and fridge come from gas or mains electric. So you can park in the middle of a field with no mains hookup, and still have lights, keep warm, cook a meal and have a hot shower.
When plugged into the hookup, a mains charger fills up the leisure battery and keeps it topped up. If the leisure battery is not working the charger can provide a 12V supply to keep the 12V items working.
So starting from basics, there should be a switch on the control panel to turn the 12V items on. If that's on but no power, there should be a big fuse very near the leisure battery, worth checking that. If you don't know where the leisure battery is, that's the next problem.
You need to find out if the problem is that the leisure battery is flat, or the battery is ok but there's a problem with the wiring - bad connection, blown fuse etc.
By the way, I think this thread is posted in the wrong place, this section is for explanations of motorhome jargon words for those who haven't seen the word before. Maybe Jim could move it to somewhere better.
