12v power

Just bought my first motorhome 544, and trying to get the 12v power to work.

Battery is fine, but not reading on the battery 2 rocker switch, i take it battery 1 is the engine battery, that is showing.

So i have nothing working on the leisure battery.

There is however, 2 kill switches (red plastic things) one on the front of the cab inside the driver door, and one right next to the battery, next to the driver seat.

What does each one do and what position is on for each of them?

Also any other ideas on why the battery isnt showing on the dial

Thanks in advance

Ian

If as you say the battery is fine then the isolation switches would be my first examination. Is it possible there is a large inline fuse near either battery?

There is an On/Off switch on the Electroblock Unit. Check that.

I assume that your vehicle is a Hymer 544? what year? is it left or right hand drive? A picture or two would be helpful.

How do you know that the battery is ok ? Did you test voltage with a multimeter?

Trace the cables from the leisure battery the negative connection will go to earth somewhere

The positive cables may go to the red kill switches you mentioned

If so then you can turn the one on that the cable you just traced goes to and then try your domestic 12v power

The electroblok mention is a power distribution box fitted to many european campers

Comes in different sizes and models (they tend to be blue in colour with a white face plate?) they usually have a built in mains charger and a load of fuses on the front plate

I have charged it and checked it works, so its not the battery.

LHD 544 was UK N Reg 1995.

Just got it and its our first motor home so dont know much about them.

There is a red isolator switch next to the battery and one on the cab front, but i am not sure what position they should be in.

Usually push on and pull off.

Welcome to the forum Ian - that's all I can say to someone with electrical problems (not my forte) but you're in good hands.

I was going to encourage you to put up a pic or 2 but that facility may not be working at the moment (certainly isn't on the enhanced mobile version I use on my phone). But usually a picture really is worth a thousand words.
