Don't know the answer to your particular model, however, I had a Hymer 700 and you had to press two buttons to make things work....maybe you are missing a switch or something simple like that....
Don't you have a manual??
No manual, I'm afraid. Many thanks for the advice though; it's much appreciated.

I have a K reg Hymer and if yours is the same as mine, you should have a large red plastic flag switch adjacent to the driving position. My switch is off when pointing to 3 o'clock and on when pointing at 6 o'clock. However, the red plastic flag is removable for total isolation/security, which just leaves a short shaft protruding. If this is not easily spotted, the flag may have been placed in the glovebox or similar? I think you may be operating one of the rocker switches on the control panel which you press and hold to read one of the gauges e.g. battery level or water tank level i.e. they don't actually turn any power on.
Hope this helps.
Regards
Dave
Hi Dave. We've got a right-hand drive so my red switch is above the wheel arch, in front of the passenger seat. Switching that off/on doesn't seem to make any difference - hence the desperate post. Am I right in thinking that it really is only this switch that should allow us to run from the battery?
Thanks for the help, it's appreciated.

The 12v system should work whether you are on mains or not. Mains is mains 12v is 12v and never the twain shall meet unless through a transformer. The mains power will only effect the 12v system via the transformer in order to charge the batteries. As you say the battery seems to be in good order this may indicate a probem with the fuses to the services (12v bits and bobs) on the output side of the transformer. You can visibly check the fuses easily enough, better still buy a cheap multimeter and use this to test the voltage. You would not normally have a switch to "switch over" to 12v as that supply is normally always on unless isolated as Dave suggests. However, some vans, my own included(Hymer 740) have a very innocuous looking switch on or near the main panel which turns off all the internal 12v power. Make sure this is not the switch you are turning "on" ie. turning the 12v power off.
Hope this is useful good luck

flicking the switch that should switch us from the mains electricity to running off the 12v battery circuit doesn't seem to have any affect whatsoever
First of all, welcome and I hope we can help.
We have an H reg Hymer and I don't know what switch you mean !!
Where is it ? What does it look like? What do you mean when you say it has no effect - ie what effect are you looking for?
Do your lights and water pump operate ok? They are 12 volt and will work whether on 240 hookup or not.
The only things likely to come on on 240v hookup is your battery charger and fridge.
For example the only switch in our van which has a 240/12 volt setting is on the fridge, the charger is always switched on so that hooking up brings it on line.
Fill in the details and someone will be able to guide you.
Thank you for the welcome and offer of help. The switch I mean is in front of the passenger seat (we've got a right hand drive) - with the red flag on it that Dave mentioned in his post.
If we attach to electric hook-up, the internal lights work. If we're not attached to hook-up, what we do we need to do to get some kind of power for lighting? I understand the fridge and cooker running off the autogas, but isn't there meant to be some kind of battery power for those trips when electric hook-up isn't available?
(Golly, I feel thick!)

I have a PDF of the original handbooks for these models (ours is a B544 from 1988 but has the whole range.). PM me if you need it although I get the feeling we're all talking to ourselves at the moment! No sign of yer man since his first post.
Proves we're so helpful here we can't stop!!!
As far as I know there isn't such a switch per se. If you have 240v plugged in it charges 12 volt batteries. If you haven't it doesn't and your 240v sockets (obviously) don't work.
Earth to TopBhoy?.......crackle.......
Hello? Is that Ground Control?

i have the mercedes s660 f-reg . on the 410 chassis .
i think you had the same probem ,s i had , i think by now i know of every part you can think of electrical , and other wise !! how long has the hymer been here ? sounds stupid i know .on your way in to the camper check above your head over the door ! no cable.s good ! next tell me or send me pictures of how your batteries are kooked up . as this is where the problem lies . garanteed, mine was all over the place as people do change things to suit them selves , the brown oblong box is the fuse box only for the camper lighting this is below the red switch . these supply through the isolation switch . check your fuse,s 16 should be the biggest 8 lowest . blue =live brown=neutral .under the seats bench seat you should find a silver box , this is your 12v, supply and plugged in to a socket mains .this take,s over when hooked up to the 240, house electric . this converts to the 12v supply of all 12v electrical in the camper .
the electric feed is by battery when the engine is running or switched on , you should only need gas when you are with out electrical 240 . and when idle . what model is your hymer !!
let me know , and i will help .
by the way leave the red switch in the on position i use this only when i lay the camper for big rest,s . you did not say whether you have 1 or 2 batteries ? .
all the best , denton.
