Horsebox
Hi all, I thought I’d come here as would have more information on the living side.
I actually have a horsebox rather than a motor home.
ve got a 7.5 ton horsebox, it has a good living with hook up but the water pumpfor the sink and shower and some lights run off the leisure batteries and the rest of the lights and electric sockets off the hook up.
How can I make it so the water pump and other lights run off the hook up too?
Leisure batteries are rubbish anyway plus we regularly stay away for 4/5/6 days at a time seems a better idea to have them run off hook up than replace the leisure batteries!!
At the moment I’m turning the engine on to wash up/shower!
Thanks in advance!

Hola and Welcome. No idea about the horse box. Is there a manual? :welcomesign:

Assuming you don't already have an onboard battery charger, which it seems you don't, You're going to need a 12v power supply capable of supplying up to maybe 20 amps to connect to the 230v hookup electrics then everything connected to the battery needs connecting to the power supply via fuses.
Then bin the batteries.

Hi and thank you.

To be honest I’m clueless I can work everything in the living but wouldn’t have a clue about the electrics!!
The leisure batteries are underneath in a skirt on the left hand side and the hookup and fuses etc on the right hand side half way up the lorry.
I’ve been driving a very basic 3.5 ton with very small living until now but doing the 7.5 ton test over the next few weeks (theory tomorrow )
My dad can do a certain amount in the lorry if I can explain what I need to do!!

a new pair of leisure batteries are about £100 and should last 3-4 years if kept charged in good condition. yet to see a big box with living that doesnt have an onboard charger. new batteries should see you sorted

Yes I had a quick look into leisure battery cost just wasn’t sure if I convert it all to run off hook up as I always get that anyway at a similar cost to new batteries. I’m guessing it’s not as easy as that though.

Maybe there is a charger but it isn't working.
When on hookup the charger will power the 12v stuff regardless of batteries being good or not.
Just replacing the batteries may not financially be a good move if other things need looking at as well.
You really need someone with electrical experience to check it over.

I don’t think there’s even a charger on it, there’s 2 batteries there.
They work for a while after a journey and if the engines running but that’s it.
Will get my dad to have a look at the weekend he’s coming to look at some other stuff on it anyway.
The tap switch is broken so needs replacing and the window seals need some attention and the broken fridge 3 way fridge needs taking out as not working and the electric counter one putting in its place.

Hi, it really depends on if you are prepared to be totally reliant on your mains hookup. Do you never need stuff to work perhaps when en route? in which case the batteries are useful safer bet. But basically you either need as Pappajohn says a good 12v power supply to run everything but only when you have hookup or a charger (which will likely be of smaller rating) to top up the batteries.
Just read your later post. Sounds like the batteries are being charged from the engine but are not holding their charge Knackered is the phrase!.
If you give us a clue where you are, someone will hopefully be able to point you at a reliable electric person.
Best wishes
Mike

the 3 way one may be a simple fix too. sounds like a typical box really with the living neglected between trips out. a little knowledge and some diy skills needed

Thankyou, no only need to use the stuff one we arrive at the shows. Happy to rely totally on hook up, I’d rather spend the money converting it all to hook up than new batteries if it’s similar cost although don’t want to spend hundreds and hundreds converting it over was hoping it was something simple!!

And yes the batteries look knackered by my untrained eye think they’ve been on for a while

I’m Windsor Berkshire my dad has a good electric guy though who he’s used for home and business for 30 years unless a vehicle one would be totally different.
I’d like to avoid using a horsebox person as the minute you put horse towards the equation the price instantly doubles!!

if theres no charger its no suprise the batteries are dead if youve been using them till they fail over several days i would wire a battery charger into the 240 side and get new batteries

Install a wheel linked to an alternator in the horsebox and get the horse to walk inside the wheel to turn it. ;)
