Anyone know how these work or have a wiring diagram for one ?

I've got a leisure battery in my van but i'm not sure it's all working properly

I've a dash switch which the previous owner told me did nothing, on further inspection it operates the solenoid that both batteries are connected to

But no matter what position it's in the 2nd fusebox draws voltage from the main battery

when i fitted my 2 leisure batteries,i bought an intelligent relay off ebay.
It doesnt need to be connected to the alternator at all.
You take a fairly heavy duty cable from your main battery (starter battery,put an inline fuse in it for safety)to the relay,the second connection is for a earth cable and the third then takes a cable to your leisure battery..simples
It works on sensing when your ignition is switched on and will charge both batteries but only uses the leisure battery when the ignition is switched off
I bought this one because i needed a big ampage to run my hydraulics but there are cheaper ones on ebay,just depends on what sort of stuff you'll be using

Ah coolio, i might rip out my system then and re do it with one of those

I gotta do this aswell

............ only want it for the fridge, so my beer's chilled for the shows !! but if its as easy as Rich says, then it's a winner !!

I just want to be able to run a cooler and have a socket for phones dvd players and the like

I've got a split charge relay which I found on ebay for a fiver. So far it's fucked up 1 leisure battery and one normal battery.... maybe I wired it up wrong

Dickie, do you remember the basic wiring for your relay? we were trying to fit Toby's at the weekend (similar to yours) but the instructions are gash

yes mate,well almost
2 main connections on the relay (the bigger terminal sizes) went to main battery and leisure battery and the smaller terminal was just for a body earth.
Not sure which big terminals went to which battery but that was all that needed wiring

Great thanks mate!

The box has 11 terminals but we could only figure out the two battery connections and the earth as you describe... I was thinking we were missing something but it sounds like it's all ok with just the 3 connections if that's what you have

I've got a basic diagram if anyone wants it, won't let me upload it here sadly

keep hold of that diagram for me please mate.

i'll get it off you at a club meet or maybe at busfreeze if we see ya there.

cheers

scan it and up load it as a pic . or even take a pic of it

No worries, i'll email it if you need it any quicker

Here ya go, where there's a will there's a way

I've drawn it myself after working out what's on my van, mine differs slightly as mine manually switches the leisure battery in or out
