Help with electrics needed

Ok thanks.
So I think I've located the split charge relay next to the leisure battery.
Is there any thing else that is likely to be making the battery's act as one?
If not, may just have a go at replacing the relay and see what happens.

You may find that the split charge relay contacts have welded themselves together, connecting both batteries permanently.

As Martin said early.

Tonight I finally sorted it!

I found the split charge relay and there was a mass of not very well connected cables to it.
After a bit of head scratching I decided to disconnect everything so I could work out what was what.
Turns out the relay was fine and at some point, the mains charger had been connected to the relay on both sides therefore, connecting the two batteries together.

The battery's certainly work independently now and I'm hoping this was the cause of the battery's being drained.

The camping lights and stereo I've found run from the starter battery and would like the to run from the leisure battery. I plan to run a feed from the leisure battery but not sure what fuse ratings to use?

Thanks

Also, does anyone know if a current drain of 0.04A when nothing is on is normal?

Thanks again ;0)
