The battery on my van goes flat after fully charging it hooked up.There does'nt seem to be any appliance on (boiler etc)to drain it.I have changed the battery for a brand new one to see if it makes any difference but the same thing happens.How can i find whats draining my battery,many thanks.

Make sure you set the car/van switch to the middle switch setting which is off , but not normally labeled .
If it's not set to off, power is sent to the relays in the caravan and these will drain the battery over time .

Do you have a charge controller between the solar panel and the battery ? i imagine you have . 
Charge controllers can be damaged if they are disconnected from the battery and not the solar panel first , i would use a multi-meter to check the output from the charge controller .

Many thanks wizard(just spent 1/2 an hour on your website)my solar panel is one of the latest models plugs into the grey lead.It has controller fitted as standard to the panel.why would this cause a problem on my drive after fully charging battery via hook up.Then unhooking van the battery just goes flat?

Double check a few things first.

Is it fitted with a mover, but it's left switched on?

Is there a 12v master switch which isn't switched off?

Are you sure the EHU charger is actually still working, and the battery really is fully charged?

iv just come home from a rally i killed a battery in 1 night, went a way noing somthing was wrong with the water heater but not the lights sat in van for about 2 hours when thay started to dim and the battery level light went to red,so i was messing about with the zig and pulled the fuse out for the lights  and it turned back to amber so the next day i took every light out inside the van checked em and put em back still no joy i couldnt take the awning light down didnt want to break the seal in the bad weather got home and took awning light off and bingo the lights and waterheater all work fine now so there must have been a short there
