Bailey Approach Advance 665 - Something is draining my battery

[MerlinUK]

Hi

I have a 2018 Bailey Approach Advance 665. I have an external hook up point at my house so it is easy to top up the batteries. However, I am reluctant to leave it on permanent hook up as I worry about the effect it will have on the battery and charger.

When I take it off charge the battery’s voltage is usually around the 13v mark. A week later it is around 12.5v to 12.6v. I was advised to not allow the charge to go down below 12.4v so I invariably end up putting it back on charge again.

When not in use I always switch the master off. There is nothing other than original items connected to the battery.

Looking at the fuse box I assume the following are running of 12v.

Lights 1
Lights 2
Aux Sockets
Pump – Toilet
Current Monitor
Water Heater
Level Sensor
Hob Ignition
Spare
Fridge Ignition
Van Batt R
Fridge

I wonder is any of these are NOT switched off when the master switch is OFF.

I’d assumed the master switch pretty much switched everything off. When the master is off the control panel shows a current draw of 0.0A.

Any ideas what is draining the battery?

12,6 is a fully charged battery you need to leave the battery an hour after you remove the charger to get a true reading

Unfortunately a few days later it is below 12.4v :-(

TV aerial amplifier?

I'm assuming you mean the domestic battery - not the engine

I found a halogen bulb in one of the wardrobe wasn’t going out when the door was closed.

Yes, the habitation battery. I'll check the TV aerial amplifier.

There are no lights in our wardrobe. But Thanks.
