Leisure battery not charging.

[Keith E]

Good evening everyone, I hope you are well
My leisure battery isn't charging.
We've a 2012 Bailey Approach 745se which we purchased in November last year.
Other than use for one night, it's been in storage since we bought it.
I brought it home on Thursday last week and the leisure battery seems to be flat.
I can't even get the master panel to illuminate unless I use the HU, which has been connected constantly for the last five days.
I think there's actually an open circuit somewhere rather than the battery being flat but all the wiring appears to be intact.
The leisure battery was functioning when we took delivery of the MH.

It has the devices shown in the attached pictures but I have no idea how to operate them, there are no instructions.

Is there anyone familiar with this kit who may have a clue where my problem lies please?
We're due to take it away on Wednesday and I've been working all weekend so haven't had a chance to contact the stealer.
I've checked the fuses that I can find, not those that aren't obviously related to battery charging.
The leads from the battery disappear into the mains unit and there's no online fuse on the battery leads.

Thank you in advance.

U need to check the state of the hab battery (off the vehicle if I was doing it) or at least disconnected from the vehicle. First remove the + connector from the solar panel to the solar controller before disconnecting the battery.
Check the battery readings with a muiltimeter if it's less than 12v it might of had it. Charge it with an independent charger set for the battery type if it's a good charger it might be able to recover a near dead battery. Leave it for a couple of hours disconnected after its charged and test voltage 12.7 or above good down at 12 then new battery.
Now you can worry about the solar side. Make sure a battery is connected before reconnecting the + solar panel wire.

Thanks for the quick reply.
I've just sorted it.
Hab battery was 7.2 v so I swapped it for a battery that I knew was good but it still didn't work without the EHU
The leads to the battery were open circuit.
I had a rake around inside the van, under the seats and discovered that what I'd thought was a cable clip, was actually a fuse holder poking into the battery box.
The actual fuse is hidden behind the EHU plug.
New fuse and Bob's your aunty.
The problems that look complicated usually have the simplest solutions.

I'm not going to worry about how to operate the solar connections just yet.
I'll wait until I have more time, find out who's manufactured what and try to find some operating destructions.

You need to be reading the solar output amps (centre grid)- not volts at the battery --- to see what amps you are getting from it/them
