Installing Battery Master

[Peter and Sue]

Hi, I would appreciate a little guidance to ensure I'm not about to do something daft with our van's 12v electrics.
We have a Burstner Ixeo Time with a factory fitted solar panel. It also now has a Strikeback alarm fitted by @eddievanbitz and the folks in deepest Somerset.
The solar panel charges the leisure battery however the alarm takes a small current from the vehicle battery.
In order to avoid a non-starting motorhome after a long period parked-up without EHU I bought a Battery Master from Vanbitz at the NEC last week in the expectation that the solar panel would then effectively be topping-up both batteries (when the voltage on the vehicle battery drops below that of the leisure battery).
So - assuming the logic is solid so far - I now need to fit the thing. The Vanbitz people said I could call them up for advice when fitting but though I'd try here first if it really is a simple as I'm hoping!
Under the passenger seat sits a Schaudt Electrobloc EBL99. On the back of the block are three terminals labeled Starter battery positive, Living Area battery positive and Earth.
It seems to me that this is an ideal place to connect the three wires of the Battery Master or am I missing something obvious here?
I'd expect to disconnect both batteries before trying to connect anything but would welcome any suitable words of wisdom.

Many Thanks,
Peter&Sue

this is how vanbitz wired a Battery master into my EBL119

Usual way of doing it is to connect to the block marked Solar, output from the solar regulator to habitaion battery connection, Negative from regulator to negative & the output from the battery master to the starter battery connection.

When I fitted ours to a CBE control system we had as you say +ve starter battery +ve habitation batteries and -ve terminals all next to each other so all I did was switch off the control panel make the three connections and turn it back on.

Ask Eddie! He told me where to do it on my van and told the colour and size of each wire to connect to what!

Which is where our similar device has lived for some years now.

Not everything has to be difficult.

Well thanks to all for the encouragement - I connected the Battery Master as planned and after a few weeks testing it appears to be doing it's job very well!
The only hiccup that almost caught me out was the fact that the existing connections on the back of the Electrobloc are colour coded red/brown/black but switched when compared to the colour coding on the Battery Master - wiring it up by matching up the colours would not have worked! By reading the instructions and the symbols on the Electrobloc (ignoring the colours) I believe it's now wired up correctly and operating correctly. Lesson as usual - RTFM (twice).

Is your Battery Master now showing that red light?

Nice innit.

 

[Peter and Sue]

Nice indeed - I believe the light is working as it should, red when the vehicle battery is getting a trickle feed from the leisure battery, green when they both are at the same voltage.

Regards,
Peter&Sue

Please tell me that brown wire isn't twisted and taped to the larger red wire !!!!!

I didn't think twice about it as I'm not an auto electrician, but I peeled back the tape and it appears to be.
Is it OK or a problem?
Maybe @eddievanbitz can respond?

What's wrong with soldering a small brown wire to a big red wire?

It only trickle charges at one amp

It will be now it's not insulated!

I'd re-insulate that connection if I were you

I did so immediately after taking the photo so all good!

All fitted and working - nice easy job. Thanks for the help!
