EBL 208 issues

[Tomaj]

Hi all,

This is my first post here
I am coming from Slovenia and just bought used 2018 Adria twin plus 640.
It has only 60.000km and looks and drives like new!

Well, with one small exception...
When I got it, the 12V power supply works fine in the living area. Few days later tle living area battery died. It was good only for a minute or two.

So I decided to buy some lithium cells, BMS, DC-DC charger, inverter and all other stuff. I am using Votronic 1212-30 charging converter.
I hook everything up according to wiring diagram on Votronic page.

There is power in living area, both batteries are charging...so basically all fine.

But the problem is that it looks like something is wrong with the EBL 208. It is not up to the task. It handles only the the LED lights in the living area. If I try to slide out the step, everything dies. Same happens with the electric sliding door, 12V power outlets.
But strangly, 12V refrigerator works fine.

I have checked all connections, fuses, wirings...Power sliding door draw max 4A, same is with the step. But the voltage on a relay for the step drops down to 0V.
Same happens also when it is connected to 230V power supply.

Has anyone maybe had simmilar issues?

Thank you for your answers

Welcome to Fun, sorry i cant help you but at least this will bump it to the
top of the page.
Good luck and i hope you get it sorted.

Do you have a manual? If not this link may help.

Have you checked the external fuses near the batteries as well as the ones on the EBL.

Welcome and a bump to get u back on the first page.
If it were me I would disconnect all the new stuff you have put in and go back to the ebl and new battery.(make sure its fully charged off the vehicle before fitting)
That way u should get back to how it was all working before. If not working then perhaps the ebl has gone faulty or fuses blown.
If all good add one piece of new kit at a time and test everything before adding more.

Hi welcome,
Are the connections all good? I recently had a situation where all low powered 12v stuff worked fine but the moment I asked for more than 2 amps it would not cope.
Mine was a split connector on the negative of the leisure battery, which when I initially checked it seemed good, but I guess it could be a poor connection on any of the main 12v leads or earth's.

Good luck in finding it.

Going out on a limb I will suggest this is a bad connection on the power side. Just connected enough to work but as soon as you put a load on, the connection fails

That makes sense and makes me wonder if the new lithium battery has the same sized posts as the one it has replaced. I got a bad connection once when I hadn’t noticed the post and clamp were not matched properly.

The main leisure battery connections are some of the 24-way spade connectors on the front. 1 and 2 are the leisure battery positive, 5, 6 and 21 are the leisure battery negative. I would try to find a way to check the voltage at those points, with a meter ideally, while you are trying to operate the step.

If that voltage stays up over 12 volts, but the step works as you said (ie the voltage drops and the step stops) then the problem might be inside the EBL. If that voltage drops also, then the problem is external to the EBL, somewhere on the leisure battery supply wiring.
