Schaudt EBL 267 issue

[chillidude]

Hi everyone, I’m very new here.
I’ve got my first issue with the electrics in our Fiat Mooveo C7
We have a Schaudt EBL 267 unit next to our leisure battery which before storing the van before winter everything worked.
But checking everything last weekend the electrics won’t turn on using battery power. Everything turns on when the engines running and from electrical hookup.
When you click the rocket button on the control panel above the door you can here the EBL 267 unit click.
Battery is fully charged and is kept topped up with two solar panels at 350w.
Has anyone had this issue or could help?

I’ve also checked all the fuses shown in the photo. All are fine

I’m sure someone who knows your van and system will be along soon but I doubt the solar would have been able to replace any drain if something was left on or there is a small fault. dont want to appear rude but how do you know your battery is fully charged?
It’s normal (in my van) for all 12v to work on hook up or with the engine running as this effectively powers everything via the battery, even if they are empty.
enjoy the journey with your van. Cush

Near the leisure battery there will be a big fuse on the power wire from the leisure battery to the EBL, usually 50A. Also next to it there could be a small 2A fuse for the 'voltage sense' wire. If the 2A fuse has blown, the EBL power won't turn on.

As Cush says, you need to check the battery. Read the voltage with a multimeter on the battery terminals to be sure the battery is charged - the display panel could be misleading.

Thankyou for your replies.
I checked the battery over the terminals with everything unplugged just to make sure.
I’ll check those fuses mentioned. Does the system use the EBL for hookup and engine running?

Does the system use the EBL for hookup and engine running?

Yes. The EBL has a built-in hookup mains charger. There is a relay that connects the alternator/starter battery feed to the leisure battery while the engine is running, so that the alternator can charge both batteries.

There is a point inside the EBL that all these are connected to, plus other things like solar and auxiliary charger. You can measure this point by several methods. For example, the 2-way connector (Bloc 3) Pin 2 goes directly to this point, via the fuse labelled 'Chargeur auxiliaire' which I see is present.

That common point is being supplied by the hookup and alternator charging while on hookup or the engine is running. It looks like the leisure battery power is not reaching that point for some reason. That big fuse by the leisure battery is the first thing to check, assuming the battery voltage checks out OK.

The manual for the EBL267 (English version) is available on the Schaudt website.

Thankyou.
I have my solar panels connected directly to the battery terminals. Is this incorrect?
Also which big fuse are you referring to, so I know I’m looking in the right place.

I mean the solar panel charger is connected directly to the battery.

There should be a 50A fuse somewhere very near the leisure battery. Probably an in-line Maxi blade fuse. And next to it a 2A standard blade fuse for the voltage sensor wire.

Near the starter battery there should also be a 50A fuse, plus a 20A fuse for the fridge 12V element power, and maybe a 2A fuse for the D+ (engine running) signal. But the starter battery fuse seems to be OK, if it wasn't there'd be no power when the engine is running.

The solar power can go directly to the batteries or through the EBL, whatever is most convenient. In the photo there is a pair of wires going to the 3-way connector, normally used for solar input. It goes through the 15A 'Solar' fuse to that common point I mentioned above. I thought that might be your solar input. There's a limit of about 15A on the solar input through the EBL (about 250W of panel), which is enough for many setups, but bigger solar arrays might need to go direct to the batteries.
