Elektroblock EBL213

[Hymer Phil]

I have a 2016 Hymer 634SL. Just recently I had one of the two leisure battery fail. After replacing both batteries, I had no electrics to the main control panel. After a lot of research and negativity from the dealership. I found the blue control unit (EBL213) was the cause. However I removed the security screws and found a relay had tripped off, this was simply reset and everything worked fine. A lot cheaper than the £2k + the dealer wanted for a new box.
Hope this is useful to anyone who encounter a similar problem.

These things are a junction box, some fuses, a charger and a couple of relays. Yet they're ridiculously expensive.

Mine has an over complex data bus that control satellite modules... that do things like turn the pump on and off. Why?

Where is the relay?

I agree, this things are very expensive for what they do, and keeping it simple should be better.
Nevertheless I find the CI-bus (which is the standard used by the main motorhome manufacturers out there) an interesting evolution to control everything in the motorhome through the panel, using a lot less wires.

I've got separate modules for lights, pump, tank levels, the fridge, tank heater, and one that interfaces with the Trauma heating. They're daisy chained together. And everything is on soft fuses. It's all very clever, but it feels like the early days of canbus when the standard wasn't very standard, wasn't very robust, and was a pain to diagnose when things went wrong.

I've had my panel loose it's programming. Which meant it wouldn't recognise the pump module, so wouldn't let me run water. It was £450 to replace, thankfully covered by the warranty.

What was wrong with using a switch to turn lights, pumps, etc on or off.

I see your system is a level further up more complicated.

I see your system is a level further up more complicated.

Everything is hanging off a couple of those STDbus connectors that Hymer Phil 's unit has. But it looks like he's also got the option to connect a lot of stuff that traditional way, straight to the block. My block looks simpler because I've not got the legacy connectors.

Instead I have many of these things buried around the van.

If only it was lithium compatible.

Oops, I see...
There's a module for each thing around the van it's a mix between traditional connections and bus. Didn't know about that. There's a red diagnostic led on there?
