    Just finished running an additional cable to the EBL99 and fitted two new batteries (having convinced myself that the previous ones were on their way out).
    I am confident that the new cabling has been done correctly and I am confident that I have installed 2 x 90 Ah Varta batteries correctly. I have also taken the opportunity to fit a fuse in the +ve feed from the solar panel into the LR1218 regulator. This is not to protect anything - merely to allow me to isolate the solar panel for work on the batteries (the regulator is fused at the EBL in any case). At this point, there is no fuse in the isolating holder and the solar panel is not supplying power.
    The EBL has been shut down for about a week whilst I have been carrying out the work. About an hour ago I finished everything, switched on the main switch on the EBL -NOTHING! Not even the sound of the main relay switching in. I have tried working the switch a few times; resetting the 12V panel switch; plugging in to EHU (the charging routine works as the battery voltage goes up to over 14V).
    I know there is 12V to the EBL from the new batteries as I can measure 12.7V at the rear EBL terminals (same as the rest voltage of the new batteries).
    I am completely flumoxed. I had to move the EBL forward and up in order to run the new cable but I was careful - no sharp knocks. I guess it's a call to Udo Lang at Schaudt in the morning unless a Funster can come up with the answer (which I hope is not a new EBL!).

    Phillip does it have a battery cut off switch and if so is it off? I'm thinking it does in distant memory.

    I'll have a look at the EBL99 schematic in the morning to see if there's a possible fuse gone for you. PM me in the morning to remind me as tomorrow is a very busy day for me.

    Yes, on the front panel of the EBL and it is on. Some deeper problem I'm afraid.

    Thanks Dave - I have a schematic but I'm not confident enough to read it completely to know what goes on inside the box so your advice would be gratefully received. It is an EBL99F but I think the basic layout is the same for the 99 series.

    I had a strange problem with my ebl that turned out to be a loose spade connection on the battery feed.
    All checked out with multi meter but it wasn't until disconnected and reconnected the spades that I found it.
    I had the battery out and had been moving things around.

    Are saying the control panel is dead ? No mains LED and no 12V LED ? Anything on the meters ?

    Thanks to SandJ for the link, I've looked over the schematic and there are no internal fuses identified. First check I'd make is have you got +12V at pin 3 of the solar input (3 pin socket on front panel, pin 3 is the bottom one) with a good fuse in the solar slot? If yes then it would appear to be an internal issue in the EBL, if no then recheck the main input connections at the rear of the EBL.

    Dave just incase the Ebl99f has a fuse you may find this helps on iPad and doesn't seem to work right
    You may already be aware of this though

    My electroblock stopped charging and there was a tiny old fashioned fuse blown underneath. @JockandRita told me about it and produced a spare to save the day (y)

    The EBL is charging Jim, it just won't switch on power to any equipment, at least that's how I read JL's initial post on this.

    Which means metering the 10 way control panel connector Pins 9 (on) and 12 (off) to see if any change volts volts when 12v power switch is switched off on.

    And what was the mysterious extra cable doing ?

    HI JL,
    Just been reading thru' your thread,just in case your EBL might have expired this may be of some help; A&N Caravan Services, go to their new website and click on Schaudt Electroblock you should find alot of useful tips/information there.If you contact them I believe the person you want to speak to is Alan he should be able to help you with any EBL problems,I'm also told that they have a very quick turnaround on EBL repairs and apparently they are very competitive on repairs,so maybe all is not lost,be sure to check out the advice section under Schaudt,sorry I can't be of more help,hope this helps though.gwyntaxi.

    Well - now I'm totally confused.

    As I mentioned before, I was confident that all the work I had done was OK. I knew too, that 12V power from the batteries was getting to the back of the EBL - but the habitation 12V would not switch on. The EBL has two internal relays. Relay 1 is switched by the main switch on the front panel. This activates the system and supplies power to the step, doorway light and frost protection valve for the Truma. Relay 2 is switched by the 12V power switch in the control panel above the door. My problem was that Relay 1 would not switch on and so Relay 2 would not switch on the internal lights, pump, sockets etc.

    About 2 hours after my last post, I went back to the Hymer to lock it up for the night and decided to give it one more try. On switching on the main switch on the front panel, I thought I heard a gentle click - tried it again with the same result. So I went to the hab door and switched on the 12V switch in the control panel - all the systems came on!

    I can only assume that there is some form of capacitor in the EBL that has to become charged before Relay 1 can be activated and that leaving the system connected to the new batteries for some time allowed this to happen. I shall now send an email to Udo at Schaudt to confirm if this is the case, or whether I have just been lucky and some fault remains.
    For now, I seem to have got a result. (y)

    We're having trouble with our Ebl99 too.
    We were on hook up and the safety cut out switch tripped, reset it and the 240v indicator light isn't lit and the batteries aren't charging. The 240 sockets work ok and the 12v system seems ok.
    There is 240v getting to the Ebl and we do have a overload protector fitted.
    Batteries seem to charge when running engine.
    There is also a LAS 1218 under the passenger seat with 240v to it but nowt coming out(this seems to go to block 7 auxilary charger on the Ebl) I suspect this hasn't worked for some time.
    So my assumption is that the charger inside the Ebl has gone, or is there something i've missed?

    Merc S820 circa 2003 Batteries 3x 80Ah Exide gels, have checked fuses on front of Ebl and LAS 1218 (20A) both fine.

    Our ebl99 charger self destructed, not uncommon, you can post it to Germany for a fix.

    In your set-up, the LAS1218 is installed as an auxilliary charger so that a large battery bank does not overload the EBL99 (or make it painfully slow to recharge the bank). I guess, since it's a S820 that you have three leisure batteries. The LAS1218 can be connected in two ways but from your description, it is used as a boost charger to the EBL in which case its output simply goes into block 7 and from there direct to the batteries. To all intents and purposes it becomes an integrated unit with the EBL99 which already has one LAS1218 module within it.
    Have you any idea why the 230V incoming switch tripped? Was it a supply voltage problem or perhaps did a failure of the EBL cause it? There is a fuse within the LAS1218 module inside the EBL and this may have gone. That would not explain why the external LAS1218 is not outputting any 12V though, unless the fuse in that has gone too. Are you confident that the overload protector is not at fault? If it is a Schaudt OVP1, persumably both the EBL99 and the external LAS1218 are supplied by it. I would suggest taking it out of the line and feeding the kettle leads directly into the two units to see if the overload protector is playing up. The 230V sockets in the van are on a separate circuit to the EBL/LAS1218 supply so will not be affected.
    If this does not yield any results, I think you might need to consult an expert. Udo Lang at Schaudt is very helpful (see his email address in my earlier post) but he is on holiday until 13 April. I have no idea how to replace the internal 230V fuse in the EBL if this is the problem.

    Have had a few problems on our 584 recently, thought it was battery problem but after changing still had a problem. Had email contact with Udo & he suggested the switch on the elb has a habit of corroding. I rocked the switch on & off a few times & got back to full function.
    Udo suggested a good soak with switch cleaner & if that failed a new switch. Although seeming a simple repair apparently the switch is soldered into the internal circuit board. He quoted 50€ to fix once unit in Germany. Give the switch cleaner a go JL . Contact cleaner at Tool Station about £3.

    PS. Udo did suggest that it wasn't a good idea to leave the van on EHU for too long without a rest for around 48 hrs.
