EBL 99 - internal fuses? (1 Viewer)

[Dave and Ginny]

Hi all

Not mine but trying to help friend with Hymer 680 2004.

EBL has died and he is looking for internal fuse that I understood all Elektroblocks have? He has it out and opened up but cannot see anything.

Any help appreciated.

Dave

Sorry Dave, I don't know where the internal fuse is, thought I was a glass fuse the back of the charging module, but have never looked inside..

What has died.. I presume it's not charging on EHU ?

mine 'died' recently, not charging on EHU and a relay was chattering loudly .. I had it repaired at Apuljack Engineering.. fast turnaround , less than a week. cost £208 inc vat p&p

The wiring diagram in this manual might help

I think most of the fuses are on the outside but there are others on this site that know more about this than I do.

Don’t know about charging Jim, but the guy is in Spain, not on EHU, went to bed all ok but in the morning no 12 volt. All fuses checked and power going in. He’s waiting for a reply from Apuljack, but being hundreds of miles away is less than ideal...

ok.. don't think it's the internal fuse.. it's on the output of the 240v charging module

If he is sure there is 12v going in, has he tried exercising the battery ON/Off rocker switch on the EBL next to the fuses ? switch off and on several times

Thanks though, it’s looking like there may not be any fuses other than those on the outside. But, an internal, maybe as low as 2amp, small glass type fuse has been mentioned on another forum before, supposedly an internal protection fuse which kinda makes sense. But with the case open nothing can be seen.

Good point...I remember they can be trouble

I think there is a fuse within the internal charging module LAS1218, that is part of the EBL 99. I have never looked inside mine. I think a bit more information about what has failed or what it is not doing might help diagnosis.
I had mine checked and repaired by Schaudt a few years ago but that was a faulty input socket and front panel switch, not a total failure. The cost, including carriage, was very reasonable. About £150 as I recall.

Thanks Philip. The 12 volt output just failed overnight it seems, no more details than that I’m afraid. All the obvious fuses have been checked and power is entering EBL. No sound of the relay kicking in when turning 12 volt on at main panel.

Here’s some pics of the internals, just in case anyone can spot anything!

 

[JeanLuc]

That sounds to me as though one of the 12v internal relays has failed, or possibly the front panel switch if that has been activated recently. There are two switch-on relays: one is activated by the front panel switch; the other by the control panel switch. Does the step still work? If so, then it is the second relay, activated by the control panel switch, that I would suspect.

No, step is not working either.

I would contact Udo Lang at Schaudt (he speaks English) and ask for advice. He may be able to suggest a local agent or possibly a return to them option.

Don't know if this will help, its a pdf with the wiring diagram on page 13.

 

[bigtwin]

Does he know the state of the batteries?

If they are too low, the control panel sends a signal to the charger to switch off.

It may be a battery issue rather than a charger issue.

As they’re in touch with Apuljack Engineering, I’m sure that they’ll assist with a diagnosis.

Thanks for all the input to everyone. It turns out that @scotjimland was right and the suggestion to get physical with the battery rocker switch has kicked it into going again.

Jim, you are really missed somewhere you know

 

[JeanLuc]

Glad it is sorted out. I would suggest to your friend that he has the EBL serviced when time permits and the switch replaced. The rocker switch is known to be a weak point. In fact AandN caravan services recommend not using it at all, although that may not be possible given the need to change batteries from time to time, or when carrying out electrical work.
If the switch fails again, it might not be possible to restore it with ‘vigorous action’.

This might not be the answer, but I had similar problem a few weeks ago, long story short, squirt WD40 into the main switch on the front of the ebl, then operates few times, switches ten to go dry occasionally, sorted mine, good luck

I think that they may have sorted it some 18 months ago.

[bigalw35]

I appreciate that fault may have been sort of sorted some time back, but if your not careful the internals of the switch could be damaged due to friction, the WD40 releases and lubricates the internals, worth doing it to all your switches occasionally

 

[Vipar]

I know nothing about electrics so I give everything a wiggle in case it’s a dry joint if there is no difference then I panic?

A dry joint is one thing, but normally a permanent cure can only be affected by soldering, but the likes of switches require freeing and lubricating

We had a problem with our voltage regulator and had to switch off our 12v supply. When we went to switch it on again, it wouldn't come on again for 12v supply using the rocker switch so we had it looked at while in Portugal. It turned out to be an internal relay in the EBL99 which got stuck in the off position. This was reset by Tommy at Camperserve and has been fine ever since.

Hi I have just switched on my 12v supply and it’s clicking continuously when I pull out the 10 amp fuse for the tv the clicking stops could someone help.

I had a similar problem with ours (2001-680) stripped it down, could find a fuse ?? All it needed was a squirt of WD40 in the switch, it’s now perfect

So if I lift out the unit take the top off and spray wd40 it should stop the relay from constantly clicking.

 

[bigalw35]

No, just spray the switch from the outside

I did the same ,works great now
