Hymer habitation electrics

[Jugster]

Hi
Just returned from France. Broke down 1.5 hours from Calais on return trip

My van was repatriated to the uk for repair. The problem was a failed clutch. When we left the van in France everything worked as it should. ( except the clutch lol ) On collecting the van in the UK, none of the habitation electrics work? No panel, no lights, no step or outside light?
Any ideas please and where do I start? Van now plugged into mains as I suspect the Hab batteries may be flat? If only it was that simple. I will check tomorrow after they have been charging tonight. Failing that I will check the main fuse by the batteries. Any other help would be much appreciated.
Thanks

Have they switched off the Electrobloc ?
&/or switched off the EHU consumer unit ?
&/or switched off the hab control panel ?

I'd start by looking at switches before before looking at fuses.

 

[Jugster]

Ok, thanks. Will start searching tomorrow. If they have switched off the electrobloc etc, I’m wondering why would they do that? It was transported back on a big flatbed recovery truck. Clutch all fixed now, but I just need to sort out the hab electrics

On the hymer Electroblock
AUS = OFF
AN = ON
(It will be a little black switch in the middle)

On the consumer unit, which will be located on the inside of the EHU socket,
All the switches should be in the 'up' position

Check the hab battery is still connected. A good garage would disconnect it (and the starter battery) to stop anything being live whilst working in the engine bay whilst replacing the clutch. May get overlooked after completing what otherwise is a regular clutch repair job.

They could slso have pulled out the main fuse. Ours are close to the electroblok. May have isolated it to comply with their transit insurance policy. Our dealer had this fuse out when we first saw our Hymer in the showroom.
Hope that you get sorted.

Hi all
An update. Today I checked the 50 amp fuse for the elecrobloc, this was burnt, I have replaced the fuse. Still no 12 volts? Am I correct in thinking without the 50 amp fuse in place then the leisure batteries will not charge even though on ehu? Sorry to be dim, but electrics not my strongpoint! If this is the case it explains why the display is not working and the 12 v not working yet, as I believe the leisure batteries are flat. Now that I have replaced the fuse and plugged into the ehu, Im hoping the batteries will charge back up? After replacing the fuse I did briefly get a message on the display saying charge batteries, but it then faded as I had not turned on the ehu then. I will check again in a few hours time and see if it has improved.
Thanks for all your support, I will keep you updated.
What do you think caused the 50 amp fuse to blow? If my engine battery had gone dead during the 2 weeks it was parked up, do you think they would have jump started it with a power pack? Could this have caused a spike?
Thanks.

There’s a 50A fuse between the starter battery and the EBL. There is another 50A fuse between the EBL and the leisure battery. Have you checked both of them?

 

[Jugster]

Not checked the battery fuse in the cab but changed the one by the ebl. Thought the engine battery fuse was just for the cab side? What do I know! I’m out of my depth here

 

[StillGoing]

Check the leisure battery voltage (with no solar or ehu). Check the internal battery charger (Internes Lademodul) fuse on the front on the EBL. Check the switch Batterie-Trennschalter on the front of the EBL is switched to Batterie Ein.

What does the 50 amp fuse by the starter battery do? The engine starts, runs and drives perfectly now?

The 50 amp fuse by the starter battery feeds the split charge relay inside the EBL, shouldn't have any effect on the hab electrics.

Sounds like apart from the blown fuse the hab battery is really flat so probably knackered.
With it on charge check to make sure it is not getting hot.

Thank you, I’ll check these fuses tomorrow. Thanks for the very clear translation, I should of checked with google translate lol

Ok managed to check these this afternoon. Firstly the new 50 amp fuse was burnt again? Checked engine 50amp fuse, all ok. Replaced ebl 50fuse with new. Checked Internes lademodul fuse, all ok. Check both hab batteries voltage, showing 6.8? Switched on ehu and checked to see if battery charging, now showing 8.6, so it looks like they are now getting charged? I am at a loss for why the new fuse blew?
Going to leave it til tomorrow now and check again to see if the fuse has blown again. Could be that I’ll need to replace the hab batteries , any thoughts please? Other than that I think it might be a trip to Apuljack engineering!
Thanks all.

 

[Lenny HB]

Fuse probably blew due to the state of the batteries, I wouldn't try charging them just bin them and get some new ones. The last thing you want is a battery exploding.
You will get 10 - 15 quid each for then at the scrappie.

If I replace them with new, is there a procedure to follow for fitting them please?

No, just make sure everything is turned off and leave the fuses out till complete.

Might be a good time to think of a lithium upgrade if you are keeping the van. Just one lithium will be the price of 2 decent lead acid for the same power.

 

[Jugster]

Got a Hymer with electroblock so I believe lithium not an Option

It is, I have the same and have lithium.

Do you have a B2B charger? If so, you just need to change the EBL to gel and you are good to go.

Has the hab battery been switched off? Mine is under the drivers seat

It is an option.
But not just a simple swap.

There are some things that need to be changed, but ask for EXACTLY what needs to be done on here.

A flat battery will take 24-36hrs to fully recharge, so keep an eye on the one you have got.
It it heats up, swells or starts to smell of rotten eggs, remove it it from vehicle immediately.
It is not sleeping, it is no more, it has ceased to be, it is bereft of life .....

Even if it does recharge normally, there is a good chance it's on it's last legs nailed to the perch, and will need replacing soon.

Lithium is the way to go, twice the power, twice the cost, half the weight and it will last the life of the van.
So it only makes sense if you are pining for the fjords and intend on keeping the van for a few more years.

Lots of folks have Hymer vans and have switched to lithium, check out the Hymer Owners Group on Facebook. I am just waiting for our AGMs to fail before we switch to lithium on our Hymer.

One by the starter battery is for the ebl and the 20 amp runs the step also the 50amp by the leisure battery disconnect these before charging batteries with a battery charger as it will spike the ebl unit it happened to me and cost me a repair

Some EBLs do have a lithium setting eg EBL400. Battery type can be changed via the Schaudt control panel eg LT460

Incorrect the 50 amp fuse by the starter battery feeds the split charge relay in the. EBL the 20 amp fuse is the feed to the fridge when the engine is running, it also carries the trickle chard to the starter battery from the EBL.

 

[Lenny HB]

Reguarding using the EBL to charge Lithium is OK occassionly on the setting but not recommended it you often use EHU. You should only have an absorbtion phase of one to two hours not the 16 hours an EBL does.

Hi all
Update again!
Decided against trying to charge the batteries through the ebl so switched off ehu.
Both batteries Reading 6.8 volts so obviously knackered. I am at a loss as to why they ended up in this state cos over the 7 weeks away they were showing good voltage on the control panel, but I was on ehu most nights.
I’ve decided to replace both varta leisure batteries with like for like, but I am waiting for a call back from Apuljack to discuss the way forward! I don’t want to fit new batteries until I know that the ebl is all ok. So for now I’ve pulled the 50 amp fuse out. Hope that makes sense. Thanks for all your advice, such a great resource. Looks like a trip to Apuljack shortly. I will let you know the outcome when it’s sorted.

 

[Lenny HB]

You could just connect any battery up to check the chargers working.

 

[Jugster]

I believe charger is working as when on ehu briefly I used a meter and both batteries Reading 8.6 v, so switched off ehu quickly before fuse blew again! If both batteries are knackered would this then blow the 50amp fuse when the engine was running? Or could I have a discharged engine battery also? Never thought to check that one. Will put meter on tomorrow! Too cold and too much snow today!
