Does that mean the 2nd week of Sep. I'll be sorting out your electrics again? :rofl:

Lol to be honest im still confused by the electrics. The alternator battery saga seems to have been a one off so far as its not done it since. Still only getting 5 or 6amps in to leisure batteries from the alternator but I am getting something so im not sure if relay is working or not.
Solar is definitely working better but not sure if it will be enough in winter or not

So no further forward lol.

Remind me about what's wrong with your EBL. What number EBL is it?

At the minute im unsure if its working as normal or if there's a fault with the internal relay / shunt for the alternator charging of the leisure batteries. I dont seem to get much from it ...last year I was getting almost nothing even if I'd driven several hours.

At the minute when my batteries are about 80% I get around 5 - amps from the charger when engine running.

Seems to work OK on hookup but as i wildcamp mostly I'm reliant on engine charging and solar charging.

Its an ebl 101 18amp model
 
Thats toby been dropped off at the garage to have the cambelt replaced and the clutch master cylinder and brake fuid change done.

Hopefully a goes smoothly ....i always get nervous leaving my van with mechanics ...not sure why

It is a simple relay within the EBL that controls split charging. It's a device that connects the alternator (or more often depending on how it was wired the starter battery) to the leisure battery and has no control over how much charging occurs. I'm trying to explain that it's a simple switch - on when the engine is running and off when it isn't. As such it places the starter and engine batteries in parallel when the engine is running. Because the starter battery is nearer the alternator connected by shorter, thicker, wire it receives the lions share of the alternator output with the remainder available to charge the leisure battery. The alternator outputs around 14.2 volts and as the batteries charge they too rise towards the same voltage. As each battery voltage rises current from the alternator will fall because the rising battery voltage opposes the fixed alternator voltage. If the starter battery charges quickly (which it does because it is nearest the alternator) it will oppose the alternator voltage and little current will flow into it. Even if the less-than-fully-charged leisure battery drags down the voltage seen by the alternator it will have less effect than a less-than-fully-charged starter battery. The upshot is that if the starter battery is at 100% and the leisure battery is at 80% then 5A is good. I certainly wouldn't expect to see more.

As for the 17+volts you saw there is only one component that can raise the voltage to that level - the alternator. It cannot in any way be affected by the EBL or the EBL internal split-charge circuitry. Hope this helps (and doesn't cause more confusion) :Eeek: .

That us the problem though because it clearly does vary ..which is why I get confused.


Lenny HB had told me previously that it should produce more and going by other peoples hymers it seems to be the case

This is what kaasbroodje has going in to his
Screenshot_20200728-101329_Chrome.jpg


And as such while driving his batteries can be back at full capacity within 30 or 40 miles


Whereas mine ....if i use 15ah in a night and my batteries at at 80- 85% the next day ...i would expect that to be replaced within an hour or two driving but it isnt ....in fact I'm lucky if it would rise by 2 or 3% which isnt right.

Now its done that the entire time ive owned the van ....the starter battery, the leisure batteries and the alternator have all been replaced and now so has the dt201

Basically the only thing I've not changed is the ebl

Driving me nuts is an understatement

That looks more like the output of a Battery-to-Battery unit. Or a very low leisure battery.
 
Why not send an email to Udo Lang at Schaudt stating you problem, he is usually helpful.

He has the same system as me no b2b and from what he says his leisures are 180ah fully charged so at 154ah probably about 85% charged

Mine at 85% puts in 5 or 6amp

Yep my problem is trying to explain whats happening in text....i find it easier saying it.

I've been communicating with the guy from a&n caravans regarding the issues but because he wants it done in email rather than a phone conversation I just end up more confused.

OK. With the engine running and the system charging (off EHU) note the charging current you're getting. Then measure the voltages on the terminals on the base of the EBL. There are three terminals. The outers are hab battery and start battery. The middle one is earth. Clip your meter negative to the centre then the meter positive to each of the outers in turn. Note the readings. Then do the same again but with the meter negative lead connected to the outer sleeve of one of the dashboard cig lighter sockets. Again note the readings. Let me know what you find.

OK....I'll have to do thst tomorrow when vans back from garage

But I'm sure Lenny HB did this test last year
 
tonyidle said:
He probably did - it's the first test I'd do. Anyway a repeat won't harm and it'll help me at least see where to go from there.

OK well ill do that tomorrow when I get van back as ill be heading out to work as soon as I get it back today

I had started this thread this morning to see what other hymer owners were getting

www.motorhomefun.co.uk

Who has a hymer b class 2002 -2006 ? Help required.

hey all I'm looking for members who have a hymer b class 2002- 2006 and running the ebl101 and dt201 equipment preferably without any additional battery to battery devices etc. I'd basically like to compare what amps they are getting in to their leisure batteries via their engine running. I...

When I checked it last year I used my DC clamp meter the leisure batteries were initially charging at 25 amps on startup dropping to around 10 amps after a min or two, the batteries were in a good state of charge at the time. We couldn't get it to go wrong. Voltages were OK apart from one of the solar regulators was duff and giving out 18v, we had already disconnected that the day before.
 
Gawd garages don't half like to string things out ....i dropped toby off at 8.30am

I phoned at 14.25 and they said timing belt was done they were just fitting the clutch master cylinder .....wouldn't be long and they would phone when ready ...its now nearly 16.30 ....im meant to start work in 30 minutes

Whit a bloody time to take


I've cut the lawn , weeded the flower beds , wheelbarrowed a 1 tonne bag of mulch all around the garden , weeded the drive , raked the stones on the drive , and pruned 3 bushes aswell as put a stake in to support apple tree .

Thats including lunch break


Whits takin them sae lang

By the time you get there,it
MIGHT be ready 🤗

Drove up 5 minutes ago ...they are just bleeding the clutch apparently shouldn't be much longer ....got the a frame etc on the car meanwhile ready to go.

Your mum rang them and told them to drag it out so she could get you to do some gardening done. ::bigsmile:
