Tam &Toby do Europe ...Take two

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 .

Do you want to come and sort my garden out?

 

[Northernraider]

Are you happy with it..

Ha ha i think so... although i only got it back at 5.20 and had to go straight to work so ive not had a poke about to see whats what.
But thats the thing with cambelt etc ...you don't really notice any difference ..only changed because 5 years old.

No thanks lol

My arms are hanging off tonight with moving all that mulch

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.

Obviously I'm repeating your test . The one thing I cannot imagine being the cause at this stage is the EBL. Off EHU it plays no part in charge control and isn't a source of power. That only leaves solar and alternator. If the over-voltage problem hasn't returned we're left with a possible low charge. Have you had any further thoughts?

Surely something detects the battery level condition though and adjusts what charge goes in ?

The mains charger and solar controller do this for mains and for solar so what does it for the 12v ?


Personally i really hope its not the ebl as its 300 quid...but im definitely not getting a decent charge from engine running

Obviously getting something but nothing great.

I'll check the voltages etc tomorrow

The alternator itself is a regulated source so when linked to the hab battery it just sees two batteries in parallel and charges them both as one.

The split charge relay is inside the EBL as is the shunt that is used to measure the current.

I will have to do the test at wires when running tomorrow as i forgot to leave all my lights etc on last night so all my batteries are at 100% this morning.

Need to drive the van to kirkcaldy for lpg today.

I'll make a point of leaving all the lights and tv on tonight when I go to work

That will normally bring the leisures down to around 80%

I agree but both are passive components. It's obviously possible for a poor internal connection to be the cause of the fault but either way it doesn't warrant replacement of the EBL. A very quick test to eliminate the EBL is to link the two outer terminals with the fault happening - which would require a clamp-on ammeter to watch the charging current or close monitoring of the leisure battery voltage to see any charging current increase.

Problem is I dinnae ken how to do that ....I'm fed up with it ..i just want it to work and not be worrying I'm going to be left stranded with no power and no heating etc in the middle of winter somewhere like last year

Did you take a gander at this thread ?

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...

fat haggis has just posted up pics of his controller after running his batteries down a bit .

Mine are at 100% 160ah just now so im leaving tv and all lights on from now till i get home from work at 11.30 . Thats a total drain of 4.7a so should bring them down a fair bit

I'll then see where the batteries are at and then I'll start the van in the morning to see what amps are going in again and check the wires you mentioned.

 

[tonyidle]

I have now. I'm not surprised with the hab battery at 65%. Problem when testing is that the readings are dynamic so there are a few things to be considered each time a test is made which doesn't help anyone unfamiliar with the problem. The charging current will be very different at 85%.
Let me know what happens with the test I suggested - there's more to follow.

No probs the thing is when my batterjes get as low as 65% I get nothing like that input from alternator and then I require ehu to charge up.

p.s .....its an absolute nightmare for someone my size to get to those wires though so I may well get stuck and no one will ever hear from me again

 

[Northernraider]

So when I got in tonight my batteries are at 82% 132ah and 12.4v

Starter battery is at 13.1 v

Will see what its reading in the morning before I start van up.

Come on Tam were waiting for your results!!!or

Calm doon man ...ive dogs to walk before i get on to that stuff

 

[intokenny]

Ah, of course, forgot about that, been awhile since ive had dogs.

 

[Northernraider]

OK so panel readings

Battery at 77% or 123ah
Habitation 12.5
Starter 12.9


Start engine ...+16a drops immediately to 11a then slowly over about 30 seconds to 5.6- 6a ...and settles after a minute or so at around 4.5 - 4.6 a
Hab and starter reading 13.4v



So at the 3 wires going in to ebl

13.94v at both sides

Cigarette socket 13.9v

tonyidle Lenny HB

 

[Northernraider]

by the way that is almost impossible to access those wires whoever thought of mounting that ebl there is a damm fool

 

[Northernraider]

Engine running approx 10 minutes
Now reading 125ah
Hab batteries 13.5v
Starter 14.1v

+5.0a

[fat haggis]

Did you disconnect the solar Before the readings. It should be full wack to 80% then on a float charge

 

[Northernraider]

Yep the solar was disconnected yesterday around 4pm

 

[Northernraider]

currently at 78% 126ah and with 3.8a input from alternator

 

[Northernraider]

So about 20-25 minutes now. 79% or 126ah both hab and starter batteries reading 13.3v
+2.8a from alternator



Rev engine that does rise back up to around 4.5 - 5 a again

 

[Lenny HB]

That no right.

^{_{Subscribers  do not see these advertisements}}

 

[Northernraider]

So after 50 minutes of engine running this is the current panel readings

Connecting multimeter at the 3 wires from ebl still 13.94v at both

And 13.9v at cigarette socket ...and same at the one i have connected to the habitation

 

[Northernraider]

That no right.

Well guys you can let me know your thoughts.
After 1 hour its raised it from 123ah to 128ah

But I need a shower so ive switched off engine just now and plugged hookup in so I can heat water

Ehu connected + 7.4a ( I expected higher)
Battery at 80% 128ah
Hab 13.6v
Starter 13.7v

Water immersion and fridge running also on 240v so that might affect input voltage

 

[Lenny HB]

You are only getting 7.4 amps EHU because the batteries are up to 80%, you only get the full output from the charger when the batteries are really low.

 

[Northernraider]

Cool

Is it just me that thinks if chargers would just put out higher amps all the time then the batteries wouldn't get low
I mean i only use around 15ah per night so i wouldn't get below 80% if it charged it up quick every day .

If i don't replace in a day what i take out overnight then its obviously going to get low.



Anyway I've had my shower so EHU is disconnected again and I've plugged solar back in ..

Its cloudy and raining here so im only getting 1.5a from that at the minute

 

[Northernraider]

Someone wake up tonyidle I'm awaiting my next instructions.
