Leisure battery problem? (2 Viewers)

[Hamish the highland hymer]

Hi im new to the site, and have not long bought a hymer b544, which i love, ive done my maiden trip
But on my return saw that the engine is not charging the leisure battery infact the voltage drop when the engine is running,
It charges from mains hook up and get power from my solar panel but with the engine on it appears to drain the battery quite a lot.
Any ideas would be great
Thanks
Mark

welcome Hamish. I'm afraid electrickery is not my bag but one of our resident electrical genius's will be along shortly no doubt.

Engine on, big drain says Fridge. This should be from the engine battery.

Possibly the engine and leisure battery connected the wrong way round in the electroblock.

Hopefully its something silly
Thanks

It did charge fine when i bought it and havent tinkerd at all and was fine on my maiden weekend away.
However i was in abroad for ten day during the snow and now im back seems have developed this hiccup

On our Hymer near the engine main battery is a block of 3 fuses, one is yellow 20 amps and is used to power the fridge while travelling, there is also a 50 amp and a 5 amp . I would check these to see if it one has blown as these may charge the leisure battery

That's the end of my guessing then, time to bring in the multimeter.

Stick a meter across your battery with the engine running, sounds like your alternator is knackered.

I had this problem some years back where the split charge rekay was operating with the d+ alternator but a fuse had blown between the starter battery and the split charge relay so that on starting the engine the fridge was being powered from the leisure battery

Thanks done that, engine charging ok saying 14 ampstry the fuses then at battery

Don’t mind helping even if you are a Weegie.

Aye but on further investigation he isn’t a Weegie, he is a Scouser.

OK. I'll amend that to

I hope it’s not my bit of outside Glasgow, I’ll need to lock everything away.

Was going to help until you said that Oh Ok then, just this once...

When you say 14 amps do you mean 14 amps or 14 volts? All due respect but there's quite a few don't know the difference. 14 volts is about the expected charging voltage, and 14 amps is about the expected amps for a fridge on 12 volt power.

The alternator on my Hymer, supposed to be extra powerful?, shuts down when it feels like it to save fuel, so my leisure batteries are never fully recharged by driving.

You can fit a battery-to-battery charger between the alternator/starter battery and the leisure batteries. This will load the alternator in a way designed to make it think the starter battery is not adequately charged, so it sends out more power. This power is transformed into a suitably high voltage for charging the leisure batteries until they are full. When full, it drops the voltage so that there is just a trickle of charge going to the leisure batteries.

As you have a which I assume is on a B680 on a Merc, Hymer will have fitted a Schaudt unit that overrides the smart featurers of the alternator so your batteries will fully charge.

That is what I understood should happen, but the manual says on EHU full charge to the leisure batteries and a float to the starter (2 amps) .This is reversed when the alternator runs and after the starter battery is fully charged periodically switches off. I have a voltage display plugged into the cigar lighter socket which suggests the alternator does not run for long enough to charge the leisure batteries (3*ldf90's)

This new member has come on to ask about a problem they have and after they have ran out of free questions disappeared up their do das, personally I’am getting fed up of these type of new members. What does anyone else think ?

Unfortunately as long as Jim allows a few freebies it will continue.
Some subscribe at their first post , some subscribe after five free , some try to cheat and re-register because they didn't get the answer to their problem ......most simply disappear.

But, annoying as it is, without a free taste of what the forums like even fewer would subscribe.

Maybe we need a name for them, errrr, errrr, something in my head keeps saying FLT what can that mean ?


PS.... I didn't type Fork Lift Truck of course and when I add this PS it does not say Fork Lift Truck. I've been Jimmed.

Don’t think you are far wrong.

 

[hilldweller]

Don’t think you are far wrong.

Maybe, maybe not, this is the only paid forum I'm on. Others just don't ask. It wasn't always like that, I paid something like £20 a month for a technical forum, for years, and was well pleased with what I got.

I have just vaped my flikr account because they've changed the rules and are demanding $40 a year for what was free. It's not that much but I see no reason to pay it just to show people my photos.

It's a strange old world.
