Leaking current from leisure battery

[sidepod]

If that doesn’t work then the supply is permanent via the battery monitor unit J934 which you can see is hard wired to the leisure battery.

So this fuse I pulled:

I find it hard to locate the fuses in the diagrams, as the fuse positions do not seem to be numbered or anything.

So pull all of the 25/30A fuses one by one till the light goes out!

 

[Resfeber]

Can we just recap a bit as I can understand this is getting difficult with no clear fuse numbers.

The Fuse SH25 mentioned by @sidepod is a 30 amp fuse and is located under the passenger seat (right hand drive vehicle) or drivers seat as the OP is in the Netherlands.

Without any clear fuse numbers it is difficult to locate other than it has a good chance of being one of the 5 visible in the image.

The SH fuse list description
for fuses 1 to 12


follows the fuse rating sequence in this image hence The label for fuse 1



So as we are looking for a 30 amp and as @sidepod has just said pull each 30 amp in sequence and one should extinguish the inverter .

My money would be now on this one

 

[sidepod]

Or pull this one if it’s easier to locate?

 

[sidepod]

My gut feeling is pulling the fuse won’t extinguish the led. I think it’s powered via the purple/white striped wires from the battery monitor unit J934 which is hard wired to the leisure battery.

 

[sidepod]

Purple/white is the LINbus network (12v/neg) so I’m guessing it is battery monitoring.

For simplicity would the removal of this terminal block connection from the inverter not resolve the matter by taking the inverter unit out of the system and see if the OP’s battery drain issue stops then over to dealer to resolve?

I’m in the van now and I just pulled all the 30 amps fuses. None of them extinguishes the green led in the socket

I like that idea but how to remove that yellow socket? I’m trying but don’t want to break anything

As I suspected.

If there is no fuse in the line then it’s supposed to be on and probably isn’t the cause of your drain.

240V in-vehicle supply - is it good? & HOW TO GET YOUR PLUG TO SIT FLAT

Hi folks. I was not aware that my August 2021 California 6.1 had an inverter but a trial plugging in of a camera battery charger to the 3-pin socket on the centre-side of the driver’s seat suggests that it does! Which kind of makes sense now given discussions I’d seen before of how well the...

But your green light is NOT on right?

Btw, I was able to remove the plug from the socket

Possibly

Ok so repeat the charging process and see if it behaves differently.

Having travelled this far with you on this issue, do please report back on how your leisure battery charge holds up with the inverter unplugged from the vans systems

 

[Resfeber]

But your green light is NOT on right?

Also have a look at California Chris’ video in the link above No green light on his.

 

[sidepod]

What does the manual say about the green light?
There is a “i” icon next to it.

The manual say
LED display above the socket Green light permanently on: The childproof lock is unlocked. The European power socket is ready to work.

 

[sidepod]

So it’s not that causing your drain.

 

[andyinluton]

So it’s not that causing your drain.

Sorry I disagree.
The green light on means the child lock is disabled.
The way to disable the child lock is to plug something into the socket.
The inverter thinks something is plugged in & is therefore turned on.
A normal unused socket does not have a green LED lit. Putting an adapter in will make it light up.

What @andyinluton said. Here's a screenshot from the manual:

If you've got a green light the inverter is snacking your battery energy. The microswitch switches the inverter on. Disconnect the 10 position plug at the inverter end and you can check for a short between pins (double check -- I posted it previously) 6 and 7. If shorted get them to order a new socket under warranty. The socket contains the (faulty if pins 6 & 7 are shorted) microswitch.

Edit: pins 6 & 7 for the microswitch confirmed.

Edit: @sidepod has been a bit naughty and posted a few diagrams for a previous version of your vehicle. Take care when looking at diagrams.

If pins 6 & 7 are shorted you can leave that 10 pin cable disconnected and the inverter should remain off.

Agreed. My bad.

I disconnected the 220 V socket and indeed the drain seems gone now. I charged yesterday evening, I need to give it some time but so far it seems promising

 

[rjurgens]

Stuck microswitch on the Inverter?

@WelshGas @AlanC You guys are the best - I removed the plug from the 230V socket and now the batteries stay fully loaded
