Ci cusona leisure battery not charging on hookup

[coliwogs]

Disconnect the EHU and put your meter across the leisure battery terminals with the engine running and check the voltage reading , it should be about 13.5v + (with the solar disconnected/ covered / in the dark)

Yep goes to 13.6 when engine running

Is it one of these? ANL strip fuse

Strip Link Fuses

Strip link fuses used for protecting larger current circuits in automotive, marine and leisure applications. Available in current ratings from 30A to 100A.

If it is, it looks like it's OK, ie not blown.

Yes it’s one of them lol

Is there a 12V distribution box somewhere, with some standard 12V blade fuses? There should be a 'split charge relay' somewhere, probably in that distribution box.

A relay is an electrically operated switch. It connects the starter battery to the leisure battery when the engine is running, so that the alternator can charge them both at the same time. It disconnects them when the engine stops. That's so if you flatten your leisure battery, you can still start the engine.

There is a big fuse near the starter battery on the wire going to the split charge relay, and another big fuse near the leisure battery, on the wire going to the split charge relay. Both of those fuses must be OK, because if even one of them has blown, the leisure battery voltage would not rise when the engine is running.

All this is pointing to the mains charger, its wiring, or a fuse in the charger wire, as the problem with not charging from the mains on EHU. There should be a block of standard 12V fuses somewhere, worth checking those.

The power supply in photo looks the same as mine, the fan only runs when it’s working hard. I would put your meter to main volts 300v ac and check across brown and blue wire, and check you’ve got 240v going in? Only speed read the thread so sorry if I’m repeating do your 13amp socket work?

I have a 2004 ci carioca it does not charge the cab battey on ehp you proberly need a battery master

Not being picky but should that be 300v AC

Edited thanks

Checked all the blade fuses and they are OK. I will get a picture of the distribution board of sorts. It is a mess of wires, don't even like touching it incase i pull one lol

not the cab battery I have the problem with

Is there a fuse on that power supply, or maybe inside it?

Not on the outside. To undo the casing I will need to remove the drivers seat first. Was saving that for my last option lol

The Arsilicii AL C20 unit is described as a fuseless switching power supply , so maybe has non replaceable fusing ?

 

[DandG5515]

Picture of my breaker ON in same position to yours. It just feeds black junction box below (and everything 240v in the van) no fuses that end on my van. One of the cables in my junction box feeds directly to the power supply, hence why I asked is 13amp sockets live.

 

[DandG5515]

On mine the power supply feeds direct to battery and does not go to this fuse box

Are you getting voltage out of the charger - the red and black wires? Can you get the meter probes into the connector pins without separating the connector? Might be difficult. The trouble is, sometimes chargers are a bit too clever, and if they don't see a battery connected, they cut off the output power. So no voltage out might not be a charger problem, it might be some connection/fuse on the connecting wire.

Can you trace that output wiring all the way to the leisure battery? There should be a fuse on it, near the leisure battery. It could be one of those metal strip fuses. The charger output is 20A, so the fuse will be more than that, probably 25A or 30A.

Sorry. Even out all day. Thinking about it now when I put the new leisure battery in months ago I’m pretty sure there was another one of the fuse blocks that I checked this morning. I will have to wait till tomorrow to have a look now. Thanks for all your help
