..........As I was thinking about it I might try to pull a bigger cable through rather than use doubled 6. Not sure if 2x16mm2 fits in the same space as 4x6 though. Have to go find some cable to measure first. I only find core diameters online.


Spirou,

On 12voltplanet website & in Vehicle Wiring Products catalogue, thinwall 16mm cables OD 7.9 mm & 7.5mm are quoted. Hope that this helps.

Alan

If the same behaviour doesn't happen with the battery completely disconnected then do as I mentioned earlier. Take a multimeter on current mode and start pulling fuses/wires. But if this is recent development it is probably more likely to be a dead battery so charge, disconnect and measure after a day or more. Remember to pull the fuse from the solar regulator before disconnecting the battery.

Fesspark, that makes me wonder if the battery is actually being charged at all by the inboard EHU charger?

Are you sure the charger is working, what voltage and current are you seeing on the Display Panel when the charger is switched on? This obviously needs to be done when no other charging is taking place, like Solar, etc.

If the charger has failed and your 'backup' battery is down at 12v then it may not be as good as you thought?

I think it is possible that the charger is,nt working? When the sun went down, the battery went immediatly to 12.2 Reading?It also went down after I disconnected the Electric hook up after 24 Hrs.? If thats the case whats the likely cause and can I rectfy it or do I need the warrenty people to deal with it,as I was planning a short trip for a few days fesspark

Cover the solar panel (or remove the fuse), plug into EHU and see if voltage rises.

I don't know what EBL is in your van, but if it is a Schaudt EBL, the charger is probably inside the EBL.

Some basic checks that might help -
On your display, is the mains indicator on?
If yes, then check the charger output fuse on the EBL. On my EBL223, it is a 20Amp fuse labelled "Int Lademodul"
If no, then check there is mains power on the IEC "kettle" lead that is plugged into the EBL. Maybe a breaker has trippedor the plug is loose?.

If there is mains power and the charger output fuse is ok, then it looks like the charger is at fault. There is an 3A fuse on the mains input side, but I don't think you can access it without removing the EBL. If this has blown, there is probably something wrong with the charger in any case.

I'm in the middle of a test on my 5 year old gel batteries which have been heavily used for 4 months annually, half of which whilst on skiing trips using very little hookup.





Kevina, We are always trying gather more information, so wondered if you would share what you found with the Gel battery testing you planned to carry out a while ago?
