Its shows battery charge of both leisure and main batteries with 4 lights each (4 means fully charged and 1 red means almost empty).12v relays tend to click when they don't get enough power to maintain the latch.
Out of interest, does your control panel when illuminated show battery charge? If so, what does it show without any 12v items switched on?
I even went onto the copper of the cable...all same readingsmeant to have asked, when you checked the battery charge, did you put the meter probes on the battery terminals or on the cable clamps?
Worth checking the reading from the clamps as that gives an indication of the connection between the clamp and the terminal.

If a energise the panel, it lights up. When I switch on a light it trips out. If I try to reset the panel its wont as the light button is still pressed. I must turn off the light then the panel will reset. Same for pump or fridge.Remove the EHU and you can illuminate the habitation panel but as soon as you turn on either a light, water pump or fridge it goes dead. What happens if you then turn off the item and try and switch the panel back on?
Thanks for all the advice folks, its appreciated. Battery charging at home now, will pop it back in tomorrow and take it from there.Fingers crossed that tomorrow sees an end to your problems.
The simple check to eliminate battery problems is to leave your meter attached directly to the leisure battery terminals, reset the panel, then turn on a light whilst observing the meter. The battery should continue to read the same, or near enough, whether the light is turned on or off. If it does you have a poor connection - somewhere! If it doesn't, and drops rapidly as the light is turned on, you have a battery problem.To be honest I am back at the fact the battery isn't charged enough.
The one you have installed may have voltage at rest but could die under any load, if it was the one that was flattened by leaving the light on, then you should just weigh it in for scrap!
If your new battery is taking 13.7v from the charger in your house then it is in need of a good charging. I am afraid you will need to patient and wait till it is charged and then sling in back in and see what happens.
If you took it to a dealer, the first thing they would want to do is put a fully charged battery on it before doing anything else.
Fingers crossed that tomorrow sees an end to your problems.
Leave it charging as long as you can so you get a reasonable amount of charge in. It might also be worth seeing if you can charge up your old one as a back-up just in case.Thanks for all the advice folks, its appreciated.

Brian, I rigged up a different charger (Not normal EHU) and connected it to the in-service leisure battery.....it read 13.6v whist charging. Again I powered up habitation controller with charger still connected, but it tripped out as soon as I switched anything on. Same as before.We like a challenge.
So with your charger that says 75% what happens if you turn lights on with this charging, monitor the voltage. You should see 14V+ on charge.
Just tried this with old battery. It read 12.90 volts with panel lit up. Once I switched on light it stayed on for a couple of seconds then tripped out. the whole time the voltage stayed the same. Repeated a few times and voltage did not change too much.The simple check to eliminate battery problems is to leave your meter attached directly to the leisure battery terminals, reset the panel, then turn on a light whilst observing the meter.

I own a Ci Carioca 746 and its been running great until last week. I accidentally left internal light on and drained the leisure battery. Now it will not work off leisure battery. I recharged it and still my 12v system will not work in habitation area.
If the 230v supply is plugged in, the 12v habitation system works.
If the ignition is running, the 12v habitation system works.
But if I try to run on 12v leisure battery, the control panel illuminates but when I try a light/pump/tv the control panel dies. A relay sounds in the 12v fuse box and everything 12v shuts down.
Yesterday I bought a new 110Ah battery....same problem.
I really would appreciate any help as I cannot get a dealer to even look at it for next 4 weeks!

now I am confused..
the battery leads leave the battery and go under floor. There is no fuse on this section. I imagine they run to fuse box and again I see no fuses here. They connect to a pcb board via plug in connector to the pcb. Does this sound normal?There should be a fuse very close to the battery. If it has blown your battery status will not change but no power will be delivered beyond the fuse. This may explain why the fuses you have found and checked are OK yet you have no power for your services. It will be a dedicated fuse somewhere around 20-30 Amps.
This panel works perfect when on EHU or when engine is running. Could it still be faulty under battery?I think there may be something wrong with your control panel. It seems that the voltage is being misread and/or the low voltage trip is not working correctly

this definitely points to power not getting from the battery or the battery is duff as all your changing is the source of powerThis panel works perfect when on EHU or when engine is running. Could it still be faulty under battery?
Yes, I looked this morning at 8am it's still charging since last night. 13.4v now reading on charger. State is 3 of 4 bars. So a bit to go yet.how is the charging of the new battery coming along?
Unfortunately, I am not familiar with your model of motorhome or it's age. However, I would be surprised if there were no fuse on the positive cable and within 1 metre of the battery terminal. On my motorhome (Autotrail|) it's about 9 inches away and in my experience a very common practice as it is safety related and may even be driven by some form of regulation/Code of practice.the battery leads leave the battery and go under floor.

OK this is my battery connection with cables and vent going straight through the floor.It might help us make better guesses if you post some decent pictures of the battery connections, the panel and that control board.
It's an interesting one for sure and must end it "why did it take us so long ?".
OK this is my battery connection
