Well I have left the EHU for 24 hours after putting the rocker switch to on. I have since taken a reading and the battery is now sitting at 12.7v ? so does this mean it is fully charged?

If so it seems that by not putting the chrome switch to ON I was isolating the current going to the battery and it wasn't charging.

Sounds good so far but can you now flush the loo

Not tried the loo flush yet but will do after work tomorrow. The Impulse control description is as follows:
Product Description

The Reich Impulse battery charger which can charge wet and gel batteries with 12v. High frequency technique. The Impulse is a fully automatic, computer controlled and safeguard power supply and charger (Functions also without battery). The safety of the impulse is guaranteed by means of the quality mark TUV/GS designed with double insulation.
In the case of voltage drop on a large campsite e.g. 200v instead of 230v the units will still charge at the correct ampage helping to avoid damage to the leisure battery.
Weight 1.5kg
Can be used as a power supply without battery
Suitable for all LED and gel batteries.
Automatic overheating reset

As the battery was flat and the motor mover still worked without EHU, it must have some power to make the mover work as it says functions without battery?? I can't understand if the battery was low why the mover worked and the symbol on it is reading as fully charged even when I had the leisure battery Isolated by the switch.

It seems you have some strange arrangement there ............ if you recall I did say I could not see the charger leads going to the battery? maybe they go via that switch?

The black box I called No3 seems a very strange piece of kit?

Hi Hob, the switch I have to put to on if I want to use the Leisure battery for power to the van. If in off nothing works and the battery doesn't charge.

I checked the leads you mentioned and they are also connected on the Leisure battery so not astray.

The wiring runs like this: EHU to the mains unit, that runs to the white socket, grey Reich charger is plugged into socket and the red/black runs to the Leisure battery terminals. The other plus into the socket runs to the black box with the chrome rocker switch which isolates the battery and nothing works off EHU unless it is switched on and it seems that it needs tone turned on when on EHU to allow the trickle charger to work.


Thanks everyone for all the helpful replies, I shall check the loo flush off battery tomorrow and see if it works with full battery power.

That is what i thought it should do

Ok so the black box seems to be a transformer changing 230v ac mains power to 12v in one switch position, from the mains via the socket, in the other position 12v from the battery ........... seems logical

Thats the bit I don't understand I would have thought the charger would have worked all the time the mains was plugged in either to charge up or maintain full charge.

Maybe it was just not plugged in to the mains for long enough to keep the battery charged?

Thanks Hob and everyone for the help, it's getting there, but I would have thought like you that the black box switch would isolate the electrics but the Leisure battery would have always been connected to the trickle charger if on hook up. Now that I know what I was doing wrong at least it is charging and I am now up to 13v.

I had visions on having to push it off my drive which would not be much of a problem but good to see my battery is now reaching power although I won't unplug it yet and try the loo pump.

Does anyone know if those led displays connected up take any power away from the battery as I might get one so I know when to put it on EHU to keep it topped up after this exercise.

I now have a full battery and I also have a toilet pump working off the battery. I think it was urn ME. I had not pushed the button for the pump in the sweet spot and was a little to far over so it wasn't depressing enough to turn over the pump. When my thumb was in the correct place it all worked fine. Thanks all for the help finally I got there.

Hi Hob got the Pump out but pulled the end out of toilet accidentally put it back it seems a bit lose i cant see if it clips from the back the strong pipe seems to hold it in place, Wash it out with lots of water till it ran clear ( freed the pump by turning it with small screw driver) Thanks for Info Alan

Freed my Pump with small screw driver turning it Round, But pulled the fitting out of the toilet put it back it does not seem to clip tight back is this right , It works fine the strong pipe seems to hold it in position hope it does not leak

Using the Eriba on the last outing the toilet impeller had again failed to work but the electric button was powering. Lats night I put a warm water Solution of Puriclean into the flush tank and left it to work, this morning it was working again but then seems to struggle as it drew some water through. So I left it for anothe r8 hours and the pump is again working on full power and flushing well. It would seem that any little bit of the pink stuff left in the system jams up the motor so it is worth after every trip soak and flush through the tank out with Puriclean to ensure it does not clog up.
