Leisure Battery Talisman 1997

Post by Daisytalisman on Sun Aug 14, 2016 6:22 pm

allthumbz Hi All
We have had our van a few years now and replaced the leisure battery last year, we have been away for the weekend and believe it or not the first time without hook up. The battery only lasted an evening, I feel we must have done something wrong, there is also a panel on the wall next to the clock and heater switch that has something to do with the battery but we have never found out what it does, should we have turned this on? You probably think we are rather stupid and you're probably right, but if someone could clarify this for us we would be grateful.
Many thanks
Fiona

First you are not stupid or you wouldn't be asking Why

Was the battery fully charged(recently) previous to your trip
What appliances were running and for how long - heating,tv,etc

We drove for around an hour and half to our destination, but the van had been stood a few weeks prior to this. I expected the journey to charge the battery. We had the water pump on and filled a sink with water and the toilet flush, we had the light on for a around 10 min max.

Were we supposed to have the battery switch on the wall switched on or is this just an indicator for the battery power?

The main problem here is that A/S change the location, function and appearance of their electrical (and other) controls regularly during production, so nobody here really has any certain way of knowing exactly what your "panel on the wall next to the clock and heater switch that has something to do with the battery" is or does.

You stand a much better chance of someone recognising it and being able to tell you what it does if you post up a photograph.

Generally, the battery gets charged in 2 ways - via the "split charge relay" when the engine is running, and via the built-in power supply when you are on electric hookup. These are independent and either (or both) can fail. It is not uncommon for the fuse on the split charge to blow if the leisure battery gets into a very low state of charge, and then the blown fuse remains unnoticed when the battery is replaced - so you then don't get any charge into it while the engine is running.

Something wrong there. That’s a tiny drain that should have had very little effect on the battery capacity.

I can’t think what switch you mean (picture perhaps) I only have one battery switch and that switches the 12V system off completely. Have you got a button to press  with a red or green light to tell the state of the battery and if so is it red or green?

Since the 12V system works there are only three possibilities really:

Battery not charging properly

Something permanently draining current that you don’t know about

Duff battery

Whatever it is you’ll need a to get hold of a meter and do a few measurements, otherwise you can only guess and could end up spending a lot of time  (and possibly money) for nothing.

I’d start with measuring the voltage of the leisure battery when the engine has been running for a while, It should be around 14V. The next step will depend on the result.

How many weeks is "a few", and was it on hook up during that time?

It's quite possible that even a small drain on the battery could virtually flatten it over a period of weeks (and there are always some small drains), and they don't like it!! It may have been damaged beyond resurrection, but try the various suggestions to eliminate the uncertainties and reach a diagnosis.

Even if the battery was fairly thoroughly stuffed, I would expect a bit more out of it than you got after a 90 minute run - assuming it was being charged as it should be.

Yes and it’s not always obvious that anything is left on permanently.

I was doing a bit of testing on my van a few months ago and I was surprised to find a small constant drain on the leisure battery (about 30mA from memory). It wasn’t a problem for me because the van is never left for more than a couple of weeks but if it wasn’t used for months on end the battery would certainly suffer.

The question was why? OK I can understand it with the starter battery because the alarm is on but the van has no fancy control panel or anything else connected to the leisure battery that I would expect to be “on” . scratch head

Anyway it turned out to be the heater. It seems that the thermostat / switching unit is on all the time. I know the heater has an “over run” and stays on for a while after you switch it off, to allow the fan to complete the cooling cycle but I can’t see any reason why it shouldn’t switch of completely after that. After all you need to operate a physical switch it on again.

Thanks Brod. I had not thought of the heater control staying on to monitor temperature.

Hi
Thank you for your help, here is a picture of the switch on the wall, this was green when I arrived back but now it does not light up, the 12v was left on and so was the water pump could this cause it?

Opps duff link (are you using Safari by any chance). It seems to link to a picture on your machine. it needs to be moved somewhere with public access (photobucket or similar) before we can see it.

You link reads:

It could but It's not the most likely suspect, normally you would hear the pump if it was left on. If it's drawing current and not pumping it's likely to be seized (in which case it would probably take the fuse out anyway).

Do you have a meter to hand ?

That is the switch / thermostat control for the gas part of the Carver water heater. If that has been left switched on, it will have been switching the gas burner in the water heater on and off. It will have been using up your gas too.

Hi Frank, how do you use this, I thought it was for the battery? What does each sign mean?
Thanks

Top button switches the Carver on, the bottom one switches it off or resets [should it fail to light].
The lights, left to right IIRC are:
Left - green - lit & running.
Middle - red - battery voltage too low to light/run burner.
Right - red - flame out.
Long time since I looked at mine.

Thank you for your advice, I will give it another go making sure it's charged and looking at what's switched on and what could be draining it.

Many thanks

Hi Winky12
That would be fantastic thank you and very kind, we haven't got any instructions at all. We only know what we've worked out ourselves and what we were told be the previous owner. Can you send it electronically or would it be paper.

Kind regards
