Battery problem

Hi, I wonder if anyone can help please. We are away in our swift challenger 500, we have had for around 2 years now. On return from a day out the lights were dull & fridge showing spanner, on checking battery display on the ac50 power control panel it showed battery in the red even though we are on ehu.
We know ehu working fine & power lead as tried a different one. We checked all fuses in cupboard & all fine. Rocker switch is set to caravan.
So bought a new leisure battery 105ah and was fine the whole day/night. Went out for the day got back & again lights dull again, battery showing in red if just one light on, goes to amber with all lights off & just tv on.?

 

switched everything off but fridge over night and this morning battery indicator on low red.?

Seems that even though we on ehu, it is still not charging batter.Any ideas why.?

Need basic advice please as very novice to this.

Many thanks

Seems like the charger is not working. Maybe a loose lead, maybe a dead charger.

Thanks for reply Stevan

 

Is this something we could sort out or need a Specialist to do.?

It's not rocket science and anyone with decent DIY skills could do it, but the way you asked the question suggests that you may not.

Safer to get someone who understands what they are doing.

Quizzeyk, I’m puzzled by your mention of the ‘fridge. Is is switched to mains? Not knowing your wiring setup, but if it’s switched to battery it will drain it pretty quick as they should only work off the battery when connected to a car with the engine running. Perhaps try running the fridge on gas for a while and see what happens.

 

Another thing to look for is the main battery fuse which is often hidden away behind the charger ( mine was pushed underneath the battery box!).

 

Are you definitely getting power to the charger as the connector in the back of some of them (often known as a kettle plug) may have come loose.  

 

Finally, my van has 2 switches which must be on - one turns the PSU on (can be difficult to tell whether it’s in or out) and the other turns the charger on (it goes green).

 

Good luck, John.

Hi John, thanks for your reply.

 

Fridge is set to electric not battery, and ehu icon showing. However when battery disconnected fridge goes off.? 

 

We we have checked the fuse, this was under our fixed bed behind the batter box and it looks fine. 

 

No idea if we are getting power to the charger, how can we tell.? We assume not hence why battery running flat even while we connected to ehu.? We have ensured all fuses not blown, made sure switches in correct position etc but still battery drains. We have had a look at all connections we can (no kettle leads) to ensure every connected / not loose.

 

just stumped

The 12 v position for fridge is for the car battery when towing and not for battery in caravan.

What year is your caravan and which power supply unit do you have in your van? Is it the ESM4 or the NE143

Many modern fridges require a 12v supply for the controls, whichever power source is used. The alarm is for this supply.
