My battery monitor light has been going to red and back to green a few weeks now. Now it's constantly on red. My lights are dimming and I think it will die. Plugged into 240 ran fine until lately. Changed fuses charger light on. Any help so much appreciated.
The only way to find out what is going on is to measure the battery voltage. It sounds to me like the battery charger may be faulty. If you have a multimeter, or can borrow one, measure the battery voltage with the charger switched off, then get someone to switch the charger on while you hold the meter leads on the battery terminals. The voltage should rise significantly when the charger is switched on. If it doesn't there is a problem with the charger.

During this time was it plugged into the mains for charging?
Your electric hook up feeds mains electric to your caravan. This feed goes to the control panel where you will have a RCD and 2 or 3 MCBS. The power from the MCB's is distributed to the various electrical appliances in the caravan, one of which is the caravan battery charger. You need to find the charger in your van, hopefully in the caravan but near the caravan battery.There should be be a plug leading into the charger and leads going from the charger to the caravan battery. If you have a voltmeter/multimeter take the volt readings going into the charger and then check the voltage on the leads going to the battery. If you are uncomfortable with this best get a mobile caravan mechanic though this will cost.
Is there any chance at all I'm using too much electric on appliances that enough isn't getting to the charger? Will ring a mechanic as I will probably break something hehe thank you for help!
If you were running too many high current appliances like kettle & fan heater the site ehu would trip. It would not harm the caravan electrics. As pointed out. It sound like your charger has failed. A caravan transformer/charger costs around£100 & probably about an hours labour charge for fitting
First job would be to check the battery for fluid (if possible) then check connections, maybe take the battery and get it checked out.
If all ok and if you're not into electrics get a service type person to check out the mains.
sounds like the battery is charging ok, but it might be at the end of its life.
i have a battery at the moment that charges fine and shows as fully charged, and when i use it it seems fine. it just doesnt last long, and wont hold charge after 5 days, so it is almost dead!
A quick test on it finds that at fully charged the voltage is low, so while the charger thinks its charged, it really isnt.
new battery in situ, and all is well now
so charge it up and test the voltage. see if it holds its charge for a day and see what voltage you get then.
also be aware that a dying battery is going to put extra pressure on the charger and could wear that out if you are not careful

So green light back on with lesser use of appliances that use battery, does previous advice apply still? Must be charge going in.
This makes it sound more likely a battery problem so check that out first, also check to see if its warm/hot
