We have a new battery which shows"green" but the caravan electrics are not working. My repair man says I should be keeping the van plugged in at all times especially as we use a mover but this is our 4th year with the caravan and have only ever topped the battery up at home and then it charged fully on site so never had this problem before. We have replaced a bulb in the kitchen area and it is still not working even when on mains.....I think I have an electrical problem but my fully registered repair man disagrees. Can anyone help point either of us in the right direction!
