What a day, 3 new jobs to do this morning. All started ok but then my water kept stopping and starting! Checked the controller and the battery warning was flashing. Its only a couple of months old. Quick drive to the local towbar shop and they checked the split charge, all working....put a load on the battery and it was dropping big time. Knackered and needed to get back to work so had to buy another. Have gone for 110 ah now So £50 of windows..... £90 battery!!! Not happy......but had a silver lining which i will post as a separate post!
