I think I might have found the problem. It seems like there's a fuse in front of the first leisurebattery aswell on the T6.1. As you can see on the picture 12.8v is consistent with what I measured with the multimeter on the 2nd leisurebattery in the back. And 12.4v is equal to the measurement from battery 1. I have not seen this kind of fuse before, does anyone know what it's called and if it's hard or not to replace?
