So I'm currently in fairly early game so I just set up two water mill towers wired together with ultra low voltage cable to an MFE. When I first did this the MFE was fairly close to the mills but now that I've built a separate machinery house with all my electrical stuff under the floor, the cable has to travel a little bit more to reach my energy storage. The problem I'm running into now is that my MFE and Batbox aren't being charged! I've included a couple of pictures just to show you what I mean. Any ideas?
