I've got 3 Electric Engines powering a quarry (I know, not the most efficient) and I'm having some issues with powering them. I've got 2 batboxes and 1 MFE as storage sources (see image), getting power from 8 wind turbines on the roof. Glass fibre cable running to the storage, and then double insulated gold cable running down to the engines...
The problem is when they are all connected like the photo, it will ONLY take EUs from the MFE, and never the Batboxes. I can use a wrench to turn the MFE, where the output is open, and THEN it draws from the Batboxes. But, not when they are all hooked up.
WHYYY???!!! ;_;
