The LESU central block accept energy normally, but seems to be unable to output anything. Tried to place ic2 cables (not the TR cables, i have the option to remove overlapping items) on every side of the block, still nothing.
Using a lever for redstone signal, still nothing.

same in 1.11.2 (TechReborn-1.11.2-2.1.6.76-universal)
