Invar fluxducts connect dynamos and redstone flux cells just fine, but if you go redstone flux cell>fluxduct>item receiving power, no power is sent, even with correct setup of sides on flux cell. This works: Dynamo>fluxduct>item receiving power... Maybe i'm using it wrong?

Use a Crescent Hammer on the fluxduct on the right connecting the RF Cell.

This was fixed by shift+right-clicking the pipe closest to the power source with a crescent hammer. Thanks again!
