place a Redstone engine down, and try to turn it
Additional information: happens to all engines

In the current versions engines can only face a machine or pipe that can accept the power that they produce. Can you upload a screenshot of your engine and what it's next to?

can you show some pictures of your setup? sounds like they may not be facing something that can accept power from a redstone engine
