The adjustment of the distance between the magnets and the copper reels is made by using the nuts on the side the bucket side. The magnets should pass as close as possible of the reels but without touching them.
To test, quickly turn with your fingers the end of the metal rod. If the led does not light, check the contacts.
If you are using a water jet, it's better to be two to operate. One holding the bucket and the other one aiming at the turbine with the hose (don't be afraid to get wet!). 
- Here is a little video of the turbine in operation. The current of a stream is sometimes sufficient.
