Finished all the assembly and wiring. When I was about to start the sugested tests to be done before powering, the fan acts bizarre.

Video

Is this normal or have I done something wrong on the wiring?

Hi

This happens on my Reprappro Mendel too. I assume as you move the carriage you are driving the motors. They act like generators. The fan is always in the circuit so the LED lights up.
