Hi Everyone: I'm currently setting up my first grow. I'm copying this cab from the DIY section. Anyways, I just got a Dayton Blower in the mail and it doesn't seem to be working. It just hums but the fan doesn't move. I just want to be sure I have the wiring right before I contact the seller. I'm trying to power the blower with an extension cord that I've cut open. The extension cord has a black wire, white wire, and a green wire. There are two black wires in the electrical housing box of the blower and there is a ground wire coming from the motor that is screwed to the frame. I connected one of the black wires from the blower to the white extension cord wire and I connected the other black blower wire to the black extension cord wire. I didn't do anything with the ground. When I plugged the extension cord in, the motor just makes a buzzing sound; it doesn't spin. I also tried connecting the extension cord ground wire to the frame of the blower and the same thing happened. Am I doing something wrong?
