I recently pulled the electrical box off of my SP-15 and being the clever individual I am I marked all the wires with tape. Unfortunately, as I was cleaning the motor up the tape fell off. I think I have the wiring correct but I want to be sure before I flip the switch and risk burning the motor up. I have attempted to draw a little diagram above with how I think it goes but I would love a second opinion. I seem to recall the ground was connected to the metal of the box itself, but not being 100% worries me.
