Back to the lab again....

Love the new wiring boards, more in depth, more real. Didn't take to long to wire everything up and working right but I didn't do it right according to the diagram, so I had to rewire. Made my 30 on the relay always hot but that's not how the wiring diagram had it. It actually is a switched ground so had to do some backtracking. Found a video on YouTube that explained the basics of a dc motor. Never knew that the polarity jumps back and forth, but that's why were in school cause we don't know everything. I didn't expect some of the current flow readings i got either but i will update on that.
