Hi there, I am not an experienced machinist or electrician; my apologies if this is obvious stuff.
I bought a used HG 44911 a while ago, and have had problem with it from the start. The pot was damaged, so I ordered a replacement from the Littlest Machine Shop.
Unfortunately, the little labels on some of the wires fell off while I was waiting for the replacement, so I had to figure out the wiring from whatever I could find online. While I think everything is right (certainly the P1-P3 wires look correct), no matter what I try I can't get the potentiometer part of the speed control knob to work. The spindle does not move at all when anywhere in range of on positions, and runs at full speed when the knob is clicked to the off position.
I'm at a bit of a loss as to how to pursue fixing this. My biggest concern is that the wiring is wrong in some way that is dangerous.
