One of the brush holders has a component...small capacitor... ten cent part. If somebody can identify the value of the component, I could fix mine now that I've replaced the control board and still won't start. I shorted across the component and suddenly came to life.

Anyone with info about the third wire (on mine is blue ending with a small copper clip) serves? This is connected off of the switch, labeled W5 on the circuit board. [Edit. It is a ground] I suspect it is a feed back wire for speed sensor? But where does it attach? Some wear on the abovementioned capacitor crossing one of the brushes. Anny ideas?

You see the copper bushing slot at the top of the picture (next to the guy’s index finger) from step 9? Directly underneath it where the slot sits, there’s a tiny notch in the gray frame. Once you pull off the bushing slot from the frame (if you haven’t already), slide the small copper clip (from your 3rd blue wire) onto that notch. Then you push the bushing slot back onto the frame where it was. Essentially, the copper clip is “grounded” to that bushing slot.
