Having both rotors side by side was critical. Both rotors had a "starting point" and that was going to be my reference. (see the small commutator with a small trimmed wire tip sticking out)
I have marked the starting point as Red, then the next ones blue, white, green.
I starred at both rotors for a good 2 hrs until i knew how to rewind the burnt up coil. It's not easy as the wire can cross each other along the way.
With the old burnt up wire removed, i then took measurements and made sur the windinds were still isolated from the frame of the rotor.
The tricky part is to open up the wire clamp part of the commutators. This is the copper part that pinches the wires. When putting in a new wire, you have to use sand paper on the end that will get clamp to get good conductivity. BTW: I have almost broke one of the cummutators when trying to pry it open. I have then used a worm clamp to hold them tight together. Use a utility knife blade and a small slotted screwdriver to pry it open.
