According to the instructions for the StewMac kit, you shield the coils and replace the wiring, etc. That's why I was asking about it.
"Wrap the coil with a strip of black electrician's tape. Start in the area of the two lugs on the lower bobbin plate and be sure to overlap the tape at least 1/2". Prepare to wrap the coil with the 1/2" copper foil tape by trimming it down to 7/16" then cutting a piece long enough to wrap once around the windings and overlap itself by 1/4". Remove all but 1/2" of the protective backing and start to wrap the foil around the bobbin. Start with the end of the foil that still has 1/2" of backing on it in the area of the solder lugs. Wrap the tape around the bobbin and overlap it over the part that still has the paper backing. From outside to inside in the area of the wire lugs you have the following layers: foil, foil, paper backing, black tape, black tape, windings. The paper is left in the area of the overlap because it reduces the risk of getting the area too hot when soldering and shorting out the windings. Before soldering you will want to check to be sure the cover can still be installed."
