It seems as if I have opened pandora's box (once again). After examining the brushes on the voltage regulator, I can't seem to get it re-installed correctly. I've tried compressing the brushes with a flat-bladed screwdriver and pushing it in but the brushes always spring back out before the regulator is all the way in. This is most frustrating. Anyone have any tips, tricks, or techniques? Thanks in advance.
