Neil Yerigan ran a small electrical repair shop in Minneapolis for many years. His knowledge about old electrics was priceless, and he put some of it down in the book, How To Restore Tractor Magnetos. The book offers restorers important information about old stuff that hardly anyone knows how to work. Yerigan was also a fine writer and humorous man. That carries through in his book, as does his love of preserving, restoring and reviving old machinery.
