Results You need a shop repair manual I do believe, Ferris does not offer manual. If you look through these manuals electrical schematics are included.
I do believe Briggs & Stratton owns Ferris, you can email or call them at 1-800-744-8650 m-f from 8:45-5:30 and see if they can sell you a shop repair manual, be sure and have all numbers, model, serial, as well as all numbers from engine at hand.
