Quick Reference Guide - Fairbanks Morse Parts Identification
Magneto's have been used on gas engines since the 1800's. Unlike conventional battery ignition (like automobiles have), magneto's do not need an external battery to start and keep the engine running. Therefore many mag's will be found on older engines that are started by a rope or hand crank. Some engines like many Wisconsin models have an external 6v or 12v starter and equipped with a magneto. It is important to remember that you should never put battery voltage to the mag ground wire EVEN MOMENTARILY, as this will burn out the mag coil. Also when replacing your keyswitch or on/off switch be sure to get one with terminals for "mag to engine ground". This is a totally independent circuit in the keyswitch not related to the starter solenoid.
Our specialty in this area is all parts for all magneto's installed on Wisconsin and Continental engines over the years. However recently we have expanded these offerings to cover replacement parts and complete magneto's for all engine brands. Go here for a partial list.
We can supply magneto parts and units for most brands of magnetos including Bosch, Eisemannn, Fairbanks Morse, IHC, Slick, Prestolite, and United Technologies, and can offer replacement units for such brands as Edison-Splitdorf, Eisemann, Bendix, and Case. Our magnetos are available for hundreds of engine applications for farm and industrial use. See below for ordering information.
