These engines were built for use with Western
Electric lighting equipment. Most were sold under the Western Electric
name but complete outfits were available from Fuller & Johnson starting
around 1919. Engines equipped with a magneto were used for direct
lighting purposes only, those without used electricity from the storage
batteries they charged for ignition. As with many engines manufactured
in the day, the Wico EK magneto became available in 1924 for direct
lighting units. Light plants were still available in 1931 and presumably
available right up until the end of engine production 1933. The 8M and
15M direct lighting units were available in both 32V and 110V. The air
cooled kerosene burning light plant engine itself featured a unique
splash oil system that was kept filled by a small oil pump. Both Titan
and National batteries were available in 80 to 315 ampere hour sizes.
