Replacement ONAN Generator Circuit Board
Flight Systems part number 56-C859-00 is an improved, direct replacement for the main control board used in the Onan CCK & NH (RV) Series Gen Sets.
Features include improved components, heavy duty rocker switches and heavy silicon based coating (to protect against corrosion - a major enemy of any RV or Marine generator control).
Despite being built during the 1970's many remain in service in RV and Marine applications. Onan obsoleted this board in the early 1980's and now only offer a relay conversion which is costly to install.
It is built in the USA and backed by a 2-year Warranty.
