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.
Despite being built during the 1970s, many remain in service in RV and Marine applications.
Features include improved componentry, heavy duty rocker switches and heavy conformal coating (to protect against corrosion - a major enemy of any RV or Marine generator control).
It is built in the USA and backed by a 2-year Warranty.
This board replaces the following ONAN part numbers: 300-C859, 300-0859
Onan obsoleted this board in the early 1980s and now only offer a relay conversion which is costly to install.
