Replacement Circuit Board for Onan "Power Drawer" NH Series Gen Sets
It is built in the USA and backed by a 2-year Warranty.
Flight Systems part number 56-1073-00 is an improved, direct replacement for the main control board used in several models of Onan "Power Drawer" NH Series Gen Sets that were installed in the still popular GMC Motor Homes built during the 1970s.
Features include improved circuit and harness design, heavy duty relays, added ignition circuit voltage protection and heavy conformal coating (to protect against corrosion - a major enemy of any RV generator control).
This board also replaces the following ONAN part numbers: 300-1073, 300-4950, 300-B944
