We manufacture improved replacements for Onan Generator Parts, ranging from older items such as the "Power Drawer" Controller found in 1970 GM motor homes to the regulator for today's popular Emerald and Microlite Series Gen Sets. Our designs feature improved components, heavy duty connectors/terminals, and conformal coating to protect against corrosion.
All Flight Systems replacement Onan generator parts are designed to meet or exceed OEM specifications. We combine over 25 years experience in Generator Controls with our reverse-engineering capabilities to identify and eliminate the common problems found in many original circuit board designs.
