I recently bought a 1989 Sun Clipper (Gulf Stream). For the past 5 years it was being used as a camper (stationary) at a local river RV park. One of the issues with my new purchase was the generator (Onan 4KW). It would crank, run a minute or two and shut down. I read everything I could find on this site and a few others. Long story short, I contacted Flight Systems. I will say, they are a very friendly and helpful group.
Not having the tools or knowledge to trouble shot the system, and running out of time, I ordered their control panel (125.00). Installed it, same problem. So next I ordered the Voltage Regulator (200.00) again from Flight Systems. Bingo,
generator is running fine.
Another thing I liked about Flight System, I was told I could return the control panel for a refund (less a 25.00 return fee). This is the only place I have ever seen that will allow a return on electrical parts.
Now, if I can just talk myself into replacing the air bags
