Onan shuts off while driving/hot
Hi there, Having an annoying issue with my Onan 4000 gas generator that is only an issue while driving the motorhome. While stationary its perfect. So if the genset is running while driving down...

Years ago Onan Diesel Gensets had the same problem in Transit. They were mounted up front on Diesel Pushers and when in transit the design of the fresh air intake could NOT pull enough adequate air to keep the Genset from overheating. Onan's solution was simple. You installed the Onan lower air dam that stuck DOWN from the bottom of the genset in front and that allowed the Genset blower wheel to then pull up enough air. The Dam just stuck down about 3 inches. Maybe this is a similar problem and solution. I would be contacting your local Cummins/Onan service center. Doug
