Onan 7000 Generator problems

Rich Biebel · 08-06-2014, 10:48 PM

Here is a little tip that I thought of today....

Has only happened a couple times but...

The mufflers on some Onan's can get plugged up with carbon and soot...

Back pressure goes up and the engine does not run well once it runs for a while....

I disconnected the muffler from the exhaust pipe from the engine and engine runs fine.

This occured during a load bank test and would not be readily apparent without testing it this way....

Another piece of info I am just throwing out there ....
