The problem I am having is that It's not. I turned off all the breakers except the main and the AC and still nothing. Am I doing something wrong or does the generator just not have the juice?
Altitude matters. How high were you when you attempted to start the Coleman Mach3? If I recall gas engine loses 3% output per 1k feet. So at 5k ft you are only operating at 85% capability.
There are others who know these technical facts much better than I, hopefully they can clarify if I am incorrect.
Also is you Coleman Mach 3 a 13,500 or 15,000 AC? The Yamaha documention specifically refers to 13,500 high efficency air conditioners.
