Onan 4000w generator

My Onan GenSet operator's manual talks about clearing out the muffler of soot, Etc. I removed the 2 bolts in the bottom of the muffler as described and then started the generator. I was not able to get the generator to start the AC (1500 watts or there-a-bouts) in order to put a load on the generator, also as described. The AC works when outside 110-120 power is hooked up. What am I doing wrong?
  • That must be it. When I unplugged the external power, I didn't reconnect it in the box. I haven't tried it yet. Thanks from a newby to RVs.
  • Did you plug the Elec Cord back into the receptacle in the Electric bay? That is how the Generator puts 120 volt back into the RV to run the A/C
