Hi.
The vast majority of the time(over 99%) it is the just the AVR or Capacitor failing (depending on which is fitted to your Generator. 2 or 4 wires = Capacitor and Brushless alternator, 5 or more wires = AVR and Brushed alternator.) Replacing this should fix your problem.
Only replace the part with a quality Grade "A" replacement that is built for your Generator. Anything else could cause damage to your Alternator, resulting in the Alternator needing to be replaced and this is a very expensive! (We only sell grade "A" products.)
You will need to pull the part out and have it on hand when you order. Once you have identified if it is an AVR or a Capacitor, look up and purchase your replacement parts on our website.

The Mitsubishi units have to be reset by turning off the indoor units by switching the remote or thermostat to off. Then turn off the breaker to the outside unit(s). After 30 seconds,turn on the breaker and then you can turn on the remote for cool. If no lights come on on the inside units, most likely you have blown a fuse soldered on the main PC board. At this point, call your technician. A goos tech will be able to wire in an in-line fuse holder so if it should happen again, you can easily replace the fuse. If you do see a light or two come on at the indoor unit but the outdoor unit does not start after 3 or 4 minutes, sounds like you will need to call a technician. Most likely you have a blown fuse on the main PC board of the outside unit. It is not an easy one to replace. Good Luck!
SOURCE: Generator runs, but does not generate electricity
Reset / tickled? There are resistors and diodes in the end of the alternators rotor (the bit in the middle that spins) If these look ok visually then change the capacitor which is a barrel shaped object usually with 4 prongs on the end. Without a capacitor the genset will not produce a voltage.
SOURCE: McCulloch fg6000mk: generator motor runs, no power.
You need to trace out the power wires the come out of the genset. They will end up on a breaker. With a volt meter measure both sides of the breaker. If one side has voltage and the other side doesn't, then your breaker is opened. Press the breaker in closed to see if it actually closes. If it don't then you will need a breaker. However, if no voltage is being produced, it is possible that the voltage regulator let go.
SOURCE: no output voltage at all
The generator needs to be 'flashed' to bring back the excitation for output. Is this something you can do? Let me know and I can help you...

I had this same issue with my NP 50G. I replaced the oil pressure & over heat sensor and fuel filter but the problem still existed.
After that I took the fuel bowel off the carb which had some dirt in it. Sprayed it with carb cleaner and that solved the issue. Hope this helps......
