So checking with the multimeter there appears to be 240 at the larger dryer like plug, but none at the 120 outlets.
That's great news. (We were both replying at the same time, so I hadn't seen this for my previous post.)
For the household outlets, I'd check for AC voltage on all the different combinations of a given receptable. Like narrow-slot to wide-slot. Narrow-slot to ground (small round opening). And wide-slot to ground. See if you measure voltage on any of those. Do this for both of the 2 separate outlets, since they each have their own 20A circuit breaker. If you want, you can certainly check both of the receptacles within a given outlet.
But getting 220V is encouraging, so the generator is doing *something*. (Edit- and that means you don't need to do any more stuff with the drill. There *is* power, just not at the outlets you want) The issue then presumably lies with:
- the 110V outlets GFCI functions
- the wiring between the 220V and 110V outlets
- the 20A circuit breakers for the 110V outlets
Do you have voltage on the high-amperage (30A) 110V outlet, the one with 3 curved openings arranged in a circle? If so, for now, maybe you could buy an adapter to allow connecting normal household items to that type of receptacle (NEMA L5-30). If you could find that adapter locally, that could get you going for now.
You might also be able to buy an adapter go from the 220V receptacle (NEMA 14-50, an RV receptable) to a normal 110V style. For instance, this would give you access to both of the 110V outputs from the generator (giving you access to more power, since each 110V output has a limit on the output power), using the 220V output that *is* working:
It would be preferable to fix the issue, of course, but that cord should give you power, based on how the generator is functioning right now.
Depending on where you find voltage, it may come to removing the cover from the outlets panel and looking inside, to see if a wire is disconnected, for instance.
The manual for your machine seems to be this one, it shows a wiring diagram on page 25:
