Eeeeeeek! Thats not good! Sorta like a grinding sound? If it's under warranty take it in! Might be the "winding" where the electric is created.

low voltage can be from incorrect running rpms as it is new out of the box I suggest that you get a service under warranty to sort out any problems

This is an older generator. If you have the owners manual, there should be wiring schematics that give the wiring legends to all of the connections. I can't find a downloadable .pdf manual for your generator. If you don't have the manual, you'll likely have to take your generator to a service center for repair & testing.

Generac website should have it.

If you replaced starter and it does not crank at times, then perhaps the new starter has bad spot on commutator and when the motor comes to rest on one of those areas the brushes do not transmit power to the motor. Those rings should be squeaky clean. Then check for a bad or intermittent connection not allowing motor to get electricity. Next time it does not crank check to see if you have voltage at motor.
