No electrical output on yamaha

[Fresno_Tundra_D]

On my 10 year old yamaha 3000 with boost I have no electrical output. What would cause that? Do they have something like a voltage regulator that goes bad? Anybody have any experience with a gennie of any kind that stops sending out electricity. One thing of interest though is that when I plug in my cell phone charger with cell phone it gets electricity. When I plug in a hair dryer it works only on high speed but not on low speed. When I plug in a coffee maker I get nothing, not even the flashing "12:00". All thoughts and ideas are appreciated .

Putting out with light load and not with heavy load could indicate that the brushes are worn out or an open in the genset windings.

There are many things that can cause it to have no output.. Is this a traditional generator or an inverter model.. Will cover the list

Voltage regulator is on the list
Brushes on the alternator
Windings
Circuit breakers

WIRE CAME OFF TERMINAL

and if its an inverter model... the inverter.
That is a short list, there is also a longer one

BUT I do not know enough about your generator to go there.
