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 .

There are many things that can cause it to have no output.. Is this a traditional generator or an inverter model.. Will cover the listVoltage regulator is on the listBrushes on the alternatorWindingsCircuit breakersWIRE CAME OFF TERMINALand if its an inverter model... the inverter. That is a short list, there is also a longer oneBUT I do not know enough about your generator to go there.

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.

Thanks for the information thus far. It is an inverter type. It is the EF3000iSEB. Do any of you know how much to repair it if say it is the inverter itself or maybe the brushes? I'm trying to figure out if maybe it's time to start looking at new generators. This one has been trouble free until recently and now has about 160 hours on it which, to me, doesn't seem like a lot.

I was just told by a Yamaha service rep. that this unit has no brushes on the alternator. He said most likely it sounds like either the power and or control unit. He said it was one big unit that included the voltage regulator and stater/ windings etc. He told me the replacement unit is $1200-1300 and another 200+ in labor. Ouch! I only paid 1200 for the generator(with less then 1 hour on it) and got 10 years with it but I expected more then the 160 hours I got. Maybe it's time to start looking for a new one. So disappointing...

You may already have this manual.I would be looking at a replacement and not repair at the price you are quoted.Might look on ebay for parts, but what parts?Manual

Yeah thanks, It did come with that manual. The only help it provided was to show me the location of the one fuse the unit has by the battery. The fuse was fine.

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.
