FAILED YAMAHA EF1000IS <span class="highlight">GENERATOR</span>

Stevo - My long experience with machinery (nearly 45 yrs) tells me that if a particular model of machine blows up in one area, then all of the machines in that model blow up in the same area.
Just the same as particular vehicles have a fault in one part, all the vehicles you look at will have that same part failing, or failed.

I'd suggest you'll be waiting a long time to find a unit with a good genset end, and a blown motor.

I'd respectfully suggest the best and simplest course is to scrap the genset end and just sell the engine, and go buy another genset.
Little engines are always popular, they usually sell pretty rapidly.

Always remember that these complex little inverter gensets with a lot of electronics are very susceptible to dust - so ensure that when you position the unit for running, that it can't suck up dust via the cooling fan and distribute it through the electronics.

Cheers, Ron.

An electronic enthusiast may be able to look and see if the inverter is totalled or it only has a component problem. Many are sealed in gunk and non accessible though.

A friends son, works at a Yamaha dealership and he said no one ever repairs them.
He is aware of a few which have done the inverter.

The engine design is an integral unit with the alternator section and isn't an engine on its own for using by others. Perhaps for a capable person it may be interesting/useful but for the average person they wouldn't know how to use it as it isn't like a universal stationary engine.
PS in hot climates where the ambient temp is high a LARGE computer fan running of the 12v battery charge section and adding air to the case air intake will help the heat/cooling of internals.
I agree with the other comment, the heat coming out of them is like a heatgun.

Modern technology ! So disappointing to have to ditch a good unit - I'll bet you can find a corner in the shed for it :-o).... agree re the heat comments above - I had a vapour lock in my EF1000iS at one stage, while using it on a very hot day - it has to be placed in the shade, on a hard surface as mentioned to avoid dust pickup and I take the back cover off to aid cooling - the plug hatch on the top can come off too. The aux fan idea would be my next move if extra cooling was required. Mine is about 8/9 years old but has had little work. I hope yours did provide a lot of power for your initial $ outlay.

G`day stevo,
I have an almost identical story except that my genny was a Honda EU10i.
The motor still starts first pull and runs perfectly.
There is no electricity produced if it switched on after the motor is started.
HOWEVER if a device, e.g.an electric drill, is connected and switched on PRIOR to starting the motor, then the drill will run when the motor is started but not at full power.
If you turn off the drill it wont start again unless the motor is stopped and then started again while the drill is on.
I haven`t had the power output measured to determine what I could, or could not, use the genny for now.
Honda Australia didn`t want to tell me anything, just suggested that I take it to a Honda service business. The service/retailer tested it and said that the Inverter was stuffed and quoted $1300 + time to repair it. They also suggested that I should buy a new one.
So I did buy a new genny, a Yammaha EF2000 from a different place for $1750.

Scrubby.
