Yamaha EF2400IS Questions

SUE8mo

I HAVE AN EF2400iS. Our son used it 3 years ago when in the Tasmanian wilderness. It's always worked well. And we drained the fuel. We now intend to sell it as we're off-grid. It's been sitting idle since. What can we do to ensure it works correctly for the new owner? Or, do we advertise it as such, cheaply and make sure someone who knows what they are doing can make sure it performs well.

Hello

I have a EF 2400 IS which has been in storage for a few years, fuel was drained etc and oil was new when stored. Pulled it out 2 months ago, it started first pull as usual and runs OK at idle, but when subjected to a constant load it surges continually.

Can anyone help with a suggested fix or cure, etc.

Thanks in advance

Bob Murray.

Control unit

just the to s.3y

Hi my generator worked fine one weekend ran it to my van easily ran microwave toaster etc. Today i pluged into my van went to use toaster and the overload light came on so i then plugged the toaster directly to generator and it worked fine.

These are rubbish, first time having to do some hard work now it's only good for a boat anchor. Parts are just to dear to fix. Control modules are rubbish and expensive

Robert R.3y

I would like to know why Yamaha has superseded the control module on the 2400 model was it because the unit was faulty as they have one in stock but it is marked not for sale and have to order a unit under a different part number and this is the problem of a number of 2400 generator owners

I would like to know why the price of replacement parts are so expensive. Just had the control unit died in mine & the cost just for the part is $1268 - why when I can buy a new one for $1510. I've just ordered a new honda and will put my 2nd yamaha up for sale before it dies to. Just stupid pricing.

Hi I have a yamaha EF2400 generator for my caravan. Does it need a MEN link or is there one built in thanks Geoff

Craig 4y

My 2400 blew the control module. Waiting on parts to drop in price or buy a second hand Yamaha to cannibalise. Most people are concerned about personal electrocution protection when using portable generators or inverters powering their vans. There is so much information out there that it creates brain for. My suggestion is look up external link . In the mean time only use one class 1 appliance at a time.

Does turning the EF2400is upside down to drain fuel and retrieve an item accidentally dropped into fuel tank do any permanent damage ? It has fresh fuel , oil and new spark plug but won't run . Has started but stops after a few seconds.

Jaydon 5y

Did you find out? I just dropped something small in the tank and cant get it out and am hesitating to turn it upside down.

Richie L 5y

Never heard from any1 until now . Probably over 12 months since I posted it . I gave up on mine for now as we moved house cupla times . I spoke to a lawn mowers mechanic, said it would just be oil blocking carby , he reckons all he does to 4 strokes is carry cleaner until they run . How small is the thing you dropped in ?

Michael L. 3y

Just drain the oil and then turn it upside down . Dont leave it upside down for long an hour or so should be fine . When you have retrieved the item just let the generator sit in its upright position for a few hours , refill the oil and fuel and all should be good.

My Stator has gone on my EF2400IS. I need to buy the part but from what i can se they are way to expensive. Do i have to buy genuine?

Richard 6y

Mine went as well Ian and I ended up buying a new generator (same one). mine was 8 years old so for $1900 I just started again with a new one. What is the price to repair yours with genuine parts?

Roz T7y

Would this generator be a good back up generator to an off grid solar system? Can it be wired in for automatic start? Does it have an RCD?

Rob B 7y

Roz, the Yamaha is2400 does not have electric start. It's a very reliable pull cord start. And it does not have an inbuilt RCD as far as I know. As a camping/caravan power unit, the RCD is inside the caravan. It would certainly make a good backup to a solar/battery off grid system. On a 48v system it could power a 40 amp 48v charger.

Roz T 7y

Thanks Rob What about using it for charging batteries and using for powertools whilst building a house in a remote location? Will this sort of use damage the generator?

Penny7y

I would like to use it for back up heating in power outages in a small bungalow. Can you recommend a simple heater it could power?

Rob B 7y

The Yamaha 2400is is rated at 2200watts continuous, so any heater of less than this rating would be ok. Look st the power rating in the box or the heater itself. There are a number of small inexpensive two stage ceramic fan heaters available which are around 800/1600, or 1000/2000 watts which will work well with this generator. Any oil column heater rated below 2200 watts would be ok too. Small reverse cycle air conditioners of around 3000watts heating capacity (less than around 1600 watts power usage) will probably work ok too. I say probably there as reverse cycle AC units have motors which have a surge current when the compressor cycles on, which must be less than the 2400 watt surge limit of the 2400is generator. "Soft start" AC units reduce this surge on start up - talk to the people selling ACs if considering this option.

Penny 7y

Thank you very much ......I thought as much but good to have it confirmed! Penny

Will the Yamaha 2400 investor genset run my Heron 3 airconditioner? Regards Mr Pieter Lips

Ric 7y

Research says yes easily even with a 2000. My experience doesn’t cover caravan A/Cs. The Yamaha 2400 will run a whole house lighting system, ceiling fans, media and refrigeration. On top of that it won’t run any of our A/Cs, stoves or toasters. Providing the refrigerator is not on a compressor cycle it will even run a microwave if set at a lower power rating. In power blackouts we live very comfortably.

Rob B 7y

Pieter, it should run the Heron 3 no problems. It runs my 10 year old roof mounted Ibis air conditioner, PLUS a 300watt caravan washing machine at the same time. Together they make quite a big load, since that Ibis has no soft - start technology like some more modern AC units, and the washing machine puts a surge load on the generator each time the motor reverses direction (constantly). The oversized 171cc engine has plenty of torque to overcome short surge loads that can defeat smaller engined units. My sister has a fire fighting water pump on her farm which uses the same Yamaha engine (called an MZ175 for that use). It needs to start easily, and it does. It powers a water pump with a couple of 1 inch (25mm) fire hoses.

I would like to know why my Yamaha 2400is gen keeps hunting instead of running smoothly?

what are you powering up is the first q. next thing is make sure what ever you are running is turned to max other wise the items you are powering may be cutting in and out instead of continuously running, this may be your problem. hope this helps ron webb

donna 10y

My 1kva Honda Inverter gene would hunt with a 'cheap' battery charger... needless to say, it died after 3 years and the place I bought it from said the 4 year warranty didn't cover 'use' of the generator. I bought a Yamaha and CTEK battery charger and all is well. Hunting will wear the generator prematurely.

James 10y

The answer is to take the air cleaner and little bracket off , drain fuel out of carny by a little screw with Spring behind , out , let fuel out , put screw back in , start motor , then have a tin of good carby cleaner , spray with nossle on It , into carby and onto outlets until you hear the motor run smooth , put the air cleaner back on and you won't have anymore issues with it until the dirty fuel gums it up again , so keep the carby cleaner nearby .
