If your generator cannot run normally, please follow the guide in this article to solve your problem.
If diesel generators fail to start, you can analyze the causes from fuel system failure, electric starting system failure, insufficient compression pressure in the cylinder and the low ambient temperature and other factors.

SOURCE: Generator stopped producing electricity

if the generator has been sitting for a while you might have to excite the magnets to start producing power. plug in a reversible drill and with the generator running turn the drill in the reverse direction by hand while holding the trigger in the forward position.

lights on motorcycles are not like scooters, they run off the battery. In the old days they had a separate switch, now they turn on immediately after ignition key is on.

Crafsman 2400 watt generator star ok but only run for 45 sec.& it won't star again the motor is a briggs & stratton 5.0hp


I have a Craftsman Snow Blower with a Briggs & Stratton Engine. I had the same problem. I searched online and read a little bit about this run and stop problem. One solution was to put something over a piece of metal that separates the hot engine part from the other part of the other side of the engine. I used a piece of heat resistant cloth from Lowes in the plumping area where the torches are. It fit and worked. Engine keeps running. I ran it for over an hour last spring prior to storing it.

Porter Cable BSI550 W 5,500 Watt Generator With 10 Hp Engine No AC output


Sounds like the generator unit (sometimes called the generator head) has overheated and melted the insulation in the windings. This is the same as an electric motor "burning out", and if this is the case, then the generator is toast. If you happened to notice that the lights or fans were getting dim or slowing down before the breaker tripped (without the gas engine slowing down) then this is most likely the case and you generator is toast. But if the output just suddenly quit, then it is possible that some smaller electrical component has failed. In any case, it's not something external that you can easily reset or replace. Sorry for the bad news.

The generator kicked the breaker of and was smoking and smelled like electrical


What type of load (electrical) was hooked up to this generation?? If the surge voltage and current was exceeded above the generator maximum for any length of time. There problems, it could be the regulator, insulation burnt off the windings.


I am taking a guess here. Now, 7100 Watts is it typical surge wattage. This mean that the generator will deliver 7100 Watt (voltage times current) this is know as the power factor. The actual operating load would be 6800 Watts and I would even operator the generator at its peak wattage. Something in the neighborhood of 10--15% less the peak wattage. Therefore a good positive theatrical Wattage would be 5800 to 6350 operating wattage. Then this generator would run all day.



Just remember Ohm's Law. Current plays a big factor in loading of a generator while the operation voltage is at 120 AC Volts. Example: electric motor; Now electric motor when starting will pull three time its operation current. Operating current for a 1/2 HP AC motor is 6 amperes but start this electric motor will require 18 amperes. This is one reason why they starting capacitors on smaller electric motors. Larger three phase electric motor can literal stop a generator cold...in its tracks. It put such a large demand on the generator it stops the engine powering the generator. I have seen crankshaft break because the generator could handle the heavy current load.



Remember, any time you are running a small gas powered generator. All ways figure what the load and surge current load will be before hooking up any generator. Normally this is figured in VA (volt/amps). Wish you lock. GB...stewbison

Honda ems 4000 generator starts and runs great, but no power


At the controller, you need to see if it is actually sending electricity out of the Generator/Alternator, have a look where the leads from the power making unit mates, (Think of it as a motor in reverse) onto the board. There should be an AC Voltage there, then, work back, or out from there, trace the Voltage until it stops, thats the problem... Check the Breaker isn't tripped or faulty too.

Honda EU30001 generator causes erratic pellet stove operation.


Ok Motors and the like generally DO NOT really go all that well from a generator, what load does the Stove use?, You must add up the cumlitive "Wattages" of ALL things connected, see your generator is about 3000 Watts, 3KW, How much "headroom" is there between the two? Whats supplied versus whats being used? Purely inductive loads, like Motors etc, are less responsive than electronic loads. I suspect that your generator is NOT providing enough current to the Stove, especially when "Other" things are connected. also. Look, if the, any, generator is 3000 Watts really you should only load it up to a couple of KW's, 2.5KW being about maximum. To do what you are doing would require, IMHO, at least, 5KW, to get the "Headroom" of current drawn over current able to be delivered by the generator. Also inductive loads loose heaps of power and actually cause a higher draw. So that your answer, you must use it well, inside it's rating, not right up to the limit.

5500 generator stopped producing eletric after


First check with the dealer and see if it is still under warranty. If it is not, make sure nothing is blocking the air flow around where the control modules are located. This could cause the voltage regulator and other electronic parts to overheat. Next check the brushes and make sure they are free of any dust or build up preventing them from making contact.

If everything is OK the next thing I would do is change the voltage regulator.
