Wow, you've got an ugly problem. It sounds like you already know that you have to pretty much disassemble these little buggers down to the frame to see anything inside, so I'll say what to look for:

1 - Burned wires in the part of the generator that doesn't move. This is the bit that carries the current shorted out by the mud.

2 - Burned wires in the part that does move. This is the bit that makes the magnetism that makes the electricity. There are also some diodes and MOVs tucked into the end of the plastic insulator

You're likley better off getting some other generator, sorry.

SOURCE: yamaha 6500 watt diesel runs but usually shuts

First thing to monitor is the fuel solenoid power. See if it is the thing that goess away to cause shutdown.

Tracing this back there is only a few things that control this: The battery, the low oil shutdown switch, and the run switch, and associated wiring.

If I were to ventture a guess, I would put money on the low oil shutdown switch.

SOURCE: generator runs, but produces no power

If it's still under warranty take it back to the retailer and tell them it quit working - don't offer any other information.

If you must fix the E/G yourself - On the generator there's a cover on the back; take the cover off so that the back of the windings are exposed. You should see 4 to 6 diodes mounted to the rotor and stator...those diodes are most likely burned out because of temperature failure, due to overload. You have to take them out to isolate them...they should read .6 Ohms one way; reverse the leads and they slhould read about 1.2 Ohms. If there shorted you'll read 0 Ohms and open infinety.

Anyway, replace those diodes and you should re-establish your field winding voltage which develops you A/C output.

Good Luck,
Mike...

Hi,

Somewhere in the wiring you have a "hot" wire touching a ground wire... that is what is shorting out and tripping the breaker...
Finding the problem may mean that you will have to take everything aprt and recheck everything then with wn OHM meter...
You could check it first with the OHM meter also...
That may tell you if the problem is in the cord or the box...(generator interlock)

Double check also that you have the right wires to the correct prongs of the plug and/or outlet....

Is the plug for your generator a three prong or a four prong plug???
You may have to jumper the nuetral and the ground if you have a four prong plug and a three wire cord...

Bottm line is that you are shorting out and that is causing the problem...

When I plug in a tool, it runs fine, when I plug it into my house with the breakers all off, it blows the breakers on the generator? My Honda 2200 watt works fine this way?


I think there is overload .kindly measure ur load of consumption. Do not run the generator set with high load it can be cause of circuit breaker Tripp off .

How do I disconnect neutral bond on a dewalt generator


Please be careful, you need a neutral bond for the GFI outlets to work when you are using the generator as a mobile unit and grounding the generator with a ground rod or building. When you are merging with a building with a grounded system, simply remove the two neutral wires (White) at the generators internal terminals from the generator frame but keep them connected together and terminate connection.

Bonding on a generator questions


Q. If I was to keep the tie between ground and neutral in the generator during standby use, would I have to break the neutral tie coming into home from grid?



A. Never disconnect the neutral line as it enters your house. It is held very well at ground potential. Each transformer is grounded, and every home supplies ground as well. The neutral coming in is the reference to both live lines, and without it, anything connected to either live line could see up to 240VAC depending on what is across the other side. Install a proper transfer panel, and the neutral issue will be taken care of.

Q. Where would I ground the generator at this time in this situation?



A. The generator will be grounded through the extension cord plugging into the transfer panel. Your home should have one ground connection only, adding a ground rod at the generator could create other unwanted safety issues.

Q. At this time is it safe to run an extension cord off generator direct to power a drill for example?



A. Yes. The transfer panel will take care of any neutral and ground bonding issues, provided things are wired correctly.

Q. If I was to lift the neutral to ground in generator and tag generator as floating neutral, then would I leave neutral unbroken in service panel?



A. Yes. The common point for neutral and ground will be provided in the main electrical panel.

Q. Could I use the 15 amp outlets on generator safely in this position to run a drill outside? I see generators with floating neutral have a 15 amp duplex outlet on cabinet also. In this situation would I install a ground at the generator?



A. If you were connected to the house with the four conductor extension cord nothing else will be needed.

Q. If you have a floating neutral generator and use it in a stand alone mode, nothing to do with a home, do you place a ground rod down? What happens with the neutral and ground connections? What about a generator on a truck or trailer?



A. In stand alone use, you should connect to a ground rod. Neutral and ground should also be bonded in the generator. The easiest way to take care of this is with a dummy plug inserted into one of the duplex outlets or the twistlock outlet. Jumper ground and neutral in the plug. A generator on a truck or trailer will follow the same rules for neutral and ground bonding, ground rods, etc.

Q. If the generator is a grounded neutral type and you only run the two live lines to the house in an illegal back feed situation where main disconnect is off but neutral still connected will I have 120 volts available in house between each hot leg and the utility grid system neutral? Would someone get shocked if standing next to generator at that time and touched it creating a path from ground to the generator?



A. The only time I would consider backfeeding a house is if the main lines were torn down and laying on the ground. I did this once after Hurricane Juan caused a tree to tear the lines off a neighbors house. The lines were still connected at the pole and were live once commercial power was restored, but there was no possibility of the generator backfeeding to the street. It took almost two weeks before the power company could get them reconnected. We still turned off the main breaker and installed a padlock to prevent it from being turned back on. The house was totally isolated from the grid so I felt it safe to connect in this manner. The generator connected via a 20 amp two pole breaker in the main panel, and there was power available for everything in the house - well pump, electric stove, all lights, etc. Generator neutral was floating as described above. Power supply was limited, they were careful not to overload and trip the generator breaker.

Q. At the same time I went to a friends home and after killing the main breaker and all 240 breakers ran a 3 wire cord from the generator 240 volt outlet direct to his pump, now isolated from the house panel using both 120 volt lines and ground. I then ran a 12 gauge 20 amp extension cord from the generator duplex outlet to a double male pig tail and back fed a kitchen outlet so he could have lights in the house. 1/2 the house to be exact. This was also a grounded neutral generator but we didn't have a problem. I did however drive a ground rod at the generator.



A. I think you were lucky this time. Electricity can be potentially dangerous and can kill and burn if not used correctly. Double male plugs should never be used as invariably there is exposed 120V on one end. If you miswire one end you can send 120V onto the neutral. At best this will trip a circuit breaker, but not knowing what else is done, could easily create a lethal voltage on the chassis of certain equipment. It gets back to doing something properly or not doing it at all. Why run the risk of personal injury or death?

Sparking in power box when we use the generator and trips the braker


When you say "power box" do you mean the main breaker box in your house? Is the generator hooked up to the breaker that you say trips when the generator is on? There is a short somewhere. First check the generator. Is it running OK. In other words if you plug something into the generator receptacle directly, does it work? If the generator itself works properly, then check the wiring from the generator to the circuit breaker. DO NOT use the generator until the problem solved = safety first.

I have a Husky 3750 generator for HD. The breaker trips when anything but the smallest load is placed on it. Is this anything other than a bad breaker?


You should be able to run an electric kettle and a toaster from that generator without problem. I would say to have a look at the breaker first. This seems to be the obvious source of this fault.

Is the house dead??? Did you turn off the main breaker in the house?? It sounds like you are sending voltage to the generator.Do you have a switch that stops the power from going down the street from your generator?? 3700 watts is not a whole house genny, you need more like 6500. 5000 min, unless you are just running the fridge and the lights. Is your "plug" wired into the fusebox through a breaker or straight to the bars? You gotta check these things out.

You should start with checking all your breakers to be sure the breaker did not pop just half of your breaker. This is something you should do with all your breakers. When you do this you should shut down all your 220v breakers so you don't get bleed back through the system. Other than that you need to look for resets on the tub. The heater is a good place to start and don't forget the gfci's on the tub or in the bath or laundry room.
