I purchased this gernerator following Hurricane Katrina. We lost electrical power while Hurricane Gustav was visiting us and the Generator worked for a day and a half before it stopped generating electricity. It seemed to be losing generating power over that time period. Where and how do I begin to trouble shoot the problem?
I assume it is a hand start genset. The most common problem if it has been sat for a while is rust on the ignition timing flywheel. If you take the pullcord housing off (recoil) then you will see a big flywheel with what can only be described as a big forked prong with a couple of wires on it. This flywheel should be stainless steel and rusts when sat around for a while without use. Its job is to complete the circuit to the spark plug every time the flywheel passes the forked prong at a given spot on the flywheel, the faster the wheel turns the faster the spark hence the engine runs quicker. Clean the rust off with a releasing agent (wd 40) hey presto!!!!!!!!!!!

If the fuses are good, your AVR (Automatic Voltage Regulator) may have failed or (less likely) you may have lost the residual magnetic field in your armature. With the generator off and your circuit breakers closed, plug in a corded 120V drill into one of the household 120V outlets on the generator. Spin the drill's chuck quickly, by hand, several times; This introduces a small electric current to your armature, "field flashing" the generator. Start the generator and check if the generator is now producing voltage. Sometimes this works, sometimes it doesn't. If no voltage, then it's likely your AVR has failed. You can purchase these online at ebay for about $35.00-$50.00. Buy a couple of them; these AVRs have a high rate of failure.
Hello. W/D here. You've posed a fine question, as it has several answers. We used one of these during Hurricane Katrina. 1. At idle, you can expect about 6 hours. 2. Fully loaded, you can expect to refuel it at about 4 hours without the tank being empty.
Your actual time will vary with the demand placed on the generator, but these times are best as I recall. Hope that this was of some small help, --W/D--
Most likely the protective circuit breaker has tripped. It doesn't look like the circuit breakers in your house wiring panel -- it is often just a small button that you must press to reset. It can trip easily from a surge when you first plug in an appliance (especially one with a motor), but if it keeps tripping with nothing plugged in, then you have a short in the generator wiring. Good luck!
Check the following:
Exiting windings could have losts its 12volt exiting load. In that case it must be exited by 12 volt external battery
Another common problem is burned off wire or loose connection
Reset / tickled? There are resistors and diodes in the end of the alternators rotor (the bit in the middle that spins) If these look ok visually then change the capacitor which is a barrel shaped object usually with 4 prongs on the end. Without a capacitor the genset will not produce a voltage.
Dryers require a 40A circuit breaker to handle the current. According to Ohms Law: Watts = Volts * Amps. Therefore, you require a power capacity of 220V * 40A in order to safely run the dryer, which is 8800 Watts. This means your generator does not have enough capacity to run the dryer. If we consider the full power of your generator at 6500 Watts, this only allows for 29.5A, which is not enough to run your dryer.
If it WAS possible, you would need to ensure that you ran a 30A heavy extension cord with the correct 220V plugs and receptacles on the end. This would require at least 10gauge 3-conductor wire, which is quite expensive.
However, that point is moot, since your generator does not have the capacity to run your dryer. You could try it, but I rather suspect that the dryer will trip the 30A breaker on the genset circuit. If you do try it, make sure you run a 10-gauge, 30A extension cord or you could have a fire.
