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!!!!!!!!!!!

You need to determine if it is a Brushed or Brushless generator and follow the tests on the link below. (You will locate the brushes on the end of the alternator in a 12o'clock position if they are fitted).
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--
The generator should be attached to the gentran switch box then started. Once started, then follow instructions for that system to swich to generator power. Some setups may have their own initiating order, it is important to obtain the correct instructions from your manufacturer and keep them where you can find them in a hurry.
I hope you don't need it too often:)
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.
