Get two short extension cords and cut the FEMALE end off each one. Strip back the insulation on that end. Connect the two green wires to each other, and connect the two white wires to each other.
Connect one black wire to a light switch, and connect the other black wire to a 20W appliance-type incandescent light bulb. Also run one short black wire (from a cut-off end) from the second terminal on the light bulb to the second terminal on the switch, like so:
plug -- black -- switch -- black -- bulb -- black -- plug
plug -- white ----------------------------------- white -- plug
plug -- green ---------------------------------- green -- plug
Turn the switch to the OFF position.
Start the generator. Plug one plug from your new rig into an outlet on the generator. Plug the other plug from your new rig into a wall outlet supplying 120V. With the generator running, turn the switch to the ON position.
The bulb should flash for a short while, then become steady. When it's steady, that side of the generator is flashed. Repeat for the other side of the generator if it makes 240V.
Do you have power at the outlets? If you do but the lights keep going dim then your converter is going bad or has already failed. Your lights are 12v and the outlets are 100v. If you do not have power at the outlets then you need to check the transfer switch that toggles between generator power and shore power.
These generators have a GFI outlet on them, and they do fail. I would suggest you check all output circuits and see if you have any output. If so, pull the GFI and see if it is getting power to the outlet. If so, replace the outlet.
Check the Ground Fault Indicator circuit breaker for triping, and look for the high limit on generator.
Reset the main breaker by triping it full right and then back.
Vitally
Most generators have several circuits incorporated within the windings. There are usually two 115v windings, one or two windings that produce power and sensing voltage for the regulator that supplies power to the armature (produces magnetic force) and sometimes a 12v winding to supply power to charge the battery. The two 115v windings power one 115v plug each and together power the 220v plug. Each outlet has a breaker and or ground fault. Since the 115v plugs are working indicates that the 220v plug must have an open/broken wire or faulty breaker. Easy to check, however you must open cover to wiring compartment and trace wires. Should be easy fix. You do not have to start engine to find broken wire. Use ohm meter instead. With engine off, Insert probes into 115v plug and obtain ohm reading. Then insert probes into second 115v plug and obtain similar reading. Look for same reading at the 220v plug (remember 2 circuits of 115v, ground and neutral). Good luck with your repair and email if you have other question.
It is possible that your voltage regulator is shot but before purchasing the volt regulator try flashing the fields first and make sure the brushes and rings are clean.
There was a day and time when generators were simple. There were no capacitors, regulators to control/adjust power to magnet or ground fault outlets. Winding getting hot indicates short, however could be bad capacitors. Rectifiers and capacitors must be removed from circuit to test properly. Here is a simple test that I use to find fault area. I use a small power supply (16v AC 1 amp like doorbell transformer) into the 110v outlet of generator. This should energize the armature magnet and actually produce voltage at commutator with brushes pulled off. You can slowly pull the starter rope to move the armature into a different positon the voltage will vary. If the ac windings are shorted there will be very little or no magnet. There is a seperate 110 v circuit at the 220v outlet to test (there are two 110v windings that make up the 220v outlet, one is also used for the 110v outlet). There is another winding that products voltage for the regulator that powers the magnet thru the brushes but I think that circuit is porbably working because of the heat in the windings. You might even have 110v power at the 220v outlet. As our parents told us over and over, be careful when working with electricity. Enjoy
