Try flashing the rotor field. It may have lost its magnetism. Most standby generators will lose this if in long term storage.

If you don't know to do this have someone that does as you can damage your generator's alternator if done incorrectly.

Capacitors typically fail due to overloading and large current inrushes like HVAC motors compressors etc. Or shorted wiring / windings. Diode? Are you referring to diodes in the exciter? Often fail due to over current

putting out some voltage is a good sign i think you need to look at the voltage reulator

My generator runs but does not prouduce electricity


The basic cause is the rotating magnetic field has collapsed.

Causes of that can include blown rotating diodes, blown regulating capacitor, loss of magnetic remanence.

Search google for things to try. IF it is only loss of the small bit required magnetism, SOME have found plugging in an electric drill that DOES NOT have a throtle speed control and spining the drill with it switched on will create enough field to start the unit generating. Blown diodes or capacitor requires replacement of parts.

If the unit is a permanent magnet type (usually only small units) then there would be open circuit in the wiring or the rotor has somehow lost the magnetism.

SOME units have brushes to excite the field with a direct current. Loss of brush contact to the slip rings or the rectifier supplying the current will cause no output of the generator.

In your case, the Dewalt DG6000 is a brushless type. The most probable cause for the problem is the regulating capacitor. IF the unit has been overloaded or a short placed on it, then the rotating diode(s) have probably been shorted. Searching google you will find that there is a method using light bulbs in series from utility pwer to attempt recharging the rotor. This will ONLY work if the parts have not been damaged.

Timer


firstly check your sleeping timer set ups. if that is okey, then check the following
the power supply components eg
power transistor on the power supply lekage
zener diodes, power diodes of the bridge rectifier.
in short the supply is drowing to much current, hence semiconductors are heating up and reach a cutoff point, and saturates

Microwave does not heat


The high voltage circuit that supplies power to the magnetron may be separately fused inside. Unplug it, remove the back panel and look for a fuse clip. The high current fuses (20-30 amps) often have a white ceramic housing and are tubular. If you have a multimeter at home (you should, they are cheap) you can check the fuse after removing it from the holder.
The reason your other things are still working is that they have separate supplies; the one for the panel will supply only low voltages and not much current.
If you have a meter, check for a largish black plastic component often mounted on the floor of the case. This will be a diode or diode bridge and this can also fail.  A meter would let you check it if you have one.

No power output


Hi, check your exciter cap inside the control box as it probably is knackered, Replace it with a new one.
Or if the unit was severly overloaded the windings are probably fried.
