Briggs Elite series, 8000 watt, 13000 starting watt, onlt 3years old, recently pulled from shed for use and it is not putting out any voltage, cranks and runs fine, there is a drop from the step on my shed and it could have jarred a little getting it out, was working fine. I tried resets and also turning power switch on and off several times.

I posted an answer that should help here.

SOURCE: High voltage low cycles

I worked at a tool rental center while going to college and learned how to service generators. Most appliances/tools require 50 to 60 cycles at 110 to 120 v. Your engine was designed to give maximum horsepower at 3600 rpm. Adjust the engine speed to produce 60 cycles and the engine should be at 3600 rpm and producing around 120v max. (Some special generators were designed to produce 230v 180 cycles, check manual) If your generator incorporates capacitors check them for at least 95% of printed uf value. They should be removed from circuit for testing. If there are two caps and one is weak make sure the new cap reads close to value of remaining cap. Finally there is usually a voltage regulator that varies the power to the armature magnet trying to maintain steady voltage depending on amp draw and engine condition. This regulator has no adjustment and is pass or fail type of item. Good luck, enjoy

Does it appear to be running as fast as it always did, as in RPM's are same as usual? If there is a fuel problem and rpm's decrease due to that, voltage will drop as well. Other causes may be internal problems with generator circuits etc, and will need technician to troubleshoot it properly.
You can try increasing the throttle manually and see if voltage comes up.

Voltage is adjusted by increasing rpm of engine. Use meter with Hz setting and try to adjust to 60 cycles and check voltage to be at about 115-120. If engine is turning 3600rpm/60 cycles and voltage is very low, then problem is most likely with brushes/ commutator rings, or voltage regulator. Some voltage regulators have an adjustment screw to bring voltage up/down (adjust to proper rpm/cycles first). Good luck
