There are 3 things that can cause no power at the outlets.
1. Brushes are worn (remove the end bell and the brush block. Inspect the brushes for uneven wear.
2. The AVR has failed. This is a very simple regulator consisting of 1 capacitor and a diode. Inspect the cap and diode for any obvious signs of damage. Most of the time the capacitor bulges or burns out.
3. The armature commutator is very dirty. Clean off with sand paper by rotating the engine with the spark plug removed holding the sand paper in one place until the armature commutator is a shiny copper color.

4...... There is a possibility fo wiring damage or stator winding damage but.... unless you were operating the unit under a heavy load for a long time.... I doubt the stator has failed.


I think your going to find either a bad set of brushes or a problem with the AVR. Most of the time the AVR can be repaired by just changing the capacitor.

Thanks for choosing FixYa,

Why don't you keep it open?

There should be a "full wave bridge" which consists of three diodes that converts DC to AC. Try your local alternator shop before taking it in to a certified repair center.

need a meter to diagnose and test circuit and wiring ---check breakers also

Check the wiring from the utility through to the autostart control.; make sure all connections are solid and the wire itself is in good condition. New wire is no guarantee, several times I've had wire with a break somewhere in the reel. A non-contact voltage detector may helpful; start at the controller end, go to the other end of the wire, and see where you lose the voltage detect. It will detect voltage up to the break if you can keep the detector close enough to the wire.

CALL GENERAC AND ASK THEM .

The manual does not specify a minimum voltage for the battery. It merely defers to battery manufacturer specifications.

Measure the battery voltage with a DMM. A fully charged battery will be 12.5 to 12.7 volts. Any reading less than 12.25 will likely be problematic for the generator system. Remove battery and have it load tested or replace with a known good or new battery.
