Try putting 12 volts across the commutator at the brushes. Ust a low current battery nor a car storage battery.

Good luck,

Marty

SOURCE: generac model # 09734-1 no voltage output. would like a manual

Flash the fields. Remove front cover from the generator end. You will see the brushes and rings on the rotor. The ring closest to you is positive and the ring closest to the rotor windings is negative. With a 12 volt batttery and the generator running, place the positive side of the battery to the ring towards you and negative to the back ring. Make sure to use jumpers and keep fingers away from rotating parts and don't get zapped. You should see output voltage increase. If it does, your voltage regulator is bad, if it doesn't your generator end is bad.

Generac guardian rv generator starts and runs but after a couple minutes the power stops.....generator still runs??
Usually the generator will shut down if the ac is not present coming out of the generator. You stated that it still runs but no power on the output. Check your breakers first to make sure they are working properly. Depending on what board you have you can check to see if ac is present getting back to the board as well. If your board does not have this then they are using the frequency as a safety disconnect feature. That would lead you back to the regulator or loose connection or..dirty slip rings if this unit has brushes.

Generac generator manual
Usually generators that have stood for a very long time loose the magnetism in the ignitor coil magnet. With care, if you can find the low voltage wire into the generator 'motor' you can apply a 9v battery briefly to it and spark it into life. Use the generator if you get it generating, for a good period and don't leave it unused for a long while.
*IF YOU DONT KNOW AND UNDERSTAND ELECTRICITY DO NOT TRY THIS. GENERATORS CAN KILL*

Generac EPS-15 attempts to engage the starter while running
I work on these everyday. You most likely have a bad rotor or stater if the starter engages while running and no output. The no out put is making the generator think its not running causing it to try and start. If its not that then its the control board or voltage regulator.

No voltage output
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.
