Question about Generac Guardian Ultra Source 15,000 Watt Portable Generator #04582

2 Answers

Generac NP 50G Stops after 2-30min.

I just bought a RV with a Generac NP50G with about 500hrs. It will run for 2min to 30min fine then shut down, work fine with load. Checked the overheat sensor and it is disconnected so not the issue. Though it might be fuel filter but it stops quickly like it loses spark (not sure that is true though and it is not seized from over heat). If I try to start it quickly when I hit the start button nothing happens but in about 30 seconds it will start right back up.
Any help would be greatly appreciated

    I replaced the fule filter, oil pressure sensor, and choke solinoid. And the issue is still exactly the same. Strats well then shuts down after a couple minuests or less. I am confident it is loss of spark, there is no "sputtering" it just shuts off.

    I also noticed that the previous owner tried to bypass the oil sensor as there is two wires to it, one chasis ground and one that goes back in the engine (I assume control board). Also the over heat sensor is disconected.

    I also noticed that the choke solinoid is always charged (choke open). It was hot out when first starting but still assume the choke would shut when first starting, is this normal?

    The problem ended up being a dirty fuel bowl in the carb. After cleaning it ran fine.

    I now have a seperate issue I will post though.

Check the oil sensor circuit. I know when I take out or short out the sensor ckt on mine, it'll keep on running. low oil isn't good for any motor.

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.

garbage oil, maybe it wouldn't hurt to have the valves checked and adjusted. black smoke means oil is getting past the rings or the valves more than its supposed to be. clean the plugs often too.

Generac NP 50G wont crank


Measure voltage drop across the far ends of the fuse wiring (should measure zero), as one of the wires or it's connection to either end of the fuse may be open. Check the battery negative grounding connection at the frame. If all ok, you may need to find a wiring diagram for the machine. Does this unit have a low-oil-level switch which will kill the engine if set?

On a generac pressure washer that works fine.


Oil level in pump and motor OK? Spark plug not fouled? Has it sat for a while - carb dirty? Running (loaded) throttle rpm not high enough?
