Question about Electrical Supplies
Assuming the generator circuit breaker is on, depending on the model it could be the voltage regulator or the slip ring brushes or both. If it's a portable it could be a capacitor problem.

I am assuming the generator worked fine before the oil change. Now that you have done the oil change the genset does not start. These generators have a safety switch, which is basically an oil pressure switch that keeps the engine from running when there is not enough oil in the engine. Make sure that there is enough oil and if there is, look for a wire that runs along side of the engine to a round component. disconnect that wire and try starting. If it does not start then try to ground out the wire to the engine block. If this does not work, then there is other engine problems.

I have the 18KW model and was told that most alarms relate to a low battery. Make sure the battery charger in the Transfer Switch is properly feeding the battery or hook up a mobil battery charger to the battery and see if the alarm goes away. Good Luck.

If it's still under warranty take it back to the retailer and tell them it quit working - don't offer any other information.
If you must fix the E/G yourself - On the generator there's a cover on the back; take the cover off so that the back of the windings are exposed. You should see 4 to 6 diodes mounted to the rotor and stator...those diodes are most likely burned out because of temperature failure, due to overload. You have to take them out to isolate them...they should read .6 Ohms one way; reverse the leads and they slhould read about 1.2 Ohms. If there shorted you'll read 0 Ohms and open infinety.
Anyway, replace those diodes and you should re-establish your field winding voltage which develops you A/C output.
