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.

SOURCE: I have a Generac portable generator 5000 watts, won't start!

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.

SOURCE: I have a 17kw generac generator that will run

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.

SOURCE: generator runs, but produces no power

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.

Good Luck,
Mike...

    Trying to find oil filter that can be found locally from car part supply store.


    take the old filter along to the spares shop and see if they can match it up
    I suspect that the same filter will fit both engines
    if you want to get technical, use a verniers to measure the thread hole diameter, a thread gauge to get the thread pitch, and the outside diameter of the oil seal
    by going to oil filters manufacturers on line and researching their catalogues you will find pages of filters with dimensions that will match you filter
    I would rather just go and buy a genuine filter from a mower shop or kohler dealer as there may be a generic filter already listed.

    No power output from my generac 5000 power plus.


    sounds like you need to "flash the field". This means you've lost you excitation voltage for the generator to produce electricity. In most cases you need to get a 9volt battery and connect it to 2 & 6 inside the generator. They are Blue & Red wires, but they are not the only blue & red ones there. The generator should be running and the battery should only be connected for about 5 seconds. This is very dangerous because of all the high voltage and democrats.

    20KW Guardian Generac does not produce 12 volts to run engine


    The problem is that the printed circuit board inside the generator draws a little current from the battery even when the generator is not running. Over the course of a few days this can make the battery weak enough to be unable to get recharged by the built in running charger which results in not enough power to run the electronic governor on the generator. Usually the spark plugs will work even with a fairly low battery.

    Most of the Generac generators come with a built in trickle charger that runs off of the transfer switch load terminals. If your built in charger isn't doing the job it's either broken or you have the wrong sort of battery installed in the generator.
