If this is an XL4000 I first check on the condition of the brushes and slip rings, then look at the voltage regulator.

Regards,

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.

Hello, I would not advise you to adjust the speed without a frequency meter. for 220 volt operation, you will have to use the twist - lock receptacles and not use the neutral in the receptacle. This means one of the generator's hot leads is going to be the neutral in your system. The frame of the generator may be connected to the neutral of the generator, so be careful so that you do not receive an electrical shock. The voltage is adjusted within the receptacle box. There might be a small hole on the right side of the receptacle box that you can insert a small blade screwdriver into to make the voltage adjustment. You do not need to change this much to change the voltage. Now, the frequency is adjusted by a self-locking nut located under the air cleaner right side, when facing the engine. There is a spring on this nut / bolt assembly. I think it is a 5/16 nutdriver or socket that you need for this. Turn counter clockwise 1/8 of a turn. This will slow down the generator to about 50 - 55 hz. This is okay if you are running at around 52 hz. As the generator loads, the rpm will drop down. A frequency meter would be great to use here, as a too low rpm could burn out electrical motors and other equipment that you are using.

    Hello, it sounds like either you have a voltage regulator failure, the rotating field coil is shorted or opened, or the exciter windings have failed. No easy answer because there are a number of issues here as you can see. Depending on how old the unit is you might have warranty. I would suggest you take it to a generac service center to have it checked out. I have 30 years experience with generac units. If it is a voltage regulator issue, (this can be expensive) you can get a jobber regulator. This link is for a good generic substitute. http://www.mcphersoncontrols.com/html/mcp_products/voltage_regulators/MTS63-4.html
    I have used this regulator on 4000 watt to 50 kw units successfully. If it is a winding, then to rewind the stator part of the generator is expensive and a new generator is cheaper.

    Hi Jake and welcome to FixYa. I am Kelly. Check both CB1 and CB 2 circuit breakers by pushing them to OFF and then back ON. Open the brush block access and then start the unit. You should read voltage at the brushes of 5 - 14 VDC on the terminals of the brushes. If you do not have 5 - 14 VDC at the brushes the probable suspect is the automatic voltage regulator (AVR). If you do have the correct voltages then with the unit OFF.... do a resistance check across the armature coil by reading resistance at the brush block terminals. You should read around 180 Ohms. It can be more or less resistance but for sure less than 500 Ohms. If you do NOT get a resistance reading remove the brush block assy and test the armature directly by reading across BOTH slip rings. You should get the resistance previously stated. If you have resistance then most likely there is a problem with the brushes. (Too short / broken carbon brush / missing spring or a defective terminal.) Without knowing the AVR output voltage and the armature resistance reading at this point it is difficult as to how to advise you to proceed. Let me know the values you obtain for AVR DC voltage at the brushes and actual ARMATURE resistance reading. Make sure you use R x 1000 on the meter. I am having thoughts of maybe a broken wire somewhere inside the control panel also.

    Thanks for choosing FixYa,
    Kelly

    Guardian generac 10kw model 5502 does not output correct voltage


    the instructions says the voltage regulator is automatic/digital. when you check the voltage is there any load on the generator? if applying load to the generator doesn't help, you can manually change the motor speed where the governor connects to the carborator, but it may change the frequency, but the regulator may fix it
