SOURCE: no power output from a generac c5000 generator

First check the circuit breakers on the control/outlet panel.
Then take the end off the generator and look at the brushes (usually what breaks) and the 2 slip rings they ride on (these get dirty and have to be cleaned off with a bit of emery cloth)
Then look at the voltage regulator (the little board that the brushes plug into)

Let me know if you need more detailed help,

SOURCE: Honda EMS 4500 Generator - High Voltage Problem

As far as I can tell on the wiring diagram for this generator there is no voltage regulator unless it's incorporated with the auto throttle unit.
To lower the voltage you need to lower the speed of the generator engine. To do this there should be a screw on top of the engine under the tank when your facing the recoil. This screw presses on a arm that controls your governor. Turning it in (righty tighty) will increase rpms, turning it out will lower them. You should see the voltage change on the voltmeter.

SOURCE: 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

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: 10kw Generac Guardian not cranking, shows rpm sense loss

Sounds like Generator mode switch should be "ON".

Generac troubleshooting my generac 14kw generator engine runs why doesn*t it produce electricity

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.

Generac portable generator doesn't produce power

Remove front cover on the genset and you will see the brushes and rings. Clean the rings if black with emory cloth and inspect brushes. Flash the fields by apply a 12V battery to the brushes. the brush closest to you or the bearing is connected to the positive side of battery and the back brush is negative. You have to do this with genset running. You should notice your voltage climb up to over 50Vac maybe even over 100Vac. Make sure to use rubber gloves when flashing fields and keep hands away from rotating parts. if voltage does increase when flashing the the voltage regulator is shot. If voltage does not climb then you will need a new genset or generator end.

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.
