For the over voltage there is an adjustment on the control board.
Should be tested with a load something plugged in.
The hertz might just come on when under load and adjusted too.
If you need more give a model number and whether it is 13kw or 40kw.

Testimonial: "I see an adjust ment on the votage regulator but I didnt know what voltage to set it to ,I read somewhere that the Hertz needed to be adjusted first then the voltage, the model is a 004748-0 ser is 3655247,you say its high ,would high votage couse a starter to engage after running already"

SOURCE: Bought new XP8000e

Most people don't buy a transfer switch because they cost almost as much as the generator. Lowe's sells a very inexpensive one that will work for most people. It is made by GE and costs $92. Lowe's Item #: 42210 Model: TM860S. Good for 60 amps and 8 circuits. It takes standard GE half size breakers but includes the 60 amp main breakers (which are also standard but make use of a novel device that ensures you can't send power back up the pole). It's a great little design and if a breaker ever fails, you can get a replacement at Lowe's or Home Depot.

SOURCE: 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.

SOURCE: my standby generator is just cranking but wont turn all the way

If it was installed only five months ago, it should still be under warranty. Call Home Depot and have them send out a repair person.

I have a 20kw generac standby generator, where the starter tries to engage after the generator starts up and is running. Only has 316 running hours. Installed new starter in 2016.


The starter pinion drive gear is sticking.... its the smaller gear on the shaft that moves up and down to engage the flywheel gear and start the motor. Carefully put a LITTLE hi temp grease on the shift splines (curved ones) and see how much that helps. The gear is not staying "retracted"..if this doesn't help.. the spring that pushes the gear back down may not be strong enough...(you could always fix both)

What kind of oil do you use


Judy, Generac portable generator oil recommendations. Above 40°F, use SAE 30. Below 40°F and down to 10°F, use 10W-30. Below 10°F, use synthetic 5W-30. Oil should be changed after the first 8 hours of operation and every 200 hours of run time thereafter.
Check the attached links,instruction and guides, Good luck

I purchased a generac 22 kw 3 phase 120/240 volt generator. I was surprised to find that it had a wild leg. Can i change the leads on the stator output to eliminate the high leg and get straight 120/208...


This unit is wired 120-240V 3 phase Delta. if you are using on it 120/208V 3 phase application it will need to be re-tapped. If you are using it in a home 120-240V single phase it will need re-tapping, Do NOT just use 2 legs, as this will cause rotor imbalance and wear out the rotor bearings, and odd ball currents to flow. If there are 12 leads coming off the stator it can be reconnected. If not you are stuck with it, except by using a transformer

Under voltage alarm /shutdown on generac 10 kw gen.


The brushes on Generac automatic units are most likely not lined up with the slip rings and will wear down and burn out very fast. There is no way of checking this during assenbly because they are hidden from view and the generator has to be dismantled to be able to replace them. It's an extremely poor design and Genrac should face a class action lawsuit for producing this piece of junk.

A new Generac Centurion 36kW unit is producing 350 volts across phase A & B and 175 volts from each phase to nuetral/ground. I need 120/240 volts.


Hello, seeing how this is a new generator, I would have the company either replace the unit or have a certified tech (factory) set the voltage. My first check would be that the voltage regulator is not functioning, or is set incorrectly. I have worked on generac for 30 years. My suggestions are because of warranty issues. You might void your warranty if you try to set the voltage. Just curious, when you discovered this, was there a load connected? Also, I would make sure by checking line voltage with my multimeter to verify it is functioning properly. Sometimes a Digital Meter can give false readings. Do not put a load on the generator, I would connect a 100w light bulb to a phase - neutral connection as not to damage household equipment. Please feel free to contact again if there are more questions.

How to start a gas generator (should the choke be in or out, to the right or the left before starting


Most Generac generators have a lever for the choke that pulls out. So if the generator is being started for the first use or cold you should choke when starting . Let it run for 30-45 sec. then push it in . Once the engine has been run or warm you dont need to choke every time when starting .

Generac EPS-15 attempts to engage the starter while running


I work on these everyday. You most likely have a bad rotor or stater if the starter engages while running and no output. The no out put is making the generator think its not running causing it to try and start. If its not that then its the control board or voltage regulator.

Generator will not start


Is the oil sump full? Has it been run with out oil? You can do an amp draw test on the starter. Should be 60 amps or so. Can you roll the engine by hand? If engine turns free pull the starter out and bench test it with jumper cables. Positive cable to cable lug and negative cable on the starter case. Hang on to it, lots of torque. If the stater turns slow or gets hot it is probably bad.
