This is a 5kw Round AVR Voltage Regulator

This is for a 5kw round style AVR Automatic Voltage Regulator and generator carbon brush. The voltage regulator in this kit is intended for use in generators with a 4kw to 10kw rating. These parts are universal type of parts that are used in many different brands and models of generators.

The AVR has a 4 blade large plastic plug connector and 2 single female connections for the carbon brush. Many different generators use this style of AVR but there are a few factors. Some brands and models use a different style for accessories such as a remote starter. All generators are either brush style or brushless. A brush style generator will use a carbon brush and a voltage regulator. Brushless style generator have no carbon brush and use a capacitor instead of an AVR. If you are not positive what you need it is always best to remove the AVR and compare before buying.

If your generator stops producing power the AVR is one of the most common issues. You may replace this voltage regulator and still not have power output or low output. This means you may have more than one issue. Please view the Additional Details tab on the left of the page and review our Repair Notes at the bottom for some helpful information. If you still do not have output feel free to contact us

We always suggest that you change your carbon brush at the same time as you change the voltage regulator. This style of carbon brush is used in hundreds of brands and models of generators. If you carbon brush looks similar to this one then it will work for your application regardless of make, model, or rating

Repair Notes

While it is often the case that replacing an AVR requires no more than installing the new part this is not always the case. Please review our repair notes below that cover common issues that may occur when replacing * Less than 120v Output – It is often the case that a new AVR will need to be adjusted for the unit it is being placed in as all units can produce slightly different. All of our AVR's are adjustable using the small brass screw in the small blue box on the back side of the AVR * No voltage after installation – There can be several reason as to why a generator will not show or produce voltage after a new AVR is installed. The most common issues are the + and -, positive and negative, wires connecting to the brush assembly being crossed, the 4 blade plug not making a good connection, an old carbon brush being bad or worn out, or the carbon brush connection area being dirty or corroded. There are several other reasons that your generator may not have output after installing a new AVR, including the head being bad. If you are having this issue check everything stated above and if you are still having that issue contact us for further assistance We always suggest when changing an AVR that you also change the carbon brush.
