- Check the voltage from the input pin to the ground.
- Test the voltage going into the voltage regulator. Take your multimeter and insert it in the DC voltage setting.
- Take the probes and insert the positive on the input of the AVR and the negative on the ground pin.
- The AVR is receiving enough voltage to regulate down if you see a higher voltage reading.
- If the regulator is rated to the output of 5V, you should read a voltage close to 5V coming out from the output.
- To measure the output voltage, put your multimeter set in the DC voltage and place the positive probe on the output pin of the AVR. ...
- You should now read a voltage at or about the rated voltage the AVR is designed for.
How to test the AVR on an AC generator?
You can do a simple test with the AVR still mounted on the AC generator. Wind the voltage trim pot up and down and see what happens to the AC generator output. You can also bench test any AVR with a variable output Autotransformer (variac) and some test load that represents the AC generator field resistance.
How do you test an AVR with a multimeter?

How to tell if your AVR is bad?
Here are the steps you need to take to determine if your AVR is okay or not. Check the voltage from the input pin to the ground. Test the voltage going into the voltage regulator. Take your multimeter and insert it in the DC voltage setting. Take the probes and insert the positive on the input of the AVR and the negative on the ground pin.

- Manufacturer's Reputation. ...
- Visual Checking.
What is an Automatic Voltage Regulator (AVR)?
An AVR is utilized to control the voltage, as briefly stated earlier. It takes the fluctuating voltage and converts them into a stable voltage. The surge in the voltage typically happens because of the changes in load on the supply system.
When Should You Check Your AVR?
There are common signs that will tell you if your AVR needs immediate testing. Some of the common signs are the following:
Practical Steps on Testing Your AVR with a Multimeter
You know firsthand that a malfunctioning AVR could cause permanent damage to your generator. That’s especially true if you didn’t sort it out as soon as possible. Here are the steps you need to take to determine if your AVR is okay or not.
Final Thoughts
Excessive changes in the electricity levels coursing through your home might take place at any time. That could harm many of your electrical devices, obliging you to pay costly charges for its repairs. To make things worse, such surges could also cause short circuits, which could cause a fire in your property.
