How to test your Electricity Generator's AVR, Brushes and Alternator on a Brushed Alternator

When your electricity Generator stops producing power or fluctuates, you need to know how to test the Alternator to find what has failed. This video will show you how to do this. Send us your results, and we can tell you which part you need. Contact us via our website generatorguru.com/ask-the-guru/
**If your generator has a Brushless Alternator with a Capacitor, please ignore the Brushes step of the testing."
This test was invented by our Founder and is called "The Beagley Testing Technique." With this test you can find out what has failed in the alternator. By default you can discount faults in the alternator allowing you to determine if the AVR or Capacitor has failed. Normally you need an expensive tool to test AVRs and Capacitors at such a high voltage. With this testing technique you can do this with a standard multi-metre!
If you have any questions please email us through your local Generator Guru website.
We are always happy to help. We also sell 1,000,000 generator parts and pro tools on our website with quick shipping.

We thank you for your interest in our help videos. Unfortunately, due to limitations in KZfaqs comment sections, we are unable to quickly answer questions in the comments. Please feel free to contact us directly here: www.generatorguru.com/need-help/ PLEASE NOTE: You cannot test the AVR without a very expensive piece of kit called a Megga meter. This is why you need to do these tests to make sure there is no other problems in the Alternator. This will discount any other problems leaving the only possibility being the AVR.

you need to show,or tell,what happens when certain items blow. . my geni reved up. trying to find out why. the shop said,its chinese,buy another. there not interested. its remote start,key,pull,3.500 w. inverter. i have an old subaru,10 yrs,still going,but noisy as hell. 5kva. need a more portable geni. so bought the inverter.small suitcase size.

I have never commented on any of the hundreds (if not thousands) of KZfaq videos I've watched, but I am beyond grateful for this. I promised a client of mine that I would fix his generator, which I've never done before. More than 5 hours and many YT videos later, I still hadn't figured out the issue. The brushes were shot, everything else had continuity. Replaced the brushes, but still no power. You are the ONLY person I found that pointed out that the positive wire always goes on the left side of the brushes. I just hooked them up how they were before (another shop tried to repair). All of a sudden, IT WORKED!!! So, thank you so much for your help. Very grateful for you.

Hi Dale Thank you for the comment, I would love to hear more about it, a lot of people get stuck with the lesser known or unbranded generators as many rewind companies do not want to touch them so charge high prices for repairs to push people away and many people find themselves with a unit that is no use to anyone but not worth the repair costs

This has been the best instructional video I have found on you tube. Thank you for taking the time to demonstrate the testing. Now I have a question not really covered. I have 4.7 v to both the R1R2 and L1 L2 and 0v on R1L1 but I only am getting 1.7v across the brushes. The surface that the brushes are riding on are smooth. I thought these were grooved. I am looking forward to your expertise on this. Gary

@Generatorguru 7 жыл бұрын

Thanks for the feedback! R1 and L1 should be 0 vac if you have a voltage changeover switch and set it to the lowest setting. These results indicate you need a new AVR. The AVR should bring up the rotor to 5vac also if you run it for 20 mins without load to stabilize the magnetic field. Your brushes will be smooth where they connect to the rotor, but be sure they have enough play in them to make a good connection. If you are still having any trouble please let us know and we will be happy to advise you further. :)

@garyrancilio7184 7 жыл бұрын

Sorry I should have added that I have already replaced the AVR. This unit has only been used a short time. brushes are not even worn in yet.So are you saying I should run it 20 minutes with the new AVR? one last question. This John Deere 6200 watt runs wide open all the time. Is that normal?

The diodes on your rotor have blown. Check to see if they are accessible (usually on the end of the rotor or the fan end) if so replace them. If they are "in" the rotor you can take the rotor and windings to your local "motor rewind" company and they can rebuild it for you. But worth calling g a few companies as price varies greatly!

Very good demo. Nice, clear explanation. I thought I might mention though - that the rotor is not "otherwise known as the stator". The part you call "the windings" are the stationary part of the generator - the stator. The rotating part of a generator or a motor is the rotor - whether it has windings, permanent magnets or a squirrel cage structure.

Does it have 2 poles on the windings (i.e. L1 and L2 And R1 and R2). If so then one of your windings sound like they have broken. Test the continuity on each set to see if one has snapped.

I had a loose terminal on a new duromax 8500 which fried the avr.. They sent a new one but it was only putting out 109 volts on both sides . The avr had an small adjusting screw and I turned it and adjusted it to 120 . Works perfect now.. Thanks for the video

@Generatorguru Жыл бұрын

Ummmm.... you should not be adjusting that screw! They are set at the factory and now you have just changed the hertz output!!! That is not good!!!!! IF IT HAD CORRECT VOLTAGE BEFORE THE AVR BLEW - Run the test in this video and follow relevant steps below. IF GENERATOR IS COMPLETELY BRAND NEW: Best to set it back to 109 then adjust the speed by the top screw on the carb. Use voltmeter to set to the correct voltage. Before you do that. be sure good fuel flow is coming from the tank as the Petcock has a filter behind it which might be blocked. IF GENERATOR HAS RUN FOR MORE THAN 1 HOUR: If you were getting low power and it is NOT totally brand new, but has some running time on it, this is what you need to check: 1) it needs servicing. (1st service best done at 50 hours as loads of metal shaving are produced as it settles in) - see kzfaq.info/get/bejne/n9Vxmqaitc65lps.html 2) The engine has settled in and valves need resetting. This needs doing after about 1st 50 hours - see valve setting on our website and follow this video: kzfaq.info/get/bejne/o7-il9GBu9PFdKc.html If you need more help please contact us on generatorguru.com/need-help/ and we can assign you an engineer. :)

It could be that the floater in the carb is stuck. I suggest a good clean, and inspection of the whole carb. If there is old or dirty fuel it will allow to much fuel through to the engine. The only other thing it will be is a governor problem, but this is very rare.

Probably 1 of the most helpful and easy to understand videos I've seen. Especially as I'm trying to diagnose my genny which has stopped producing power. I've tried the drill technique and I've tried the flash with a battery after disconnecting the avr. Neither have worked. Tho the genny did produce power for the few seconds I flashed it with the battery. So now I'm wondering if the avr is fried as we noticed water in the extension lead that was plugged into it. So I'm thinking that has sorted out the avr to protect the alternator like you just mentioned it should!

@engineeringdept.generatorg1760 4 жыл бұрын

As your results are showing a low voltage, we suggest you “Flash” your alternator. Follow the steps below: 1. To re-excite your alternator, we suggest you only use this method, as described by Generac Generators on KZfaq: kzfaq.info/get/bejne/Y7KCaZWk0p25g4k.html 2. Run the generator for 20 minutes without load to stabilize the magnetic field in the Alternator. 3. Test with a suitable appliance to make sure the load is stable. If not go to step 4. 4. Repeat our tests: www.generatorguru.com/help-me-fix-my-generator-repair-advice/ If results are below 1 Vac, repeat step 1. If this continues please contact us. If results are between 1-7 Vac, but you are not getting full voltage at the sockets, then you will need to replace your AVR/Capacitor. If results are above 8-10 Vac range, then you will need to replace your AVR/Capacitor. But be warned that the high reading will damage the AVR/Capacitor over time. This could result in it lasting a fraction of the time expected on a stable alternator. If results are above 10 Vac range, be sure you removed the AVR/Capacitor before testing. If you have and are receiving this result, we suggest you take your generator to a “Motor Rewind” company for repair. You can find your local Motor Rewinding company by doing a search on the internet for “Motor Rewind.” It is worth asking for a quote from a few Motor Rewind companies as their prices can vary greatly.

No the L1 & R1 reading tells me the windings are arcing. Remove the winding and have a look to see if anything has got ground up between the long fins. If so remove carefully and reassemble.

If this is not what has happened take the winding and the rotor to your local motor rewind company to be rewound. Hope this helps! If you need any more help call us. Our website lists our number. :)
