Great video as always. This a great for a quick diagnose of a broken or not broken motor. However for intermittent issues under load I suggest carrying out the test over a longer period of time ( that would require other test equipment). Anyway great as always, take it easy and stay safe!
What about in a dual voltage 3 phase motor? You should show how you megga the windings to ground and to the opposite end of the windings. But good video ty!
To tell you the truth this is a waste of time and $ for generic units and let me tell you why: On a 3 phase motor or compressor the ohm readings across each leg will always be the same reading across each leg, ex:( L1 and L2 =3 ohms, L2 and L3= 3ohms, L3 and L1= 3ohms) this is just an example, some motors or compressors will be a different ohm number but the point is the ohms will be the same. If a motor is bad you’ll be able to tell if the bearing is shot, the shaft doesn’t spin free, or you don’t have continuity across each leg or you have a short on a leg. The reason this tool is useless bcuz this tool can say that the ohm reading is bad but in reality it’s not taking into account that the motor or compressor was running under a load for a long period of time when the test was performed. If you suspect the motor is bad CHANGE IT OUT, don’t waste your $ on this tool

Great tutorial JMT. Well presented and explained. It was an interesting and helpful video.
Thank you Bogdana! Appreciate the feedback. Glad you found this video helpful🙌 Stay tuned for new videos every week🔧⚡
Can I perform this test using this supco tool on an inverter compressor?? Please advise, thanks
Really nice simple video! Thank You

Thanks buddy good information… really comes on handy 👍
You're welcome & thank you for watching! Stay tuned for new videos every week 🔧⚡️
Thanks for sharing this with us
Great video jmt
Thank you dude! Much appreciated 🙏🔧⚡
subscribed💕 nice presentation and I'm also an hvac technician😊
So neat and well done as always.
What would it indicate if you went from L1 - L2
INSTEAD of
L1 - ground like you did in the video ?
It would show if L1 and L2 are shorted.
I have a Megger MIT420/2. You can shoot up to 1000 volt's and run a dAR test for 60 seconds.
How do you like that meter? Awesome. Those are so cool. Would love to get one of those
@@JumpermanTech You will love it. I do also have a cheap 150 dollar klein megger.
If one shows good then the other two are good
This guy knows something. But mostly a hack
A year ago he said a mega ohm meter wasn't necessary
