Great video, cheers for the information, basics of the coils and testing.
Thank You
This is one of the few youtube videos I have viewed where the person has a true and good understanding of both electrical theory and mechanical aspects of these pumps. You explained well. My only issue is recommending that people should try spinning the shaft to see if motor works as sometimes the windings can go hard down to earth and protective devices are just not there or do not operate. If this is the case and you don't test insulation resistance first, then trying to spin the shaft while energized may just be the last thing they ever do.
Apart from that, I enjoyed the video and well done.
Good point. Glad you liked the video, and thanks for the nice comment!
Thank you for another very useful video. Almost all the motors I worked with were 3 phase 480 volts. Looking forward to your next video.
Your welcome. I don't think you need a start capacitor for a 3 phase induction motor. The 3 phases create a rotating magnetic field.

You are correct. No run capacitor needed. Really the starter for the 3 phase motor is the most complicated Part, Though once one understand"s it, it's not that bad. Cap banks are used to keep the power factor down.It's a money saver for Big manufacturing plant's. I would like a 100 dollar bill for all the motors I wired over the years. : ) Thank you for the reply
Thanks a lot, from Venezuela. Letś start checking with the tester.
You're welcome! Be sure to check out my video playlists and share.
Awesome channel. I have a spare 1.5hp 115/230v AC single speed pool pump and will use it for a future water project experiment running 24/7. Problem: it uses too much power for what I need (wastes electricity) and too fast (3500rpms). Is there a something I can add to the motor/circuit to make it draw less current (amps)?
concerning the 2 leads (hot and neutral), is the neutral tied to ground like a service panel in a house? and if so wouldn't there be continuity with the neutral wire and ground with the ohmmeter ? thanks for answer ...
Hello thank you for sharing,I need to ask you How can I secure the shaft so I can get the pump out ,I believe it turns counter clockwise? How can I lock the shaft so it won’t turn? Thanks 🙏

Thanks for this video! Very informative and helpful. I am having an issue where the motor will start but then shuts off after about 30 seconds and hums. I have replaced the capacitor, terminal board and V switch and still same result. From watching the video, I am now wondering if the problem is a bad run winding or possibly the centrifugal switch? Any ideas or suggestions???
Excellent video

Thanks for a GREAT video, question: IF the THERMAL OVERLOAD SWITCH you identify at 5:00m GOES BAD, will that cause the breaker to trip that feeds the power to the pump? I'm troubleshooting my shallow well above ground Goulds 115/230v irrigation pump (set & used at 115v). I replaced the capacitor already & triple checked timer, breaker & voltage (all is FINE). Or does this situation sound like we have a burned out start winding? NOTE: the motor shaft spins very nicely, no hang up at all. THANK YOU SIR!!!
+C-Jones Lawn & Tree
Hi there. The thermal switch will never cause the circuit breaker to trip. If you have full voltage at the motor terminals, then only a faulty capacitor or shorted winding would trip the circuit breaker. You can remove the start capacitor from the motor, tape off the terminals out of the way from moving parts, then power up the motor and CAREFULLY give the shaft a quick spin to see it the motor runs. If it does, then the start wining is shorted out,. You should have discovered that doing the resistance test on the start winding.
Thanks. Be sure to rate thumbs up and share.

So what dictates the motor direction? I'm used to 3phase. Done very little single phase stuff.
Good video!
The start winding. If you reverse the start winding connection, it should spin the other direction.
Thanks For Watching!
Great video, nice and detailed!! I have a question. My pool pump (1.5hp with only a start capacitor, just like the one in this vid) recently started turning off for a few seconds then on again for a few seconds. It will continue to alternate between off and on every 10-30 seconds until I shut it off. I replaced the capacitor because it was the easiest thing to do first, but it didn't fix it. What are the 2 or 3 most likely things that could be wrong in your opinion? Thanks!
Sounds like a faulty motor overload protector, or a faulty winding in the motor.
@@electronicsNmore Thanks, I'll check those!
It's great video really I interested with it
Plz I need the pics which in the video
Do screenshots using full screen high resolution and print them. Thanks for watching!
good info thank you but is it worth it to go through all that trouble when I can get a new ao Smith motor fore 125.00 brand new great. info
It's foolish to replace a motor that doesn't need to be replaced.
Tengo un motor identico al que muestras en el video pero no tengo los.digramas de conexion para 220v..
Me puedes ayudar?...gracias
Great Video! I have a US Motors 2 Speed motor(EB2977T). The color of the 5 wires is different from the color of the wires shown in your video. They are Red, Orange, violet, blue and white with black stripes. How do I translate these colors to the color of wires shown in your video? Thanks
You need to refer to the wiring diagram on your motor. You can take resistance measurements between all the wires to get an idea which lead to the run winding, and which lead to the start winding. Thanks for watching!
Hello sir, I am your new subscriber and I was amazed for the detailed explanation. Thank you so much for sharing your skills. I cannot find the images link on the motor pictures that you have shown. Can please send me the exact links for the images. Thank you so much...
I'll replace the links shortly. Thanks for watching! Be sure to share the video, and rate thumbs up.
I don't know much about shallow well pumps but I have changed a couple pressure switches(30/50) on my old 1.5hp Gould's J10 until I decided to finally get a new one. I snapped a pic of pressure switch terminals and wiring since both pumps are practically the same. . . recently I noticed whenever pump cuts in it clicks a few times before running.
Twice the pump stopped running(not breaker trip) but after I flip breaker to off then on again pump runs again.
I notice my kitchen light slightly flicker whenever new pump cuts in. My old pump never said this. New Gould's J10+ has 120/240v switch, old Gould's J10 was 240v on 2 pole switch. I set new pump to 240v as well.
I don't know what's going on?
Have you any video how to test capacitor? if you have then please tell me. i did not understand about DMM test of capacitor
Refer to my microwave oven parts testing video in my video list. When you place the probes of the DMM (using a 1K ohm range or higher)on the terminals of a DISCHARGED capacitor, the resistance should start out lower, then climb very high.
I have almost the exact motor your referencing in this video, my question is, I plan on using this pump(motor is attached) as a turbine to generate electricity in a micro-hydro electric configuration. I am curious if I turn on the water flow and bring the motor up to speed, will it be generating electricity or would I need to field flash the coil to start the process...? I know with a PMA you wouldn't require the field flash, and if i'm understanding it correctly a three phase motor could be phase shifted with capacitors to negate the need for field flashing the motor, but with a single phase motor like the one in this vid do you think it would be required...?
Please refer to this video:
How To Use An AC Motor(Induction or synchronous) As A Generator
The video explains how it is done. You need to spin the motor slightly faster than the rated RPM.

Thank you for taking the time to makes this video. Question: my Hayward .75hp pool pump starts & runs for about 10 seconds, then shuts off (does not trip the breaker). I changed the run capacitor, thinking it was the issue, but the problem persists. Since it does start, I must assume the start capacitor is good (maybe that's naive of me). The motor shaft spins freely. Any insight on what else I should examine?
Is there a pressure switch installed
@@electronicsNmore
I do not believe so. The motor is a Century .75hp, part number 7-196335-24. Similar in design, but not an exact replica, to the motor you used in this video. It's about 8 years old, and has had lots of runtime. It might just be tired. I don't mind buying a new motor, but I like to troubleshoot and try to find the root source of issues like this.
What is the rating of your capacitor, please ? I have the same motor you are demonstrating and the problem is the capacitor nameplate is gone. I want to buy the correct capaccitor. Thanks
You need to look up the motor online for the capacitor specs. Probably a 161-193mfd / 125V.
But you didn't test the red start wire to the other pole ( blue and white)?
In this sears motor I have the reading you are getting with the black and yellow and red is in mega ohms. The white and blue and red I get the reading you are getting with your wires here.
I want to hook up to 120V. Do I hook up the black wire to the purple? and supply power to white and yellow with the red to the capacitor and white as common?
I basically also like to ask what is the reading between all wires for 120/240 V motor coil set up?
Thank you very much.
There should be a diagram on the motor showing how to wire it.
I’m looking for videos on rewinding the motor
Hi Great movie i like to know what color weier goes together if i like to hook up to 110 volt
I have a hayworth 1.5 HP pool pump but i do not have the terminal bloc only all the weiers same coler as your video
Thanks Niels
Look up your model# online. :-)
Hi Again I have not found on line how to hook up by color of the weirs online it always say use A1 B2 and other terminal markings i only have all the weier ends coming out of the motor also the ower load and capacitor
Thanks Niels
Niels Bartholdy
Without a wiring diagram, I wouldn't know. Every motor is different. You need to research your motor model online.
If the motor is supposed to have a terminal block, you may be able to find one on Ebay
If the motor is running, can you use the start winding as a generator? I think it should. No idea if it can be useful.
This motor was used in an induction generator that I made years ago. I ended up switching to my inverter generator which is in my video list.
When I made the induction generator, I used BOTH windings for power. The main winding supplied most of the power to a 120V receptacle(60V per leg since there was no center tap on the winding), and the start winding supplied around 350W or slightly higher power output at a voltage which was a little higher than the main winding.
Once the motor is operating at full speed, you should be able to take power off of the start winding(red and black wires).
So I just got a pump with a plug .. how do I wire it to wires already coming out of my 230 box out side it can go 120 or 230 ? Help??
Ennrick LaFrance If indoors, then cut off the plug and strip the wires. You need to buy a 1/2" Romex clamp to secure it to your pump timer box. 120/240 conversion info should be shown on the motor.
I wonder if you could help me. I know just enough about this stuff not to be able to fix it. I believe I have a bad capacitor. Can I test it without removing it from the pump? Also, don't short it out before testing?
If you don't have a capacitor discharge tool, then short the terminals before touching the capacitor. Of course the power is OFF before you touch anything.
I want the diagram that you explain from it please
can you direct me to site that provides picture wiring diagram..thank you in adv.
Hi Ed,
Sometimes there is a wiring diagram for 120v/240v conversion on the rear side of the power supply metal plate(cover) on the motor. For a specific wiring diagram(including the windings), you need to look up the manufacturers name/model.
Thank You
hi video author, do u mind to post the wiring diagram that i can learn better from u. thanks
Hi there electronicsNmore new subscriber here. Our power supply is 220v. I bought a 1/3hp Gould Pump J03 Series from a scrapyard this morning. I opened it and it says 123mfd-140mfd 110-115v capacitor. I was not sure if it can run 220v or not. But I try to plug it to 220v abrultly and it turned. What will I do?
Respectfully,
Boolie Distura
I have no idea if you have a dual voltage motor. That's an obsolete motor. 220V motors use 110V caps. Thanks for watching!
@@electronicsNmore if I’m reading only around 115v should i change my pump motor to 120 rather than 220?
Can this motor run in reverse.
Reversing the start winding wires in relation to the run windings, should make it spin backwards.
My yellow wire came loose from the winging
Thanks for all the great vid's I'm enjoying and learning and hope to find some beginner projects I can get started on
