I've got an old motor with a start capacitor, the motor only hums when I try to start it. I cleaned the centrifugal switch contacts and it still only hums on start...... so I wanted to test the capacitor and that's how I wound up here. Now I shall go test the capacitor, I'll be right back with the results........ and I'm back and still alive .... the capacitor on the motor is DEAD, won't hold a charge after numerous attempts. Another capacitor I happened to have did hold a charge and a nice spark on the run and start side. I 'll order the correct capacitor for the old motor and see if that will get it to start properly. Thanks for the youtube. No telling how many motors go to the scrap yard when a new capacitor would fix them. Thanks again.

The first way looks the best fun but please use a quick test block or similar. These are designed to temporarily connect things to the mains. Just makes it a bit safer for you. Thank you so much for posting:)

But I have question,, if that dead dry battery acid use like they way done to use salt with water. So if you put salt with water for that dry dead Battery so you gona using only salt with water or u can put also acid in that battery?

Excellent. We can measure the capacity of 30uF using another capacitor. If we have another 30uF, we put them in series and we have 15uF. If we have one under 20uF, we measure it and we find the value = a, then we put it in series with the larger capacitor and we find the value = b, b

thank you for valuable knowledge

Thank you. This trick really useful for my trouble since I only have a multimeter without capacitance meter. My air con capacitor shows still charge and discharge by the multimeter, but how can I know that the function is still good?

It should be realized that when applying a capacitor to AC mains and removing it, there will be a DC voltage present. The size of the voltage will be determined by when the supply was removed in the AC cycle. It could be anywhere between 0 and +/- 340V DC ( as the peak DC voltage is 1.414 times the AC RMS voltage, My method is to connect the capacitor to a IEC lead, plugging it into a power point and switching the power ON and OFF briefly. I then remove the lead from the mains supply & I measure the voltage with the multimeter and look for a voltage >300 Volts. Discharge the capacitor by short circuiting it and repeat the process several times for voltage >300 Volts. Then measure the voltage every 5 minutes or so & if the capacitor is still charged to the same voltage, you have a good capacitor. If not it is leaky to some degree and should be replaced. Discharge the capacitor before removing it from the IEC connector! I don't think we should be showing anyone "poking things into power points directly" If you do this sort of testing a lot, make up a lead with insulated alligator clips (sometimes know as a suicide cord), but do not leave it lying around!

I have a portable air conditioner that doesn't work. I have removed the start capacitor and tested the resistance and it's on overload no matter what ohm setting I put my multimeter on. I have tried charging it, and discharging it and it's always the same. Is it safe to assume the capacitor is dead?

Please can I change the capacitor of a summersible control box with a higher one with higher microfarad?

Please note that, while doing this, I suggest that capacitor not to be connected directly even little time, since we want check capacitor is Ok or nor, there may be open or short internal, it should be always to be connected one series lamp with this, so the test will be safe, if not incase short, it will explode with no time.

could you please explain third method (or please refer to link explaining etc...)? how capacitor is charging without a source ?

@KesienaBrown

The multimeter has a souce. Recall to measure resistance, you need v=IR, so the resistance of the capacitor increases with increase in charging and vice versa.

Buy a new one.. you can test the old won using the continuity on your VOM to charge and test. Apply leads then reverse you should see a voltage kick if still good...

You can charge capacitor by use a diode for high voltage. In this way you can charge at max voltage all the capacity.

If no centrifugal switch connected in series with the capacitor then the capacitor remains connected during running period. Please always replace the capacitor having the same rating (uf must be same, voltage and temp can be higher or same) for both start and run capacitors.

Why you charge the capacitor for a fraction of a second only. Is there a problem if we keep in charging for hours?

What is the voltage of the buzzer..?? Since the capacitor is of high voltage.

How about polarity capacitor if there is negative and pacitive like 50 Volt ,100 uf

The method itself riskly. As the capacitance is high so high current will flow through it which can damage it. So connect it for a fraction of second to charge the capacitor.

Yeah, never use a load like a light globe, just short it and damage it further......... I wonder how many videos didn't get made because the person was injured or killed.

for a 3 wires ac motor (common wire, start and run winding) which wire should be plugged to capacitor? is it right to plug the common from the motor to neutral, live to capacitor which the other wires are plugged to the two terminal of the capacitor? or live to common and neutral to capacitor?
