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.

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

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!
