How to Test Fan Capacitor Easy and quickly

now lets to test this capacitor with this new method, only need a capacitor and a power outlet.

Great, just the information I was looking for! Short and simple instructions. Thanks!

I'm starting to think they run down and the fan runs slower with an old capacitor. I tried connecting several old capacitors one at a time to test the fan speed with each one. Some were slower than others and I even doubled using two old capacitors and the fan worked well and worked beter than with each capacitor separately! I checked the lubrication before working with the capacitors, of course.

The caps found in the flash circuit of disposable cameras are small but have a good punch to them. Ive accidentally rigged them up inside of the handle of my mag lights connecting to the main power button. Remove the rubber and secure the lead to the plastic part of the switch with a tiny screw or glue. When the button is pushed to turn the light on it waill shock the hell out of who ever pushed it. They are fun to install inside your remotes too.

You just CAN'T be serious about this! 😳 You MUST be kidding us! NEVER EVER stick a capacitor of unknown condition into a power outlet like this! If it's bad, very unpleasant things may happen, ranging from a power shortcut to the cap exploding right into your face. And you should NEVER discharge a capacitor by just shorting its wires, as this may damage it permanently. Always use a voltage meter to test and only discharge with a high ohm resistor. Keep your fingers as far away from the wire ends as possible. The testing wires of a meter are thoroughly isolated for a reason. I hope you have a good life insurance. 🙄 By the way, that spark test may look like fun, but it tells you nothing about the real condition of the cap. If it had already degraded from 4uF to 2 uF, it will still produce a spark, but may already be too weak to drive the motor propetly.

You can do it with an OHM meter. You can see the charge and discharge by watching the needle on the meter..

It would be better if you use a bulb to check if it is charged

capacitor +/-5% we call it Tolerence not mistake as you said

[davidreynolds]

You can buy a 20, 000 ohm resister to safely discharge caps. And it wont l damage the cap. For those who dont know what youre doing or what a cap does. Once a cap is charged it can hold that charge indefinitely. If you grab it and touch the terminals or wires best case scenario youll get a tingle. Depending on the voltage and mf youll be lucky if you only piss yourself.

I have same one but it has 2 red wires and my fan is not even 3 months old 😢

we invented multimeters over 100years ago.

Do not touch one wire to your thigh & the other to your winky. Or you will get a tinkle from your winky.

Touch one to your lengua other to youe ojito!!!

I would NEVER do anything like this EVER
