Most techs use a screwdriver but I show a way to make a capacitor discharge tool to satisfy the most nerdy or safety conscious tech.

All right, so first thing we need to do is discharge this capacitor now there's what everyone says that you should do. Who knows what they're talking about designed these things and there's what most technicians do most technicians will we'll just touch between the terminals on the capacitor, with a needlenose pliers or with a screwdriver? This is a screwdriver that I've adapted with a twenty thousand ohm resistor five watt, twenty thousand ohm five watt resistor - and you can see here. This tip - is one side of the resistor, and this alligator clip is the other side of the resistor. So, in order to do things the technically correct way, that's the right way to do it do most techs in the field.
Do that no, they don't have. I always done this. My career, no, I haven't, but this is the technically correct way now, even when you're working with this, though, because you got an alligator clip, you still have to be careful. In most cases, the capacitor will be discharged because it's allowed to discharge through the windings of the compressor, but there are some rare circumstances where it may still hold a charge.
So all you would do is you would just take the one side and you would wire it to the common terminal which is right here and then you would touch the hold on say it again. You take the one side and you connect it to the common terminal which - and this is kind of an awkward location, so I'm actually going to just connect this at the on the home side first and then I'm going to touch this over to common. That way, you know we're fully discharged and then I'm going to take this side, look at the common and then go to the fan side. So we know the fan is fully discharged again, most guys would just take a screwdriver and jam it in there.
You could potentially get a pretty big.
You can't see the terminals well enough in this video. Hope nobody died watching this Are you in Nepean ?
I am amazed about how this guy ignores completely the elephant in the room… The obvious lizard LOL.
Looks like the gecko already discharged it for you. Are you in Orleans ?
Can you discharge while still hooked to the unit?
I did and got sparks is that bad?
Or did I damage my home air conditioning unit ??
Now I know why it cost hundreds to replace $10 capacitor. It's life or death.
Does it work if I use the metal from the AC and touch with the screwdriver both one by one the connectors from the cap ? Service area Ottawa??
The way I discharge a capacitor is to grab a gecko and short the gecko over the terminals.
Did that lizard discharge it before hand?
My aircon compressor takes a long time to start, like 10-20mins or so.. and when it stops it takes too long again for it to engage..does that sound a bad capacitor?
Lizard leg galvanoscope?
HVAC techs always have been and still are exposed to electrical hazards yet never implement electrical shock &/or arc flash PPE when the work.
Be safe HVAC techs! You can die from electrocution just like an electrician can. Are you in Kanata ?
First step is to remove the dead animal.
Looks like the gecko did the job better.
Is that the gecko from Geico? I hope he had insurance.
You’ll fix it only though my dead body !
that lizard must of had a pacemaker. I'm so bummed…
Love that fried lizard as a warning lol
What's the worst that could happen by using the "other" method (screwdriver)?
Sometimes, I use a incandescent lamp, and after I use only the screwdriver
let's all spare a moment for the fried gecko <3 rip
Lizard discharged.
I hate when u tubers put up little windows for links to their other videos BLOCKING what they are showing in the current video, Thumbs own
This is done on the one being replaced or the new install or both ? Service area Barrhaven??
i slam it with a hammer lol
I usually touch it to my co workers legs to see if its hot. Waaaay more fun
why didn't you verify the discharge with a volt meter?
A capacitor on a washing machine motor will light you up every time, no where for that current to go,I do apt maintenance and work on all the HVAC and appliances
😆 I heard nothing you said while paying attention to that corpse lying on top of that capacitor. 🤣
Those dam gekos
I have always used my volt meter and I have always taught it that way.
is this method for all capacitors or is there a different method for certain capacitors?
LOL get rid of that dead lizard. Service area Kanata??
I always use my multi meter. Isn't that the right way?
I thought the discharging happened after you removed it completely from the wire connection? That did not look safe 👀
Most volt meters should provide more than 20,000 Ohms of impedance. Is there any reason you/we should not allow discharge through a voltmeter?
