Bro you have no idea what you are talking about, that is WAY dangerous, I have been installing for 14years believe me your so called Teacher is a RETARD.

I am sorry but I agree, I would go with the light bulb method...

I have always used a turn signal bulb to charge and discharge.
To discharge, wire up the bulb as if the cap was a battery. To charge, wire the bulb in series with the power wire.
It is not a good idea to suddenly charge or discharge a cap. Something about the fluid inside, but I can't remember exactly why. Not to mention EVERY manufacturer recommends a slow charge or discharge. There must be a reason.

I am curious have you ever seen a cap fail by shorting or doing a fast charge? I know it is not recommended and I have been less than religious on this so I have no axe to grind.

I have not seen it personaly nor do i want to...lol , Like others have pointed out there must be a reason why EVERY manufacturer recomends a slow charge, and to the guy that suggested touching the terminals together do you also discharge your battery by placing a wrench accross the terminals...lol is that how they teach you at the Big Box store you work at.....

That would be SPL-type of discharging, if you need SQ job it costs a little more. I can do you a favour and do it for $125, cause I am a very nice guy.

you will damage the cap or the batt depending on what you are using and it will no longer work at full capacity and it will have a shorter life span... I have seen this a few times more in batteries but a cap is pretty much a battery.

Lay off on the the big box thing we dont short caps out we hit them with an axe just below the terminals and then sell a new one LOL

I have seen it personally, the cap DID blow well kinda it expanded sort of what a full pop can does when left in the heat. It did not work again not to mention the third degree burns suffered by the dumb **s who shorted it. I though it was funny though, told him not to but he didn't listen. I remember reading somewhere that a fully discharged cap is theoretically a ground and is the reason why the slow charge is required. I think it was that when it's discharged it has nearly no resistance and acts like a ground, but when you use a test light or a resistor it deals with that problem
