how to figure out the Farad rating on a capacitor?

[closetcanibal]

This isn't as easy as the title sounds. I got a free Capacitor from a friend. The Capacitor literally says nothing on it. No label of any sort, or any impressions in the aluminum housing (aside from scratches and dings from age) to give me any indication of the Farad rating. Is there any sort of way to test the storage or output to determine the farad rating?

^^^^^ what he said

they are junk, not worth the wire and connectors to hook it up.

capacitors have their place, just because you guys don't know how to use them doesn't mean they are worthless

I know it's crap, but I'm still curious how you would figure something like that out?

worthless in his set up, along with the chance that it is 1 or less farad

The question still remains though, Is there a way to figure out what the rating is?

I'll be running 3 caps along with the 2 batteries in my car. one on constant power, one on ignition power, and one on amps. I have no idea what his system is but it won't hurt anything really

would a Capacitance Meter work?

I would toss it, from what ive heard, If you dont have enough Fared's it could hurt but you dont have to worry about too much Fared.....BUT keep in mind I am a newbie to this. lol

I am pretty sure I know how to use a capacitor.

step 1) remove from car

step 2) place on shelf in garage

That is what I have done with the 15 farad that I was sold back in the day
