charging capacitors

How do you charge a capacitor? Sorry i just don't really know and i just got a one. I got a new battery and a good alt. so i have a cap now and i dont really know what to do with it. Can someone please help Thanks!Hello.

The only reason they suggest charging a capacitor is to avoid the nasty arc that could De-Blingify the pretty connectors on the cap. Best thing to do is to return it and get your money back. It will help nothing. If you insist on charging it properly, using an old fashioned test light, you know the ones with an actual light bulb inside of them. Not a fancy LED light. Connect the power wire to the capacitor. Now take the test light and ground the alligator clip to the chassis of the vehicle. Touch and hold the probe to the negative terminal of the cap. When the light goes out or gets really really dim, your cap is charged.

capacitors seriously aren't worth it? They have to serve some sort of positive purpose.Hello.

haha...so literally nothing...i think i should take your advise and return it huhHello.

Can i use the resistor to charge it rather than a test bulb?Hello.

Yes you can use the resistor.  The test light will let you know when it is charged.  Using the resistor, you will need a volt meter to see if it is charged.  It will be devastating to you if you connect it before it is charged and it arcs a mark on the connector.

well i have this little light with two wires coming off of the bottom, it's halogen but it says use only with 120volts, can i use this light? Or is it too powerfulHello.

oh and the cap has a built in volt meter, i dont need another one do i? Just charge it up until its at like 9 voltsHello.
