Some say yes, some say no, i have the resistor, is there a need to charge it?
DAXX c10 1 farad cap

 

yes

 

If you don't mind sparks when you connect it no. The resistor just slowly charges the cap. The resistor is a current limiter.

point taken, but a 10F cap....that's going to be one hell of a spark....

btw, don't hold the resistor in your hand - it would be far smarter to use a lightbulb. When the bulb turns off, the cap is charged.

 

are you referring to charging or discharging the cap? As far as i was aware you use the resistor to discharge the stored energy in the cap before installing it so you dont take the risk of spraking like hell and possibly damaging it. This goes true with some amps also. Mosty Hi current ones. As far as charging it, when you hook it up and let the car run, that should be how you correctly charge the cap.

Correct me if im wrong here, but this is simple electronics.

You are wrong Well, not wrong, just backward.

You charge the cap before you install, discharge it after. Like it was mentioned above, if you don't, you will have some nice sparks when you attempt to connect the cap b/c it's going to suck up current.

Some amps that had large cap banks built in - the soundstream reference 1000's come to mind - advised people to charge the amp first before attaching the power wire.

The resistor/bulb/whatever, is just there to slow the current flow into the item being charged. This is why I use a 12V test light. Hook up the ground to the cap. Then hook one side of the test light to the positive side of the cap, the other end to the positive wire. hold it there until the light is COMPLETELY out. Then attach the power wire and you are good to go. To discharge, just connect the lamp across the terminals of the cap - when the light is out, cap is discharged.

 

ok, i get what you are saying. i was backwards in my thinking i know with my soundstream stuff i had to charge them 1st. i thought it was discharging them though. lol
