Can someone please refresh my memory on how to discharge a capacitor and also how to install one as it is has been ages since I've done one. A friend o mine wants me to install it in his truck. he had it in his last vehicle and had his stereo shop remove it so I don't know if they discharged it. Does this matter? Please advice.

 

Hey, I would try hooking it up first, if they didn't discharge it then it should still be good to go. I had mine sitting for almost 2 years in the house. Never discharged it when I removed it, just put it back in, put the power to it and it fired right up and has had no issues since. I will check when I get home and see if I can find the resister I had for charging mine. If I can actually find it you are more than welcome to borrow it if it is needed. Try it first tho as I doubt they would have taken the time to discharge it.

to discharge just connect both + and - together and make a spark. install and recharge with a resistor or a little 12 volt light till it dims out

 

DO NOT CONNECT + and - together unless you are trying to blow it up. As for charging a resistor or a light in series with the + will work.

 

Connect it to your amp, leave the REM wire on, disconnect wire from battery to cap. Turn on your amp

 

it wont blow the cap lol the teacher showed me to do that. yes it makes a spark but IT DOES NOT BLOW IT. i did it for mine and then recharged it for install and its fine

 

as i recall, the same resistor used to charge the cap can be touched between the + and - posts, but why would ya? still seems like a good way to break stuff

 

wire a light between the + and - when it goes out its discharged
wire the light between the + post and the battery, when it goes out its charged

 

or ditch the cap and buy a batt

 

this needs to be done very carefully, bring it to me and i will discharge it for you for $20. Also can install it for you for only $80. Or for $100 I can do both.
