Need help installing a cap

[Cartman]

I tried to install a cap today and it didn't go so well, had a couple of problems;

When i was charging it I attached the the postive part of the resistor thing to my power wire, the negative went to a ground that I use for my amp. The manual says charging takes a couple of seconds until a green light is supposed to go off, I had it charging for over a minute, light never went off but I figured it was charged.

Then when I wired it to the system I had the main fuse removed, installed power wire to cap, other power wire from cap to distrubtion block, and ground wire to a good ground. When the fuse was put back in is started sparking then the fuse blew. Got a new fuse and tried charging the cap again, again charged for over a minute and checked the voltage and it as less then 1 volt, so I must be charging it wrong.

are you sure your ground is good?

and your charging it with the fuse in?

It is the same ground that I used for one of my amps (I had each amp going to different grounds, now they both go the same spot, and the cap gets the old amp ground) and it worked for the amp fine.

The fuse on the power wire near the battery was in place, that was then connected to the resistor and the ground of the resistor was connected to the ground wire. Thats all I did for charging it.

No fluid came out or anything but could the cap be blown?

Damn, the idiots who put the led display thing on marked the terminals wrong - I only found out after pulling off the led voltage thing. I hope it not blown, will try charging it with the right connection in the morning

that shouldnt have done anything to harm it. reversing the polarity wouldn't damage it- although i'm not too clear on just what you mean about them reversing something and i'm a little wasted right now so yeah

Everything seems to be working now - voltage reading of 14.8 with engine at idle and 12.4 volts off battery.

The top part of the cap was installed by the company that I got it from onto a RF cap, when they installed it they messed up.

All good now
