new fuse = capacitor alarm

[frijolesfrios]

Hello everyone, I'm new to the 12v game and this is my first build. I have two 12" JL W6's running off of a JL 1000/1 at 2 ohms with a tsunami 5 farad cap and 4 gauge wiring throughout. A couple of days ago I blew the 80amp inline fuse. Today I went and bought a new 100amp anl fuse, installed it and when I turned the car on to see if everything was back to normal, the capacitor was beeping and reading 160V on the display. For now I disconnected the power cable to the cap so it wouldn't beep while I drive but I have no bass. Thanks in advance for the help.

got the cap grounded corectly? theres no way it could be getting 160v

ditch the cap. problem solved

Cap was likely completely drained, they need some type of resistor to recharge correctly. I dont mess with caps so im not sure exactly.

im pretty sure its grounded correctly, i might have read the display wrong, but it said 160 (not sure what the unit of measure was).

16.0 v?

16.0 v?

That would be my guess...although I am also in the camp "Ditch the cap". //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

ok so i went and checked the cap this morning and it reads 160A and also I think that my amp might be toast. I started smelling melting plastic and disconnected as fast as I could. I drove my car around the block with my amp powered straight from the battery and it works, but my battery light on my dash comes on. If I turn my stereo off the light goes away.

to rechare the cap, you have to hook it to a lightbulb and charge it up, but i think its fully charged when the bulb goes off

is your battery stock?

i used a testing light, but it never went off. It charged it though to about 12 volts. Theres vids on youtube on how to do this.

edit: and if you cap says 160 and your fuse is an 80 won't it blow? Try a 200

I recently installed an optima yellow top, and yes I have a 100 Amp fuse which is still good but the cap read 160 Amps which doesn't make sense.

fu ck charging bulbs and light just spark it a couple times thatll charge it but im in the club DITCH THE CAP too. get a cheap *** walmart battery for starters (49.99-79.99, less than the cap in guessing) or a kinetik hc600 ~100.00. capa are worthless there for voltage reserve not amperage an amp needs amperage to work better.

Ditch the cap like others have said and do the big 3.
