My friend gave me a cap of his, and I hooked it up the digital read out read 0.00. A few minutes later the read out was blank. But power was still going to my amp. Is my cap broken or does anyone know how to get the readout back. Not sure what the brand of the cap is b/c the label is torn.

 

Often times those display caps have a terminal for the remote wire. Did you hook that up?

How exactly did you connect the cap?

 

The leds will only blink the readout for a few seconds when the amps been turned off or on.

Hook it up in parallel. And just like he mentioned, make sure to hook up the readout wire if there is one (usually a ground).

 

I hooked it up like this: <center>

I don't see a remote wire for it..

 

Most cap has to be charge. They usually come with a charge card.

 

you have the power wire from the battery to the caps negative terminal, take the power wire from the battery and hook it up to the positive terminal along with the power going to the amp then ground the cap.

So basically take the power you have from the battery hook it up on the same terminal the wire going to your amp is on then just ground the cap to the chassis

 

You probably damaged your cap. You wired it for reverse polarity. What made you connect red and black together (red power wire from battery and black negative terminal on the cap)? The cap goes in parallel with the power and ground.

 

You need to hook the positive terminal up to the battery, and the positive from the capacitor into the amplifier, then the negative to a vehicle chasis ground, preferably into the same ground loc. as the amplifier.
The way i do it is i connect all the positive wires to a distribution block and that way its a clean install.

 

Problem solved! Thanks everyone for your help.

 

Another quick question, what numbers should my cap be putting out. the numbers right now are ranging from 12-14. I'm running 2 Alpine type S subs if that matters.

 

That's about right. Nothing to worry about.

Actually the polarity was correct.

But he had it in series instead of parallel. Series the cap will act like a high pass filter instead of a stiffening cap. A cap in series will block DC. I'm actually shocked the amp even worked. If the amp did work that might be an indication the cap is already damaged.

Cap needs to be in parallel.

You cap isn't "putting out" anything. Meaning the voltage you are reading is the voltage the alternator or car battery is "putting out".

You cap is a short term storage device. Similiar to a glass with water in it. You have to get the water (electricty) from somewhere else. The only time the capcitor will "put out" is when the alternator drops below 14.4 volts.
