Xpress power capacitor

Prior to installing capacitor manual says to hook up capacitor to battery till it has a voltage reading the same as the batery. I have tried twice only it is getting to about half. I am now charging my car battery prior to next attempt to make sure my battery is not the problem

Amplifier won't turn on

That's it. You need a stronger battery. Ideally a separate battery hooked up parallel to the original, with an upgraded alternator, and capacitor. That is pretty pricey, so if it won't work with the car running, first check wire size. The bigger the better. Bigger wires lose less voltage over distance. Try swapping out the battery for a bigger one, like the one in the car that the amp worked in. Then add capacitor.

I just bought a punch 500 a2 amp. i hook up my ground, then try to hook up the power cable and it sparks. my punch 250 was hooked up minutes prior to this so i know my wiring is good. what the heck is the...

The spark could be from the capacitors in the amplifier charging. Make sure the main fuse from your battery is still good and also check all the fuses on the amplifier. Verify all the wiring is correct and make sure none of the wires from inside the positive cable are poking out and touching the vehicle or amplifier chassis. If you have a 1k ohm resistor, you can put it in series with the amplifier power line to slowly charge the capacitors. You can do that by following the directions from the link below. After doing all that, remove the 1k resistor, hook it all up and try it again. If it still doesn't work, make sure your remote wire coming from the head unit has a voltage on it when the head unit is on. You can get a cheap volt meter from a hardware store or wal-mart.

Describe how to connect a scosche 500k micro farad

Put the capactior in parallel with your battery right before the amplifier. So Postive lead of cap to your 12 Volt line and negative lead goes to ground. It is also suggested that you charge the cap before placing it directly in parallel with the 12 volt rail. yo ucan do this by using a 1000 ohm resistor with a power rating of 1 watt. Disconnect your amplifiers so it is just your cap and battery. Replace the fuse with the 1000 ohm resistor. Once the resistor is in place hook up your cap. It will take a little bit for it to charge. RC time constant is T = Reistance X Capacitance. So 1000 ohms X .5 Farads = is about 8 minutes, or you can just measure the voltage with an volt meter and when the cap reads 12VDC you can then hook it up. BE CAREFUL NOT TO SHORT TERMINALS. THIS CAPACITOR I STORING A LOT OF CHARGE.

I have a lanzar vibe 255 can u help me?

Double check your connections. Use volt meter to co firm proper voltage. A test light can still light up with low vol
.A thumbs up would be greatly appreciated if this answer is helpful to you.

Power surge blowing fuses on amp when car is turned on.

the voltage regulator in the alternator or the capacitor is malfunctioning. get a multimeter on the battery when u start the car (before the capacitor) if it reads a large surge (something greater than 14 or 15 volts) then u may need a new amp, if not, then test it on the back end of capacitor to the chassie negative, see if u detect spike there.

2.0 Farad Capacitor

The answer is yes, any amount of amplifiers can be hooked up to a cap. Obviously the more amps you hook up to it the less you are going to nodice the difference with the same amout of farads. The only thing that I am worried about is the wiring from your battery to your cap. As long as you have a decent gauge wire running back you should have no problem. And for this instance I would recommend 0 guage, you might be able to get away with 4 but I would highly recommend 0. Over all I would recommend 0 guage on all installs unless you are going small and don't plan on upgrading. I hope I could help

Wrong connection continuation

If you're installing this in a vehicle with a 12 volt charging system (most automobiles are 12v), I think the batteries may be dead in your multimeter. You shouldn't read anything over ~15v.

When you measure this again, place the black lead on the ground terminal of the amp.

Phoenix digital 1.5 farad capacitor installation

First off Charging the capacitor can put you holding a high power voltage source. This can be very dangerous. It is enough to kill you. I suggest for safety go ahead and mount the capacitor in its location. The easy way to charge a capacitor is using a 12 volt Battery Charger. Hook the charger up to the capacitor just like it is a battery. + to + and - to - ... Charge the capacitor until the charger meter falls to near zero amps or indictates full charge. No need to use a light bulb or anything. The Charger comes with it own limiting circuitry. I will be posting the wiring instruction shortly.
