SOURCE: Will my car handle a rockford fosgat 801s power load?

Hello dreww1005,

If your alternator and battery are in good condition, you probably don't need a capacitor. At maximum output, the 801S will need to draw a little over 30 amps at 12.8V. The specifications call for 8-gauge power and ground wiring and a 40A primary fuse. The Vibe's electrical system should be able to handle it OK.

Hope this helps.

SOURCE: need to know how many ohms this amp is

Safe down to 2 ohms, NOT a 1 ohm stable amp, it will be pushing it hard even at 2ohms but Fosgate's should be able to handle it providing that the install and all cables,wire,connections,etc. are sanitary!
Good Luck !

22v1e74 capacitor value

sets will have more than one cap and in fact sets with 100 or more are not uncommon. Most filter caps (there are several other types) will have the value and max working voltage plus which is the positive and which the negative lead printed right on the part.

Need capacitor value for 200-000-tips110h c30

If a filter cap value will be marked right on side: like 220 uf 16vdc which is 220 microfarad at 16 volts dc--

note also the - stripe on one side= negative and the + which is positive which will also be marked on the board.

In hardware monitor i see bad values of voltage, if i measure with a multimeter the values are ok. after about 3 minutes the pc shout down. i cant find manual or schematic all tested links dont...

1) Do the voltage values stay the same right before the shutdown, or do they drop?

2) Plus, Voltage values; Are you getting a full 3.3 Volts, 5 Volts, and 12 Volts?

3) Check the Electrolytic Capacitors on the motherboard for visual signs of failure.

A) Electrolytic Capacitors are used on the motherboard as Filters, or Voltage Regulators, (Motherboard voltage regulator circuit)

B) Computer designers know that Electrolytic Capacitors break down over time. This is why they use capacitors that are rated at 50 percent more than is needed. When the capacitor (Electrolytic) breaks down to the 50 percent level, it is still good enough.

C) The Electrolytic Capacitors used on the motherboard are Radial Aluminum Electrolytic Capacitors.

Basic construction of a R.A.E.C. is;
1) A cylindrical aluminum case shaped like a Coca-Cola can, but with no top, or bottom

2) Top seal is a Vent Cover. A flat round thin disk composed of Aluminum, that has a shape etched partway into it, in the middle. Usually a K or X.

3) Bottom seal is a Bung. A flat round thin disk composed of synthetic rubber.

4) Three strips.
A) One strip is metal tinfoil composed of Aluminum.
B) One strip is also aluminum tinfoil, but has a non-conducting medium applied to it.
C) One strip is a paper-like strip that is soaked with Electrolytic Paste.

Strip A is the Conducting strip. It has the Positive lead, (Think wire) attached to it.
Strip B is the Non-Conducting strip. It has the Negative lead attached to it.

Strip C is placed in-between Strip A and B, and all three are rolled up tightly.
The Positive lead, and Negative lead, poke down through the Bung at the bottom of the capacitor.

When the capacitor starts to fail a gas is developed inside. (Hydrogen Gas) The paste breaks down, and makes the gas.

The gas expands, and breaks the top Vent Cover open at the K or X, AND/OR, pushes one side edge of the Bung out.

The gas then slowly pushes the Electrolytic Paste out. (It oozes out)

So much paste loss, and the capacitor operates at a weakened state.
Too much paste loss, and the capacitor fails.

The paste can also dry up inside, and show no visual outward signs of failure.

Power unplugged to computer, Anti-Static Precautions observed, the motherboard should be removed for visual inspection of the capacitors.
It may require using a magnifying glass, and a good light.

My computer suddenly shutdown. The 3 condensators near the cpu are inflated. Howe can I test my motherboard (gigabyte 8s661fxm-rz) to see if this is the problem? Sorry for my bad enghlish!


If the capacitors that are inflated on *********** board they will have to be replaced.

There is a high probability that your machine shut down because these capacitors have failed.

They are actually fairly easy to replace, IF you are experienced doing soldering of this type. They are probably the easiest thing (soldered in) to replace on a mother board.

If you want to try, make a note of their values. You you see something like '600uf 12v' on them. This means 600 microfarad 12 volts. Purchase new capacitors (these are electrolytic capacitors) that match these values. They are inexpensive. If there are more than one value then make a drawing showing the location of the various values.

These capacitors must be reinstalled with the correct polarity. On the board there will be either a white circle with half the circle filled in or some other marking. The marking always indicates the negative terminal. The negative terminal is marked on the capacitor with a row of arrows (->->->).

Have an infinity entra sub two. Has burnt capacitors at c72. Has two capicitors, (one on each side of pc board) need to know values

The values will be printed right on the capacitors themselves.
it will look like 1000uF 25V for example. That would be a one thousand micro-farad capacitor at 25 volts.
You may need to pull the capacitors to be able to read them.

I have the a Philips Ambilight TV too. The power supply has two capacitors that may be going bad. Check the pic here... My question is what are the number(values) and brand name of the those...

Don't know what you mean by picture here ( cant see it) but if capacitors look swelled ie domed , swelled in any way distorted , replace them, look out value , say 100uf , voltage , say 100v, and running temprature , say 105 c.
replace with exact part and make sure of polarity, the capacitor has a stripe on one side for negative connection

hope this helps
this job is not for a novice though

On an electrolytic it is marked at the NEGATIVE terminal by a Black Stripe, or the like, on the NEGATIVE side of the Capacitor, that always goes to Negative/Earth. The other one is of course Positive. They are orientated with the Neg on the Black side of the PCB markings.

What are the locations for the capacitors on the LN26A330 power supply circuit board? What capacitors go in what location.

All the capacitors will have location numbers printed on the bottom and top of the circuit board next to them like C18 etc--the values of each will be printed on each capacitor--as well as one side of each will have a strip with - which means it is the negative side of the cap and the other side will be the + or positive side--look for ones that are puffed up on top---see attached photo of a new and good cap--the silver top with the creases should be perfectly flat.

Any bad ones should be visible to the naked eye.

Let me know what you find---if you find puffed up ones they will be marked also with a value like 1000 mfd (microfarad) at 10 v (means the cap is rated at 10 volts.)

If you find bad ones it is a good idea to replace with a higher voltage rated cap of the same value--it may present a small problem as the higher the voltage rating is the bigger the part will be.

The reason (if you have puffed up ones) they fail is because too low a voltage rated cap was used when the set was made---saves the company who makes the sets a few cents on each part.

Let me know if you have questions of need advice.



note the gray band on the left side--negative lead (each has 2 leads) is indicated that way.

Dell monitor not working , green light blinks.

Capacitors look like cylinders mounted vertically on the pcb.

If you look at the printing on the board, there should be a label close to the capacitors such as C201, or XC330.

Usually a C in the label will indicate a capacitor.

They will be wrapped in a plastic jacket. The jacket will have writing on it, and usually a stripe down one side. The stripe indicates the negative lead (each cap will have two leads, negative and positive).
If the cap has a rounded top (domed) instead of a flat top, it is likely bad. You may even see that the component has split at the top, into four pie shaped wedges. This is also an indication of a bad cap. Lastly, the jacket is "heat shrunk" onto the metal cylinder. This usually causes the plastic jacket to overlap the top of the cylinder, which will show up as a donut shaped ring around the top of the cylinder. Some times if the cap is leaking, it will heat up causing the ring to shrink further so that the top of the cap will be completely exposed metal, with no plastic ring framing it. This also indicates a bad cap.

You can get the value from reading the print on the side of the cylinder. The values should be printed down the side of the cap, such as: 1000uF 16V, or 470uF 25V.

This is read as one thousand micro Farads at sixteen Volts, or four hundred seventy micro Farads at twenty five Volts (the u will actually be the Greek letter mu).

You will need a solder ****** to remove the solder from the caps on the solder side of the pcb (under $20), a soldering iron and some solder.

**** the solder after heating it with the iron, use the tip of the iron to carefully unbend the legs of the capacitors if needed.

Install the new caps making sure to observe the polarity. There will either be a mark in the board indicating where the negative lead should go, or a small + showing where the positive lead should go. Solder the leads and cut off the excess.

Make sure you get caps that are not larger physically than the originals or you may not be able to fit them into the same spot. (older capacitors are bigger than the same value newer capacitors).

Hopefully, you will only have three to six caps.

The lucky people will find only one bad cap, unlucky people will find up to ten bad caps, some in the power circuit, some in the inverter circuit, and some on the main board.

Caps on the main board can be very tough to remove. I recommend adding some solder to the legs of the caps you are going to remove, then heat one leg as you push the cap to the side to try and pull that leg out of the solder hole. Then heat the other leg and try to pull the cap completely off the pcb. Once done, you can use the solder ****** to clean the old solder out of the holes. This may be necessary because the main board is multilayer and these layers can act as a heat sink, making the solder harder to melt and harder for your solder ****** to remove. It's slightly easier once the capacitor legs have been removed.

Also note. Some manufacturers will use slightly larger caps, and in order to mount them they will bend the legs and glue the cap to the board on its side.

DVD stuck inside, player won't turn on, standby light does NOT flash

test the capacitor with a meter to make sure it has the value stated on it.
the work on this unit is quickly exceeding its present value, most likely.
consider upgrading to a higher resolution unit if the fix is more expensive in parts and time than a new unit costs.
good luck
