1) Discharge the capacitor by shortening its leads. that is - use a wire and connect the leads of the capacitor together. this will discharge it.
2) Put your multimeter in the high ranges 10k-1m
3) Connect multimeter to capacitor leads(observe the polarity if electrolytic). at soon as the leads make contact, the meter will swing near zero. it will then move slowly toward infinity. finally the meter would come to be infinite ohms because the capacitor is being charged by the battery of the multimeter.
4) If the capacitor is bad, it will go to zero ohms and remain there. this is called a shortened capacitor
5) In the case of an open capacitor there will be no ohmmeter indication.
6) Some capacitors have a low dielectric leakage. you will know this if the ohmmeter comes to rest at a point lower than infinite. test a known good capacitor of the same type to be sure.
 This test works for large capacitors. Tiny capacitors can only be checked with a capacitance meter, or by using them in an AC circuit and checking for variation from calculated voltage drop.
Pls. focus on jb most strong series:  JFB--MKT (Metallized Polyester ) Film Capacitors &JFV--X2 MKP (Metallized Polypropylene) Film Capacitors.

Hello! Sirs,

First ,wish you a prosperous new year .Then let me introduce some basic technical information for car audio electronics DIY to you.

A capacitor is an electronic device which consists of two plates (electrically conductive material) separated by an insulator. The capacitor's value (its 'capacitance') is largely determined by the total surface area of the plates and the distance between the plates (determined by the insulator's thickness). A capacitor's value is commonly referred to in microfarads, one millionth of a farad. It is expressed in micro farads because the farad is such a large amount of capacitance that it would be impractical to use in most situations. Film Capacitors:

Many low value capacitors (less than 1 microfarad) will have a plastic type of insulator (polyethylene, polypropylene...) between the plates. Sometimes the plates are actually a metallized layer bonded onto one side of the plastic material. Multiple layers of the metalized plastic material make up the capacitor. Adding layers or increasing the size of the layers (without increasing the thickness of the layers) will increase capacitance. The following diagram is an incredibly generic film capacitor. You can see the dark blue insulating film between the cyan and violet plates. The plates are soldered to one of the terminals on one end of the plates. Half of the plates are soldered to terminal A and the other half of the plates are soldered to terminal B .Please refer to below drawing which tell you how a capacitor works.

A capacitor is a small device that can be charged up with electrical energy, store it and then release it. Just like a rechargeable battery. But unlike a battery, it does not use a chemical reaction and it can only hold a very small charge. A very large capacitor can only light up an LED for a few seconds. They come in many shapes and sizes and a few are shown below. The bigger the capacitor, the more charge it will hold. Capacitor is made from two metal plates or metal foils separated by an insulator called a Dielectric material.

The Dielectric materials can be made from Ceramic, Mica, Polypropylene, Polyester, Electrolytic, Tantalum and even air.

The larger capacitors look like tubes, this is because the metal foil plates are rolled up with an insulating dielectric material sandwiched in between.

The value of capacitance is determined by

1.The size of the plates,

2.The distance between them,

3.The type of dilectric material used.
