Here are some more information for Capacitor Cap:
Troubleshooting Monitor flyback transformers is not difficult if you know what is inside the flyback. Normally for a monitor flyback transformer, it consists of the casing, winding, pins, high voltage cable, anode cap, divider, epoxy and a high voltage capacitor. Among all, the internal capacitor gave the most problems. If this capacitor value out or short circuited, the monitor will have no high voltage and high voltage shut down and sometimes even blow the power section. That's why, whenever before you want to check any power problems or horizontal out transistor (HOT) that had developed a short circuit; you must always confirm first that the flyback transformer internal capacitor is working. Otherwise, after the replacement of components, the monitor would not work or sometimes the same components that you had changed would blow again.
Although every monitor flyback transformers have different designed, the method of measuring it is the same whether it is a Samsung, Philips, Likom and etc. Connect the digital capacitance probe from the anode cap to the bottom pin as shown in the photo. A good capacitor value should be from 1.5 nanofarad to 4.5 nanofarad. Acer 14 and 15" monitor usually measured 1.5-1.6 nanofarad whereas 17" and above flyback usually in the range of 2.7 nanofarad to 4.5 nanofarad. Some 21" monitor flyback have the reading of 6 nanofarad.
A good dynamic focus capacitor usually has the capacitance value from 0.5 to 1 nanofarad. If these capacitors values run, you may have some problems adjusting the focus. In other words, you just can't tune to a sharp picture no matter how hard you have tried it. You can test these dynamic focus capacitors by connecting a digital capacitance from the horizontal or vertical focus wire to one of the two pins under the flyback divider.
Many monitor repairers tried to fix a flyback transformer without success. Some called it as refurbish flyback. The reason for their failure in repairing the flyback is because of the bleeder resistor inside the flyback. Some technicians called it as feedback resistor. If you just remove the flyback internal capacitor pin and if that flyback have a bleeder resistor in it, the monitor will go into high voltage shutdown mode. Be careful when you want to do refurbishing flyback.
Get Monitor flyback transformers schematic diagram to make you familiar with the components inside the flyback. See how the internal capacitor and bleeder resistor are connected. How a primary and secondary winding are drawn and get to know the design of different flyback manufacturers as well. In this article I would not show you how to remove flyback transformer because I expect you already knew how to take it out.
Conclusion-Just practice more often on how to test a flyback transformer, and use a dick smith lopt tester to check the winding. It wouldn't take long for you to become very good in checking flyback transformer. By the way, testing the internal capacitor with a digital capacitance is not 100 % accurate because the internal capacitor have the voltage rating of about 30 to 35 kilovolt and the output voltage produced by your meter only in couples of volt. The best flyback transformer tester on earth is actually the Monitor or the TV itself. When you switch on, if the monitor working then the flyback is in good condition and if you heard "tic"-"tic" or arcing sound, most probably you need to check or refurbish the flyback transformer. Have a great day my friend!

Testing Capacitor - How To Test A Capacitor When Breakdown Under Load
Have you ever come across power problem where once you switch on the power supply and the fuse blow? You have checked all the components in the power (primary) and secondary section and all the components seems to be ok! Where is the fault? A fuse blown are usually caused by a shorted bridge rectifier, defective posistor, power transistor or FET, shorted primary winding of switch mode power transformer, shorted secondary diode and etc. But in this article I'm gone to show you another secret of electronic troubleshooting tips.
I got frustrated as to where is the cause of power problem. Every time when i switch on the power supply the fuse blow immediately (the fuse became dark color and this indicate that there is a major short circuit in the power supply). I have checked all the components in the power supply and can't find the culprit! What i do is i desoldered all the suspected parts one by one and replaced with a known good component. I eventually found the caused of the power supply problem. Guess what? It was the main filter capacitor (220 microfarad 400 volt). After replacing the filter cap the power supply worked perfectly fine. I begin my detective work to find out why this capacitor can caused the fuse to blow even though i already confirmed it ok with my meters.
The meters that i used to check the filter cap were analog meter, digital capacitance meter and esr meter. In this article i will not explain about how to check capacitor or testing capacitor and how capacitor work. I believed most of you know how to check capacitors and also generally using this type of meters. Measured with analog it showed capacitor charging and discharge, with digital capacitor tester it showed around 220 microfarad and with esr meter it showed low esr reading!
This proved that the bad capacitor breakdown when under full operating voltage. Then, how do i confirm that this filter capacitor is faulty? By using an analog insulation tester. When i connect the faulty cap to the meter and press the go button-it showed a very low resistance and this is the proved of short circuit between the plate when voltage applied! There is nothing to do with bad electrolyte. A good capacitor will just showed a charge and discharge in the insulation meter just like you are checking a capacitor using analog multimeter. In the market there is quite a number of ranges that you can buy. It has the range of 50v, 100v, 250v, 500v, 1000v and even 5000v! If you want to test a capacitor of 100 microfarad 160v then you have to select 100v. If you select 250v, it will blow your capacitor that is under test.
If you have the SENCORE TEST EQUIPMENT such as the sencore lc meter LC102 OR LC103, these meters have the capabilities of checking any type of capacitors with four tests:
-testing for capacitor values
-checking for leakage
-equivalent series resistance (ESR) and
-Dielectric absorption
It can check aluminum electrolytic capacitor, film capacitor, ceramic, high voltage capacitor and etc.
Conclusion-Different capacitor manufacturer produced different type of quality of a capacitor. Perhaps the bad capacitor that I encountered are from the lowest grade one. A capacitor failure when under load is very rare. Using ESR capacitor meter alone can solve most of the electrolytic capacitor problem.

Im about to run two kicker l712's off a 1600w brutus amp. What size cap (Capacitor)do i need ?
My car is a 05 caddy sts. I just dont want my lights dimming or my system getting weak. I will also be using an epicenter. Will a cheap crossover help?
Agreed dont get a cap. if you are going the easy way out like that which is the wrong way get a nice optima battery instead of a cap itll work better for longer, but your alternator wont be able to handle the load so youll need to recharge the battery at your home to keep your alternator from failing. Basically you need to get a HO alternator and upgrade the big three. I, contrary to many others beliefs suggest a second battery for running the system if you dont want you car always on also.
