Depending on the value, it varies.
Using a multimeter set for Kilohms resistance, check that it appears open circuit. This may be hard to determine, due to other components in circuit. It should NOT show zero resistance.
Electrolytic capacitors above 1 microFarad will show some storage of charge.
Using the meter with the probes one way, there should be a percepible rise of resistance. Reverve the leads and you should get an intial negative value followed by a slow rise in resistance.
If there is no perceptible rise, it could be open circuit. If it shows Zero, it will indicate a dead short.

How do you know if a capacitor is good or not?
You test it.For electrolytic capacitors, it's sometimes (but not always) obvious simply by looking at it that there is a problem; if the capacitor bulges or is actually ruptured, that's a pretty good indication that it might be bad. However, the only way to know for certain is to check it to see if it has the proper capacitance.For various reasons it's difficult to test the capacitance of a capacitor which is in a circuit; you'll usually need to detach it and test it in isolation. It is possible to check the equivalent series resistance of a capacitor without removing it from the circuit, and in some cases this may be enough (a correct ESR doesn't necessarily mean the capacitor is good, but an incorrect one means that it's bad).
Is 24.0 mfd a good test reading for a 24.5 mfd run capacitor with a multimeter?
That would depend on the tolerance of the capacitor. As the measured value is only about 2% below nominal and most capacitors have 10% or 20% tolerance it should be fine. However if it was a precision capacitor with for example 1% tolerance it would be bad.

How do you discharge high dc voltage capacitor?
When a capacitor is powered off in an energized circuit, the capacitor still stores a certain amount of electricity. When there are other loads or components in the circuit, they will slowly discharge, or they can be quickly discharged by short-circuiting with small resistors or wires (at low voltage). When the capacitor discharges, the two poles of the capacitor respectively carry a certain amount of charge, and the outside world and the capacitor form a closed loop (generally, the closed loop does not include a power supply). The excess electrons (negative charges) approach the positive electrode of the capacitor to form a current, so that the charges at both ends of the capacitor are neutralized. When the neutralization is completed, the electric field between the two electrodes of the capacitor disappears. However, this is in an ideal situation. The amount of terminal charge is exponentially neutralized towards zero, but not zero. Discharge requirements of capacitors After the capacitor is disconnected from the bus, it must be discharged through a discharge resistor or a special voltage transformer. Discharge should be performed between the lead wires of the capacitor and between the lead wires and the casing. The capacitor can be grounded after the capacitor is discharged. Before working on the capacitor, be sure to conduct a test discharge. This discharge is to place the discharge rod on the terminal of the lead wire of the capacitor for a period of time. Even if both sides of the capacitor device are grounded, in order to prevent residual charge on the capacitor, a test discharge must be performed, and each group of capacitors connected in parallel must be discharged. Special care should be taken when conducting inspection discharge of capacitors removed due to faults. Due to the damaged capacitor, the general grounding device may not function as a ground discharge due to a partial disconnection. If the capacitor device has an interlock device, it should be considered that only after the entire device is grounded, the small door of the capacitor bank protective fence can be opened.

What is the differencebetween a run capacitor and start capacitor?
The run capacitor is used when the load is functional while the start capacitor is used to produce the initial torque to drive the load.

How should I properly wire a dual run capacitor in my electrical system?
To properly wire a dual run capacitor in your electrical system, connect the common terminal to the compressor, the fan terminal to the fan motor, and the herm terminal to the start capacitor. Make sure to follow the manufacturer's instructions and safety precautions when wiring the capacitor.
How can I test a capacitor on an AC unit?
To test a capacitor on an AC unit, you can use a multimeter set to the capacitance setting. Disconnect the capacitor from the unit, discharge it, and then place the multimeter leads on the capacitor terminals. The reading should match the capacitance rating on the capacitor. If the reading is significantly lower, the capacitor may be faulty and in need of replacement.
How to test an AC capacitor with a multimeter?
To test an AC capacitor with a multimeter, first ensure the capacitor is discharged. Set the multimeter to the capacitance setting and touch the probes to the capacitor terminals. The reading should match the capacitor's rated value within a small margin of error. If the reading is significantly lower or higher, the capacitor may be faulty and needs to be replaced.
Should you get a reading between the herm and fan terminals on a dual capacitor?
No, you should not get a reading between the herm and fan terminals on a dual capacitor. The herm terminal is for the compressor and the fan terminal is for the fan motor. Reading between them could indicate a short or a faulty capacitor.
How can I test an AC capacitor to determine if it is functioning properly?
To test an AC capacitor, you can use a multimeter set to the capacitance setting. Disconnect the capacitor from the circuit, discharge it, and then connect the multimeter leads to the capacitor terminals. The reading should be close to the labeled capacitance value. If the reading is significantly lower or higher, the capacitor may be faulty.
How to test an AC capacitor with a digital multimeter?
To test an AC capacitor with a digital multimeter, set the multimeter to the capacitance setting. Disconnect the capacitor from the circuit and discharge it. Connect the multimeter leads to the capacitor terminals and read the capacitance value displayed on the multimeter screen. Compare this value to the rated capacitance of the capacitor to determine if it is functioning properly.
How can I use a digital multimeter to test a start capacitor?
To test a start capacitor using a digital multimeter, set the multimeter to the capacitance measurement mode. Disconnect the capacitor from the circuit and discharge it. Connect the multimeter leads to the capacitor terminals and read the capacitance value displayed on the multimeter. Compare this value to the rated capacitance of the capacitor to determine if it is functioning properly.

How do you test a vacuum capacitor?
To test a vacuum capacitor, you can use a multimeter to measure its capacitance and check for any signs of physical damage or leaks. You can also test for the continuity of the internal connections using an ohmmeter. Additionally, you can test the vacuum level within the capacitor by using specialized equipment designed for this purpose.

How do you test a capacitor using a multimeter?
A cheap multimeter can be used to test if a capacitor is burnt out. Connect one lead of the capacitor to one lead from a resistor (about 50k ohms). Set the multimeter to a high "ohms" setting and place the test leads on the remaining cap and resistor leads. The display should begin at 50 KOhms and then get higher and higher until it reads infinity/overload. A bad capacitor will either start at infinity/overload or start at 50KOhms and stay there. It won't tell you the ferad rating of the capacitor, but it will give a starting point to troubleshoot.
