A short circuit here means that there is no resistance (impedance) between the two terminals of the shorted capacitor. The vertical wire drawn next to the vertical capacitor shorts the two terminals of the capacitor. …
The vertical wire drawn next to the vertical capacitor shorts the two terminals of the capacitor. Any current flowing through this circuit segment will flow through the vertical wire and completely bypass the vertical capacitor due to the short. This means you can ignore the shorted capacitor -- it has no effect on the circuit.
You can check this by measuring between the electrolytic capacitor negative pin and the mounting pad. You can still take direct continuity measurements across the capacitors. A short is a short. One final point to remember - these capacitors are almost always connected in parallel with other components in the circuit.
A short indicates that one or more of the devices on the circuit have failed short - not necessarily the capacitor. The most common failure mechanism for ceramic capacitors to fail short is mechanical stress causing the ceramic layers to crack and internally short out. Unless you dropped the assembly, I doubt the caps are bad.
This YouTube video shows that you can check SMD capacitors for being shorted using buzzer mode, by touching the ground of the electric board with the negative terminal while touching each side of the SMD capacitors with the positive terminal, the one that has both of its sides making a buzz is identified as shorted.
By having their shorted terminals, the voltage thereof is zero (more precisely, the potential difference between them), so that this element is not operational in the circuit, and can be removed for analysis. The other two capacitors are in series, hence that:
Connect the multimeter probes to the capacitor terminals, ensuring the correct polarity. The multimeter will display the capacitance value. Compare it to the labeled capacitance. A significant deviation indicates a bad capacitor. It will display OL if the capacitance value is higher than the measurement range or the capacitor is faulty.

2 · Open Circuit: If the bulb doesn''t light at all, the capacitor is likely open-circuited, blocking current flow. Short Circuit: If the bulb''s brightness is unchanged from direct connection to 220V, the capacitor may be short-circuited, allowing full current flow. This method is best for quick testing of high-voltage, high-capacitance ...

Safety Check: Before touching any components, double-check that the power source to the circuit is turned off to prevent any accidental charging of the capacitor. By using a multimeter to discharge a capacitor, you can safely monitor the voltage reduction until the capacitor is fully discharged, minimizing the risk of electric shock or damage to the capacitor …
Short circuits in capacitors can cause significant issues in circuits. To check for a short circuit using a digital multimeter: Set the multimeter to the continuity or resistance mode. Place the multimeter probes on the capacitor terminals. If the multimeter beeps or shows a low resistance value, the capacitor is short-circuited and needs replacement. Using an ESR Meter. …

Checking for Short Circuits. Short circuits in capacitors can cause significant issues in circuits. To check for a short circuit using a digital multimeter: Set the multimeter to …
Overall, faulty capacitors can cause serious problems, so it''s important to regularly test them for any signs of short circuit. By using a multimeter to check the resistance, inspecting the capacitor''s physical form, and ensuring the surrounding components are functioning correctly, you can make sure your circuit stays safe and efficient.
To test a circuit board for a short circuit check, you need to check the resistance between different points in the circuit. If a visual inspection doesn''t reveal any clues as to the location or cause of the short circuit, grab a …
To do so, you''ll need to short circuit the capacitor using a screwdriver or wire. Locate the capacitor and identify the terminals – these are the metal prongs or wires attached to the capacitor. Using a screwdriver or wire, touch both terminals together for a few seconds to discharge the energy.
