I would recommend disconnecting one terminal of the cap first, then shorting it through a resistor applied to both terminals. The resistor limits the current flow, while disconnecting one side prevents you from accidentally shorting/improperly loading your power supply if its still hot or turns on without warning.
Hot melt glue the new capacitor to the top of the board, the jumpers should remain twisted. Tip1: If a capacitor has long enough leads exposed on the front side of the board, you can cut the capacitor off leaving the old leads and solder the new capacitor to the old leads. This method is even faster. See the last picture for an example.

This method is even faster. See the last picture for an example. Tip 2: You should replace all the electrolytic capacitors, not just the visibly bad ones.
Desolder Capacitor Leads: Apply the soldering iron to each lead of the faulty capacitor, melting the solder joints to facilitate removal. Use a desoldering pump or solder wick to remove excess solder and free the capacitor leads from the circuit board.
Lay the screwdriver across both terminals. Hold the capacitor upright with the posts pointed toward the ceiling, then bring the screwdriver over with the other hand and touch it to both posts at once to discharge the capacitor. You will hear and see the electric discharge in the form of a spark.
Grip the capacitor low on the base with one hand. You need to maintain total control over the capacitor while you discharge it, so pick it up low on the cylindrical body with your non-dominant hand. When you pick it up, make a “C” with your hand and fingers to grip it, keeping all of your fingers away from the top where the posts are.
If it's a hard brittle substance, try using a hammer and punch to dislodge the capacitor. If that doesn't work, try a bigger hammer! Do you need to keep the cap intact? If not, I would cut the leads, desolder them, and get pliers and gently roll the cap side to side to remove it.

In the question about damaged power supply I was told to use "a sharp utility knife", but it don''t cut that thing (is it epoxy?). Also tried old not-so-sharp scalpel (it can punch that things if pressed hard, but not cut). knife What other …
Then, safely remove the wires that connect the capacitor to the unit, taking note of their positioning for reinstallation. Use a wrench to loosen the screw or nut that secures the capacitor and gently remove it from its mounting bracket. Dispose of the old capacitor responsibly, following local regulations. By completing this step, you can ...
Step 3: Disconnect the Wires Use a screwdriver or pliers to remove the wires from the capacitor. Make a note of which wire goes where so you can reconnect them properly later. Step 4: Remove the Old Capacitor Once you''ve disconnected the wires, use a wrench to remove the mounting screw that holds the capacitor in place. Remove the old ...
When selecting appropriate capacitor discharge tools, it''s essential to ensure voltage and current ratings exceed maximum expected values by at least 2x and to choose tools with measurement resolution at least 10x finer than the smallest change to be measured. For oscilloscopes, the bandwidth should be at least 5x the highest frequency of interest in the …
I use insulated solid core copper wire to make jumpers, wires from cat 5 riser cable work well. Stranded wire is harder to work with. For larger capacitors use thicker wire (lower gauge) or put multiple cat 5 strands in parallel to each lead. Find and mark all the capacitor leads on the back side of the circuit with + and -.
Tip1: If a capacitor has long enough leads exposed on the front side of the board, you can cut the capacitor off leaving the old leads and solder the new capacitor to the old leads. This method …
Can I discharge a capacitor without any special tools? Yes, for low-voltage capacitors, an insulated screwdriver can be sufficient. For higher voltages, specialized tools …

How to remove Electrolytic Capacitors - 3 great Methods, is a clear, informative soldering tutorial showing the 3 best removal options for your SMD Electrolytic Capacitors....
Remove the Capacitor From the Device; A lot of times, the capacitor is typically located on the motherboard of the device it is in. To safely discharge the capacitor without damaging the motherboard, desolder it from its position. Be careful not …
Also, once discharged, short them with a croc clip lead because they spontaneously recharge themselves out of nowhere. Yes, without the set plugged in. Remember: SIDE S = Switch off I = Isolate (unplug the set) D = Discharge (discharge capacitors as above) E = Earth (short capacitors to prevent spontaneous recharging)
Disconnect Wires: Carefully disconnect the wires attached to the terminals of the bad capacitor. Note the polarity of the connections and label the wires if necessary to ensure correct reconnection later. Remove the Bad …
Capacitance, voltage ratings and polarity are explained. You can replace faulty caps on your circuit board and bring your electronics back to life! Example of a high quality replacement...
Step 2: Remove the capacitor''s housing and locate the schematic diagram. Step 3: If the schematic diagram is missing or unclear, use a multimeter to determine the capacitor''s terminals'' polarity. Tools and Equipment Needed: You''ll need the following tools and equipment to identify the capacitor''s wires and terminals:
You can discharge a capacitor with an insulated wire, that has been stripped on each end, by touching the two terminals as you would with a screwdriver. How safe it depends on the voltage; above 100V should be done with a discharge tool.
At audio frequencies that generally means you can either completely remove the part (preferred) or just disconnect one of the two leads. If someone writes "replace the capacitor with xxx" it means to remove the …

At audio frequencies that generally means you can either completely remove the part (preferred) or just disconnect one of the two leads. If someone writes "replace the capacitor with xxx" it means to remove the original capacitor and replace it with something like a capacitor that is of different value or has some other difference.
Just strip the ends of an insulated wire and short it. The repair issue is secondary to the valid issue of how to safely discharge the capacitor. This is ON-TOPIC.
Disconnect Wires: Carefully disconnect the wires attached to the terminals of the bad capacitor. Note the polarity of the connections and label the wires if necessary to ensure correct reconnection later. Remove the Bad Capacitor: Use a screwdriver or nut driver to remove any screws or brackets securing the bad capacitor in place. Once loosened ...
5. Remove the Old Capacitor. Once the wires are disconnected, carefully remove the old capacitor from its mounting position within the fan housing. Dispose of it properly, according to local regulations. 6. Install the New Capacitor. Take the new capacitor and position it in the same location where the old one was. Ensure it is securely mounted ...
