How to know if a capacitor is dead?
Every attempt of the test should show similar result on the display for a good capacitor. If there is no change in the resistance in the further tests, the capacitor is dead. This method of testing the capacitor might not be accurate but can differentiate between a good and bad capacitors.
How to test a capacitor without a meter?

How to Test Capacitor without a Meter? If you don’t have a multimeter, you can still perform some basic tests such as: 1. Visual Inspection
How do you test a capacitor with a multimeter?
So let's start: A very good test you can do is to check a capacitor with your multimeter set on the ohmmeter setting. By taking the capacitor's resistance, we can determine whether the capacitor is good or bad. To do this test, We take the ohmmeter and place the probes across the leads of the capacitor.
How to check if a capacitor is faulty?
Swap the known good capacitor with the suspected one in the circuit. Power up the circuit and observe its behavior. If the circuit now functions correctly with the known good capacitor, it suggests that the suspected capacitor may be faulty. 3. Simple Circuit Test for Capacitors
How do you know if a capacitor is good?
If it is a little lower, it is still a good capacitor. However, if you read a significantly lower capacitance or none at all, this is a sure sign that the capacitor is defective and needs to be replaced. Checking the capacitance of a capacitor is a great test for determining whether a capacitor is good or not.
How do you know if a capacitor is open?
If there is no movement of the needle or the resistance always shows a higher value, the capacitor is an Open Capacitor. This test can be applied to both through hole and surface mount capacitors. The method described here is one of the oldest methods to test a capacitor and check whether it is a good one or a bad one.
