Test Capacitor Without Desoldering (Incircuit Testing 2024)

Solution: Test a capacitor without desoldering it by using an ESR meter. No doubt, multimeter, or capacitor meters are used to measure capacitance. They just cannot be trusted to tell you if the capacitor is bad or good, whether it is outside or inside the circuit board. So, how can I test a bad in-circuit capacitor?
