How To Test A Starter Capacitor With A Multimeter. By taking the capacitors resistance we can determine whether the capacitor is good or bad. How to properly discharge and test a AC capacitor with a multimeter Start Capacitor Run Capacitor Dual Run CapacitorHVACR Heating Ventilation Air Con.
To get your readings right on an electrolytic capacitor connect the red probe to the positive terminal then the black to the negative terminal. If the capacitor is showing a charging reading on a multimeter and its going to discharge it to zero. How to test a capacitor with a digital multimeter After a capacitor has been fully discharged desolder it and remove it from the circuit.
To get your readings right on an electrolytic capacitor connect the red probe to the positive terminal then the black to the negative terminal.
This is the capacitor charging. Touch the meter leads to the corresponding leads on the capacitor red to positive and black to negative. That spark by the way tells you the capacitor probably isnt dead. However if you dont see a spark it doesnt mean the capacitor is bad.
