To get your readings right on an electrolytic capacitor connect the red probe to the positive terminal then the black to the negative terminal.

How to test motor capacitor with multimeter. Next take a photo or make a note of which wire connects to which terminal on the capacitor. Once the power supply is shut off you can use a screwdriver across the two terminals on the capacitor to short it and discharge the unit. To check your capacitor youll need a multimeter.

To check a capacitor with an ohm meter you must do two things. To test a capacitor with a multimeter discharge the capacitor set the multimeter to test for resistance then interpret the reading. To test a capacitor by dmm digital multimeter follow the steps given below.

Its usually easy to remove a start or run capacitor you simply unhook it from its harness and disconnect the wires. Set the knob on your digital multimeter to capacitance settings then connect the probes to the terminals of the capacitor. Digital meter will show some numbers for a second.

Connect the meter leads to the capacitor terminals. Make sure the capacitor is discharged. This will help to prevent shock.

The first is to remove the capacitor from the circuit. Since capacitors store voltage the multimeter is also capable of reading volts. Set the meter on ohm range set it at lease 1000ohm 1k.
