How To Test Run Capacitor. Turn the knob on your multimeter to capacitance mode. Multiply the ampere reading during the test by 23 to get the microfarads of the capacitor.
It will be the wire between. Turn the knob on your multimeter to capacitance mode. How To Test a Run Capacitor Under Load 1 - Check the capacitor data tag capacitance and - tolerance 2 - Measure start winding amps with an amp clamp between the capacitor and the start terminal 3 - Measure the voltage applied across the capacitor 4 - Multiply amps times 2652 and then divide by the voltage Across the capacitor 5 - Compare.
A very good test you can do is to check a capacitor with your multimeter set on the ohmmeter setting.
For a standard two-terminal run capacitor just touch the probes to the only two terminals that will be present. Knowing how to test a capacitor is likely out of range for most people. The only way to test a capacitor is to ohm it out. Capacitors with ratings above 70 microfarad uF are starting capacitors.
