– connect a tester to the Faston terminals of the capacitor; if the
reading is roughly 10% higher than the rated capacity shown
on the capacitor, it means that the capacitor is damaged.

The value shown in the figure refers to a 4 μF capacitor and is
purely indicative. Please refer to the characteristics of the capa-
