A capacitor may show an initial "short" or low resistance but then should charge until it''s resistance measures infinity. The leads of the capacitor should be disconnected so it''s out of the circuit when you make the check.

A run capacitor keeps a motor running by inducing a phase shift in the stators to help the rotor "grab" the next stator and turn. When a run capacitor goes bad, this phase shift does not occur and causes the motor to work harder, and in turn, overheat and destroy the bearings. What Is a Capacitor Rating?

In mechanically controlled variable capacitors, the distance between the plates, or the amount of plate surface area which overlaps, can be changed. The most common form arranges a group of semicircular metal plates on a rotary axis ("rotor") that are positioned in the gaps between a set of stationary plates ("stator") so that the area of overlap can be changed by rotating the axi…
