Quote from: foakes on May 18, 2024, 05:04:49 AMThat looks like a capacitor, Joe —-I kinder understand the capacitor , as in start capacitor . When it was hooked up ,I got forward on one leg and reverse on the other leg . At first I though it might be a blocking diode for the park feature for the wipper . Also noted it was only high speed in both directions . Once removed than it became high on one leg and low on the other leg . I was looking at some picture to try to identify the closest I found was a Varistor ? This is the first for me with this surprize . And I didn't make magic smoke .
On a DC motor, it stores a charge of voltage very quickly —- and then releases it also just as quickly.
They are used in many electronic applications, and have been useful for years.
On a DC motor, it overcomes any variation speed or resistance in the rotation of the armatures —- to keep things steady and constant.
Best, Fred

The toggle switch on the side of the box is now a high and low speed . Low speed is slow enough , that I did not feel the need for a rheostat . I will put up a video tomorrow .
