Guten Morgen,

the motor is a series connection type. The collector and field winding are connected in series. Therefore, as already written at the beginning of these articles, the direction of rotation is always the same, no matter where + or - are connected. (It's the same with the starter motor.)

Since the "Waltons" is used only rarely and for a short time, I occasionally let it run for several minutes in the distance outside of people.

In addition, I switched a powerful current relay (25 A) with thick cables in between the battery and horn connector and one on the ground area.
