Horn Wires Polarity

Horn wires were soldered inside the conduit. When I disconnected I forgot to mark what was which and the wires are different colors out the horn that don't match the supply. Does it matter how they are connected?
 
If it is slow to react or sounds sluggish after connecting it up, reverse the connections and see if there is improvement to the tone. It certainly won't hurt it to connect it either way. Most folks don't sound the horn very long. On a motor driven horn, the motor will change its direction of rotation when the polarity is switched. When they get used to going one direction and wear in that way, it can sometimes change the tone when it goes the other way.
 
The horn uses a DC motor which can run or rotate either CW or CCW depending on the connections (+ or -). The horn will work either way.
 
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.
