looking for guidance with electric train horns on MA
Dawg…. I’m assuming from the nature of your questions that something is not working, or you think it’s not working correctly.
I have a set of Hadleys on the roof of my DutchStar and a standard 12V vehicle horn as well.
The steering wheel center controls all horns. The 12V horn is always live. The Hadleys are only live when the panel Air Horn switch is set to ON. The panel switch only enables the air horns. The activation is solely controlled by the steering wheel center. With the Air Horn set to ON, the steering wheel center gives me both the air horns and the lighter horn together.
Hope this helps.
