I recently bought a DCS explorer to run a MTH GG1 with on my layout. I got it working, However, when the power is applied to the GG1, the horn just goes off non-stop. It is very, very loud so i do not wish to try testing it further.
It is a railking 4916 Pennsylvania 5-stripe 0-27/o gauge GG1 in that reddish brown color.
The box says it "accepts plug-in protosound systems" and when i opened up the engine, it did appear to have circuit boards for protosound.
I can send pictures, just ask.
If anyone could help me, that would be great! This is my first post here and i really don't know what to do with this problem.
