Hi everybody I just joined today. Now for my problem which for some reason I can't figure out. I bought a train horn and compressor. I got the compressor up and running but the trouble is with making the horns work. They are 2 wires from the horn solenoid the directions say to ground one wire it didn't matter which one and run the other one to a toggle switch. Check. Then run from the battery and a inline fuse with a 40 amp fuse and tap into the wire ran to the switch. Now my problem is when I install the fuse the horn blows which have my neighbors a little unnnerved. I ran a ground wire from the other terminal of the switch to a good ground and it still does the same thing I was thinking I didn;t need a ground since it was grounded in the back. Do I need to run the ground wire form the horn solenoid up to switch too??

Ground one wire from the horn. hook the other horn wire to one side of the switch. Hook the other side of the switch to the battery with a fuse. Keep the fuse as close to the battery as possible. That should do it.
