I need help with my install. I have created a schematic for it but am not sure if it is correct. I also am not sure what amp fuses to use, what relays, and what guage wiring. Please help with what you can!!
Don't use solenoid valves. You won't be able to modulate the pressure to get that 'real' train horn sound. You need a manual valve (cable/lever operated) to be able to barely 'crack' the valve, bringing on just a few of the five horns at first when you blow them.
Be sure to use a compressor relay that is only energized by the ignition key in the run position to feed B+ to the compressor. Don't want the compressor running all night. Also, use a proper pressure switch to cut power if the pressure goes past 120 psi.
Run all the horns from one air valve and the biggest plumbing you can fit. It's all about the sound.
Big reservoir or reservoirs - more air for more fun.
Be sure to use Nathan Air Chime K5LA horns if you can swing it - the Godfather of Train Horns.
