Train Horn

[DMAXNAZ]

I installed a seperate button for the horn, and an override switch for the compressor. It seems like these all seem to leak at some point and the compressor will kick in when your sleeping at night. Or who knows, if you have a good leak the compressor could drain your battery. I would just flip the override switch on every once and a while to see if the tank had air. If it fell below 90psi it would kick in then shut off at 145psi. Then I would just turn of the override switch again. Some of my buddy's trucks without the having an override switch would refill constsntly. I should add that there are all kinds of pressure switches to buy. On at 90psi worked good for me. Still got a loud blast with that much air.
