Here is my latest Project in updating my Train Horn Compressor, I got a new compressor at Harbor Freight for $60, It fills up the tank in less then 1 minute compared to my old one that took like 8 minutes. The box contains a 14vdc 60 Amp Relay which is needed because the compressor draws 33 amps & i do not want to burn the car to the ground. When the compressor calls for air it triggers power on to the relay coil which kicks over the relay thus turning on the compressor, it uses 8 gauge wire , past wires i used melted and that was without a Relay, There is a switch also on the center console that feeds the main power to the relay coil in between the air pressure valve. Over all I am very pleased, I just ordered a new solenoid with 3/8 air fittings and rated at 300 psi from Hornblasters.com. Them cell phone talking green light no turnsignal using ppl will get it now !!

Now, get some compressors to slam that thing to the ground.
