First, was the tank empty when the batteries were dead? Could you have run the compressor for hours & hours? Because No relay or solenoid should be able to consume enough of the batteries reserves to kill them...
Maybe this is unrelated to the horns?
Also, isn't the horn sw, in the wheel, one that supplies Ground? (I wired mine differently, through a relay, at the wire going to the electric horn so I could switch between them)
