Air horn and radio/Alladin monitor

[moisheh]

One thing leads to another! As I had posted a few months ago my air horn stopped working. I did the test of the controller and it failed. They were out of stock so I bought a small horn button and will wire it to the air solenoid. I did some testing and there are 2 white wires connected to the solenoid. One tests as a ground the other is dead. I applied 12 volts to one of the solenoid terminals and nothing happened. Suddenly I realized that the unit has been sitting in my shop for months and there is no air!! Dummy!! I started the engine and was waiting for the air to build. I noticed that the radio and the monitor for the camera and Alladin were dead. I checked all the fuses in the front run bay. None were blown. I removed the dash cover and there were no other fuses. I pulled the upholstered panel by the driver's sat. I would have to get in there anyway to run a wire to the front run bay and then to the air solenoid. Monaco sometimes likes to hide fuses. Nothing. . I was through for the day but hooked up the wires to the air solenoid anyway. Went inside and the radio lit up!! Monitor is working. Somehow the ground to the the radio and monitor must be hooked up to that solenoid. I am stumped. That cannot be right! Any ideas??
