Power to the cab

[Northern lights]

Found it. Someone had posted this site a while back and I saved it http://www.madelectrical.com/electri...evymain1.shtml . Came across it this morning and the simple diagram and explanation lead me right to the problem. The wire from the battery to the horn relay had fallen under the battery box and I had not seen it when I hooked the battery up. I knew it was something simple but didn't know where to look. I was looking on the wrong side of the truck.
