Thanks. All parts are new except the steering wheel. I ordered another horn spring contact in case the new on I got is bad. Nothing looks warped on the steering wheel to my eye but I'm going to try to devise some sort of test rod to puit in where the horn contact spring goes and turn the wheel to see if it's making contact all the way around. Anyway, enough said. I'll just have to keep trouble shooting it. If I do figure it outI'll post my findings to hep anyone else with the problem.
I know on autos made late 60's the directional switch harness also carried the horn circuit. And the directional canceling cam had the horn contact ring built on top of that.
Now if your truck is like that as the steering wheel gets turned or shift levers move they could cause a slight movement of that harness. And if that harness is bad it can then make the horn intermittent.
