I have a '51 1/2 ton burb with the original horn. Recently the horn has become quite temperamental, sometimes it toots, sometimes it don't. The connections are all good, and I believe the horn button is good.
I fiddled with the adjustment screw on the back of the horn a bit, (not that I know what the heck it actually does) and no change. Pushing on the horn button (with the truck off) would produce no sound, but when the button was released, a faint peep or pop could be heard.
Today when I was driving along, I pushed the button and the horn tooted. At idle it would not. So now I'm thinking that this is voltage related. When the truck is off or at idle, horn will not toot. When I'm running down the road with a good 7.2 volts or so from the genny, horn will toot.
Or could this somehow be vibration related?
Any of you fellas know what the problem might be here? is it possible to R&R the horn?
Thanks,
Kurt
