Does the horn work when the H lead of the relay is connected directly to ground? (bypassing the wire in the column and horn button)

He is cooking the relays. The only way that could be happening is if it was connected it as Described in post 10. He says the horn/s are working if power is fed directly to them.

If youre frying relays, might be a problem with the voltage regulator.

Go back and read his initial and subsequent posts. The only way to cook the relay would be to over volt it. And by the time voltage was high enough to do that you would cook every light bulb in the truck. And regardless the horn relay is fed from the Bat + it is just tapped at the VR. The VR could go completely sideways and it would not affect the horn relay doubly so since the battery would act as a buffer.
Now if the relay was not tapped on to the correct terminal at the VR that could pose some issues.
