faulty horn 75 series troopy (1 Viewer)

[boo boo]

when I am having a mild attack of road rage and hit the horn I can hear it through the radio.It happens more often in the rain. Can anyone help. I have looked for an obvious short, but cannot find one.

I could be wrong, but I am not sure that this is the right section for a question about a troopie, but go throught the wiring and the button with a multi meter and see what you find.
