Alright. Been a while since I've worked on this one, but I'm back at it now.
The current problem is that depressing the horn button causes sparks to fly at the horn button, if one of the following is true:
1. the horn relay is in
2. i've jumpered sockets 1 and 2 where the horn relay goes.
I'm now scratching my head at this one. In scenario #2 above, according to the manual, if the horn relay is bad, the horn should sound; if it doesn't, my button/wiring is bad. But it didn't say anything about sparks...
