So, I did actually try that Will. What happened was when I hit the horn everything went dead and the horn didn’t do anything. I think it offsets the balance too much. I am positive this 6v horn works too.
Like I said, wiring is clean and wasn’t touched by anyone it seems. Maybe I just should drop the horn? Or try a new diode for the hell of it?
Not sure what that zener diode is actually rated at anyways
