I installed a second horn and relay on my VMC Speedster today, but when I tested my installation I discovered the horns remained activated even after releasing the horn button. Turning off the ignition was the only way to silence them.
After searching this forum I discovered that member Jon T had a similar problem and that the root cause was a ground fault in the horn wiring. However, it appears that the fault was never located.
So does anyone have suggestions on where to look for such a ground fault in the horn wiring?
