Re: Horn Button Meltdown?
The Yellow-Green wire connects to a coil inside the relay. The other side of the coil connects to the Yellow-Blue wire. When the Yellow-Blue is grounded the coil is energized. You are measuring the voltage at the two sides of the coil, the difference is the voltage drop due to the resistance of the coil.
