I assume you meant you purchased the "resistor". Who did your purchase it from? Did the horn work before? Any pictures? It is such a simple part it should work. The voltage drop doesn't occur until there is current flowing so it should be 12 volts on both sides of the resistor without the current flowing. I assume you are wiring from a 12 source to the horn and then to the horn button as a ground to complete the circuit, is that correct?

The resistor I bought was from Mac's and "Restorer" was the name on the instructions supplied. I've seen it available from several different vendors. The horn is good and operates great using a 6v supply. I do have 12v (yellow wire) running to the resistor and the wire coming from the other side of the resistor going to the horn. The remaining wire (blue w/ white) is going through the horn button for ground, Checking it with a voltmeter, the voltage never drops when the horn button is pushed.
I was wondering if anyone had ever used one of there.

I use this as posted by others. Reasonable price.
