using a 12 volt system with the 6 volt horn

[briphaeton]

What I use is a Ohmite RESISTOR, 2 OHM, 100 WATT, ADJ TUBULAR, WIREWOUND, +-10% TOLERANCE.The Galco part number is D100K2ro.
It is a adjustable resister so you get adjust what sound you want from your horn. I found it in a old Restorer article? You have to make a simple bracket that mount on the inside frame rail so it's out of sight. Works great.

I saw the same in the ford mechanics handbook. The resister I have is called the "restorer" and when hooking it to the circuit, my horn just moans once. It does the same when hooked to a 12v power supply. The horn works as it should when using a 6v system. I'm assuming my resistor is not working.
I'm going to try the one you mentioned.
Thanks

I would guess the 12 volt power supply is not putting out enough amps to blow the horn.
