ever since i bought my 68 mustang awhile back the two horns have be terable. you can barely hear them driving and when your on the highway its like im not even hitting the horn. are they supposed to be like that or are they busted?

They should be loud. First pull them off and clean the bolt attachment point to make sure you get a good ground. Then give them a test. If no joy, then try disconnecting from the harness and hitting with a jumper wire straight from the battery. That will tell you if your horn is toast, or if you're dealing with a weak wiring system.

You may also need to adjust them, the back of each horn has a screw that closes the circuit to ground, adjusting the screw changes tension on the contact inside the horn and chages the voltage through the horn. They need a certain voltage range to work correctly, and this may be required if you recently made any changes to the voltage of your system(ie internally regulated alternator with a higher voltage, this is why I had to adjust mine). If you get someone to just sit on the horn while you adjust the screws you can set it so it's freakin loud. There's also an explanation of how to set them in the shop manual using a voltmeter I think

I just replaced both of my horns (the low pitch and the high pitch). They went from barely audible (which was quite embarrasing) to LOUD. I think I paid $12 for each of them. It could be the single best-bang-for-the-buck project I've ever done! Oh, and swapping them out was a total of 10 minutes.

knuckless,

I have a 1968 coupe too. I had boughthi and low pitch replacement horns for my car but did not end up needing them. If they end up being your problem, you can have themtwo for one plus shipping. I never opened them andhave beensitting ina box in my garage for over a year. email me let me know.
