Challenger Horn

[Rob72]

Need a little help from the experts on this one

First, let me say that I am no mechanic, but know enough to make my way around the car

I've had my 1972 Challenger since 1999.  When I bought the car I was able to get an optional rim-blow wheel installed.  At the time I didn't know what it was but looked great inside the car.  The horn was working at the time (but not well).  Within the first month the horn stopped working, but I didn't worry.  Since I have completed a gradual restoration of the car (the dash and steering column were never removed).  Due to the increasing amount of bad drivers in my area I want to get my horn working again

I have taken a bettery to both horns and they work, there is power all the way from the firewall to the horns.  I did realize I was missing my horn relay (took it off very quickly when I was working on the interior and couldn't stand the door buzzer).  This was years ago, so got what looks like a good replacement from our Mopar dealer, still no noise

No one in my area knows about the Rim-blow wheel and it's options so I'm hoping someone can give me a tip or two on what I should be checking next.  Is it the relay? Wheel?

Thanks

There's 2-sides to this, the relay side which always has + power & receives a ground from the wheel to energize &  the horn side which is always grounded & gets + power from the relay.   Make sure you have good grounds.  You should hear the relay click when you press the wheel, if not there is a problem on that side. If you hear the click you need to check + power through the bulkhead connection & on through the harness to the horns.

A quick way to verify proper operation of your rimblow...

Remove your rimblow wheel, unplug the lead wire from the pigtail on your wheel and ground it against a bare metal area on your steering column. Your horn should blow. If it does, your problem is in the steering wheel. If your wheel is the problem, let me know and we'll go through a few more troubleshooting steps.
