Rivco horns

[the bull]

I just installed a used set of rivco horns.  Had trouble getting them to sound.  Finally figured out that one must be blown.  When I plugged one off the other one worked.  It is loud, but I am not sure if this one will get damaged because the other one is plugged thus causing more air pressure in the one horn.  Also would it be louder if I replace the broken horn, or will it stay the same because only 1/2 of the air will go to each horn.  I think that the 2 horns will produce a different sound because they are different sizes.

Thanks in advance for all of the help that is always provided from the wonderful members on this board.

Do yo have an air compressor?   If so try low pressure and see if it works that way.  If it does but not good I was told to soak mine in mystery oil over night and that helped a little.  Did you replace the hose?  That was my other issue inside of hose was collapsing and not letting enough air thru.   Get a piece of line plug from compressor put splitter in and see of both work.  Back to blow gun and compressor if horn works low pressure its either compressor or hose.  Good luck

Rivco recomends blowing some WD40 through your horns once a year.  That might cure the problem.
