Air Horn Dying

[jstinson]

I have an FIAMM 12V air horn hooked to the dash horn button. The 2 flutes and air compressor are mounted in the front left wheel well. When I press the dash button the compressor groans and the horns sound but just barely. Could this be a ground problem? I checked the wires and they seem fine. Also there is a small cube relay looking thing attached to the wheel well labeled: FIAMM 12V 30 amp, so I'm guessing this relay could be a problem.

Should I replace the entire setup?

If it works at all, it is not the relay.

Could be ground or something else. Maybe, try an alligator clip extra ground wire and see if it helps.

Compressor perhaps? Take it out and bench test it all.

I have a few FIAMM horns on my cars. The compressor's crap the bed over time. Buy a new setup to get a new compressor. They are very cheaply made, but man I love the sound of them.

Has it been oiled regularly ?
