Gear working horn

[Christopher Cotton]

Would any body know of a gear worning horn STC for the
Comanche preferably one that works off of the Manafold pressure.

Thought all Comanches had one that works off the throttle as our Twin Comanche's does.

The gear warning horn definitely comes from the throttle cable position switch. It should come on when the gear is up and the throttle is pulled back to achieve approximately 10-12 inch Hg of manifold pressure. Just like a pressure switch directly on the manifold. This will also result in about 2000-2200 RPM. The switch, I believe, is adjusted on the ground by setting a gap spacing on the switch and a landmark. Check the Comanche Service Manual for this setting.

Can anyone please tell me where in the PA-24 illustrated parts catalog I can find the Gear Up Warning "horn" (Buzzer, noise maker)? I see it in the wiring diagram (service manual), but can't find it in the parts catalog.
