The Cessna 120-140 Association Forum

Hello
I have a Voa 40 connected to a King 175 B Nav Com.
Interconnection is done by 4 wires.
Worked fine for years.
I lost indication. When wiring was inpected I found one cracked cable in Amphenol connector. Voa side.
I cannot make sure where it was soldered.
Looking for circuit but seems it is not in internet.
Thanks for your help.
Horacio

Horacio:

From an "Avionics Pins Out" disc showing the VOA40 connection to the Narco 12 series but I think the VOA40 pins out will give what you need:

VOA 40 P-101
Pin 1 OMNI/LOC SIG
2 - GROUND
4 - +14V ( Probably switched from the King 175B)
8 - VOR/LOC CONTROL

Hope this helps, if not, I can probably get the appropriate pins into the King 175B.

Best regards,

Big Edd

Thank you Big Edd.

That is what I need. Just the four wires pinout.

On the King Side I have no doubts. Install manual from Bendix King is in the public domain, and the wiring is not damaged.

Thanks again, and Happy New Year !
