I bought one of the AeroElectic ground bus bars, which is a 37 pin connector with all of the pins on one side soldered together. The items that need a ground get pinned into the other side of the connector, along with 5 20 AWG wires that go to the airframe ground. Instead of the five 20 AWG wires, they suggest you solder two 14 AWG wired to the back where all the pins are soldered together. Since one side is all connected each item can find a route through the 5 airframe ground wires.
Now the question. The radios use 18 AWG wires for power and ground. It would be nice to use the same ground bus but how does one do this (18 AWG wire does not fit into the D-Sub pin and I believe they are rated at only 5 amps).
Then I had the idea, could you "Y" the 18 AWG ground wire into two 20 AWG wires that each get pinned to the ground connector? This seems to be how the ground bus works, all items that need ground go to the bus (connector) then the ground current is carried by the 5 wires to the airframe.
My idea is to solder a length to 20 AWG wire from the loop end to the 18 AWG wire and cover with heat shrink.
Thanks for any inputs.
