Y-harness question

       Remove this ad - become a site supporter!
I always make up my own servo extensions, but now i want to make up my own Y harness to power aileron servos in the upper wing of a biplane. Will it work if i just connect the 3 red wires together, the 3 black wires, and the 3 white wires? Is that all a y harness is? I know you can get kits to make up extensions with a y in them that include an amplifier (made by ACE), but I don't really need that.

Yessir. Just go ahead, join up the identical colours, solder them together and cover with insulation.

It will work fine. Have done that myself numerous times.

If you disect a commercial y-harness, that's what you'll find inside.

You'd want an amplifier or noise trap if you were using a very long lead. Of course, you'd also want a heavier guage wire too - not the skinny stuff.

You can use the telephone patch cord wire for making your extension, match the color of each wire to your connectors work like a charm. Been making mine for years works well even length is not an issue.

Thanks to both of you...I'm glad the thread did not turn into another arguement about soldering the wires Vs. crimping.

You want to start it again
For mine I have bought a small assortment of shrinkwrap for making my own. I connect the each different colour and shrinkwrap. Then I put a shrinkwrap cover over the three pieces extending past the others a touch. Makes a very neat installation with no stress.
If you have a Princess auto near they have a supply of lite wrap and are fairly reasonable. The 1/8" does the small wires and 5/16 will go over to finish. I shrink my deans plugs also with the outer cover over the 3 pins up to the plug.
