When needing to put multiple wires to a single Faston type connector... do you butt splice multiple wires then use single lead to Faston spade or bring multiple wires into the Faston female connector and crimp? Thanks for indulging me...

Two, three or maybe four (depends on the wire size), and I'll put them all in a single connector. If they don't fit, I like to splice the wires into a single lead. But again, it depends on the size of the wires and their purpose. Six 20AWG wires supplying devices that are on all the time probably wouldn't work well spliced into a single 20AWG wire. But something like ground wires going to momentary switches would be okay.

This is the kind of stuff that makes my head explode. :( You're saying the signal is carried by the thing that is not supposed to conduct electricity? And I'm not doubting you. It's just that makes as much sense (to me) as my car battery being jammed full of AAA's.

Don Johnson The signal (which is obviously the important stuff) is DRIVEN by the "wave guide" which is the metal parts, but transmitted inside the wave guide...which is the insulation. It turns out that the wave velocity is exactly the same as the speed of light inside the insulating material-- Vacuum, Teflon or PE for example. I point this out to make sure that builders understand the reason for proper termination (which includes joints) of the coaxial cable. I can't be "pig-tailed" at high frequencies without enormous loss of signal strength. At low frequencies (like audio) it just doesn't matter. Electricity is strange. Please read my "Dabbling with Electricity". -------- Eric M.

It's actually full of AA's. There are two of these... http://www.youtube.com/watch?v=nzgDffMcsUU ...in every 12V car battery. And every AA is actually a stack of coin cells in a plastic wrapper! ;-) Eric do not archive On Aug 5, 2015, at 6:13 PM, "donjohnston" wrote: > It's just that makes as much sense (to me) as my car battery being jammed f ull of AAA's.
