Anyone ever built a Socapex tester ?

I found an box, a male and a female socapex connector, and thought it would be useful to built a socapex tester..

Probably just something with 7 buttons and LEDs for each lines, in order to see if it's all in order and if there is a short.

Anyone of you ever made one ?

Just looking around if some ideas may be added to mine.

thanks

Here is how one guy built one:

There is the one made by LEX. I think you hot up the circuits and check what is displayed. It looks like you could build it yourself with many neon lamps and much patience.

Yes, I have built many many. And or provided Stainless Steel parts to those making them for me in better - less wear resistant fittings for those I don't have time to build. Next problem is often the dropped tester, where the often dial switch gets broken - so safety handles so as to protect that switch lever which once dropped on can break the switch.

What is not done at this point in a Soco tester is a electronic version.

Is there a high resistance short between conductors? Normal testers will at best slightly light up a indicator lamp in detecting this, but possibly not in a noticeable amount. No warning buzzer for a short should also be for one be flipping thru circuits in "checking" faster than they are looking for a problem. This per the flip the switch dial a wire version. Other versions on the market I am sure. But yes I have built many testers for Soco over +20 years.

Tools for Stagecraft and TMB amongst other testers with ways to do this in live power or before plugging it in seemingly.

Main question, seven position switch, perspectively has a "off" and all six circuits for continuity between the circuits. In theory such a thing would also light up to other circuits shorted to if shorted. What about a short to ground?

Pin one in testing a circuit, needs to test to all 14 or 19 wires for both continuity between pin 1 and pin 1, and all other 19 other pins for a short. As above, a high resistance short often will not be detected by way of just plain obserable resistance from indicator lights. Also, it doesn't "idiot proof" someone just spinning thru the dial in testing the cable without looking for a "fault/short." And again, most multi-position switches, are drop sensitive - meaning if you drop the tester off the table and it falls on the switch lever - it's broken. So you have to protect that rotary dial switch. This assuming a rotary switch tester type.

Lex tester I did not try, TMB in-line did try and not a fan of. If testing a cable, it should be before testing in live voltage testing to see if a problem of.

Next problem for my past testers in being non-line voltage testing... people line voltage usage of them. Ciruit protection in this conplex tester, a good thing in otherwise blowing it up, this with the battery chargers to it etc.

Overall, you need to test all conductors in referenece to another during testing. The Lex might do this, but am I seeing it needs live power in not reading into it? Short to ground? Best test of cable is before it's plugged into live power. Electronically testing the cable so it self tests see's all conductors in relation to each other would be quickest and safest. TBA invented.

I built a fox-hound type of tester out of some old connectors and BUD boxes. It was a lot of fiddling... But it worked.

Two types you can build both fairly easy - one tester for pin to pin continuity - real simple ., a battery 19 diodes , 19 LEDs -
The second can test under voltage, little trickier and for liability since it’s putting A/C in shop people’s hands I would use a commercial tester.
don’t forget the threads on the locking rings they get damaged A LOT !
