“I’m going to show you how easy it is to detect everything we just did, plus you don’t have to know the wiring diagram, because the wiring diagram is right on here. So if you have a 24-pin connector, it tells you 24-pin connector. If this had two connectors on it, it would have say a 25 pin and a 24 pin right on the label and the wiring diagram is right here – 1 and 13, 2 and 14 and so on and so forth. The wiring diagram is right here and I don’t have to even think about it.
So, I go ahead and I plug in my cable, plug in the other end, and with the rotary switch I can quickly tell that pin #1 is in the right place and pin #13 is in the right place; pin #2 is in the right place, pin #14 is in the right place, #3 is in the right place, #14 is in the right place, now here I have a short (3:48). See how hard it was for me to test for a short (the old way)? Now here, we quickly found it. That’s also a short; now a mis-wire, it should be on pin #5 but it’s actually on pin #21. I was quickly able to do that with just a couple turns of the knob.
Most of the time what is missed is going to be that short. If I do see a short inside of a cable, if the inserts are good, I will cut it here and cut it here and get this cable out of manufacturing. They cannot use it. I will pitch it.”
Why You Should Throw Hot Runner Cables Away if You Find a Short
“I did have a company that came to me and said, “You know what Manny, the problem is probably going to be here and here, it’s probably still a good cable so we shouldn’t throw it away.” What I told him was if you are right, I am going to make you a brand new cable for free. This is what I’m going to do. I am going to take your cable, and I’m going to split it all the way down. And, when I opened it up, I could see that there were melted wires here, melted wires here and melted wires here. So if you do get a short, there is a potential for melting the wires inside.
With the ohm meter, I will tell you that 90% of the time (that’s a lot right?), the guy that’s ohming out that cable is not looking for shorts. He’s just looking for it making a contact. And, guess what, it’s going to make a contact but it could also be making contact with another wire. That’s where the short is.”
