Problem when daisy chaining the ground wire

<< < (2/6) > >>

matsadona:
Are you 100% sure that you haven't connected the ground wire to any of the NO/NC pins by mistake (instead of the common pin)?

Generic Eric:
I've connected the wires to the wrong connector before.  I've also made crimps that didn't hold.  I've even changed out a switch.  Of things that are cheap in this, wire and crimps are among them.  I wouldn't spend to much time on it, if it isn't obvious now.  Sounds like getting close to time to recrimp.
 

Happy sleuthing.

dkersten:
One daisy chain ground I got was full of bad crimps, and would have shown the same kind of intermittent issues that the OP is having.  Meter from one end of the chain to the other to check resistance, if it is more than a few ohms (or no connection), you have bad crimps, whether it is hooked up wrong or not.  I was seeing something like 47 ohms even after fixing two completely breaks in the chain and found almost every crimp to be loose.  Once repairing I dropped the resistance from end to end down to about 2 ohms. 

matsadona:
Except from that I'm lazy, this is the reason why I stopped crimping in my projects. Soldering is the way to go for me nowadays :)

Sarver Systems:
I prefer to solder the factory-made crimps.
