WARNING about 4 core white cables from Ray

[plasmadrive]

So far I have had several in a batch of 200 that shorted internally.   The failure percentage is about 4-6%. (very high for cables). 

 

I haven't tested them all yet so I don't know the final number of failures.  Mostly it is the two pins that are internallly connected to the blue and brown wires.  On the cables I cut up the shorts all occured at the male end.   

 

I would recommend that if you have these and you received them within the last month or so, you might want to check them before putting any power to them:

I also have the 25' cables but have not tested them as of yet. 

 

I also ran across one that had an open connection.  I can live with open much better then shorted,  but obviously these are never tested after assembly.

 

I have used plenty of these cables in the past with no issue, but this batch has it's problems. 

 

I have informed Ray and he says he will look into it..  whatever that means..
