Bridgeport Magnescale Help Please

[bugnut]

So my milling machine is equipped with Sony Magnescales.

Recently when I turned on the digital readout the y axis scale started smoking. I quickly shut off the readout. I reset everything, looked it over carefully and tried it again and same thing. Since then I removed the scale from the machine to troubleshoot. image 1

I noted breakage where the connector installs on the aluminum housing and mates with the cable end. image 2 and 3 This is not from where it was smoking, I have now cleaned the EXTERIOR of the scale and looked hard for the cause of the smoke. The attachment, I believe with the reader head, is where the smoke was from. On examination the attachment where the wire enters the assembly was smokey. image 4 and 5

Since removal and cleanup I bench tested it, today twice and no smoke. I can find no readily seen issue.

So I am looking for help on a couple questions?

Any one have a similar experience?

Is it safe to disassemble further and insure the interior of the aluminum housing is clean?

I tried super glue and if did not work. Can someone tell me what the broken cable ends are and if the can be retrofit? image 2 & 3

Is there a way to disassemble the connector seen in image 4 & 5?

Please add anything you think I might do. Thanks in Advance.

You have a dead short somewhere, that's stating the obvious. But until you find it and repair it its going to be like a snake in the grass waiting to jump out again. Sorry I'm of no further help as I've not worked on a Magnescale before.

Do you have any ability to open the multipin connector (loosen strain relief compression nut and try to pull back the housing?
