Power cable shutting amp down


I just put in a JPS Power AC+ and it seems to be overheating the amp. I've swapped in the Shunyata Python and that does not do this. I've put the JPS on the preamp when I do this?

Anyone heard of this behavior.... stock cable seems fine. You think this is a bad cable?

I found my house ground is not connected to the grounding rod. I am going to connect this back up. Must have been messed up by a utility guy checking the meters. Oof. Hope this is the fix.
ground actually was attached, just had to tighten the clamp... I don't think this is it.
Problem seems to be found... One of my somewhat lengthy runs of Kimber 8TC is bad. I guess retermination is the answer. Tried it with another amp/preamp and that seemed to be it.
