THC voltage check guide

I have a Hypertherm 45xp. I’m trying to troubleshoot a THC issue. On langmuir’s voltage check guide, it says to measure the DC voltage across the negative (torch) pin in the voltage divider port and the positive pin (work clamp). On the Razorwelds, those are the only two pins in the cnc port. Mine is Hypertherm, and there are seven pins in the cpc port. 3, 4, 5, 6, 12, 13, and 14. Does anybody know which of these I’m supposed to get my readings from? Can’t find anything in the Hypertherm manual. Thanks.

Someone will know, but I have the same cutter. What’s your issue?

Pin 5 & 6 are divided voltage. 6 is pos, 5 is neg.
