I bought my Crossfire Pro about 4 months ago and, after some renovations and a few flooding issues I have finally assembled it. Once I got everything finished, I started to make my first cut and got the dreaded IHS error where it stayed green in FireControl and basically kept reporting an open circuit. I checked for electrical anomalies as suggested, but nothing was clicking. I traced every wire junction back to the head and it all seemed fine…until I noticed that the two copper terminals in the head assembly wouldn’t conduct across each other when touched together. I checked for a gap between them, but there was none. That triggered a random thought and I remembered that my German fencing swords had a wrapped copper wire with a resin coating underneath to prevent grounding in the blade.
After disassembling the head, I found two issues:
-
the screw for one of the IHS contacts was loose and wobbled alot, with the nut almost coming off of the back (in my case it was the black wire, or the terminal on the right from the rear of the head). I addressed this while having the head apart.
-
After disassembling the head all the way down to removing the wheels from the track, I scraped the copper terminals with the edge of a razor blade and sure enough, each produced a thin, semi-transparent flake of protective coating. Afte reassembling everything, it works like a champ!
I’m attaching pictures of the copper terminal, as well as some images from the reassembly process. This took about an hour and a half to do right and document. BE REALLY CAREFUL with the spring - you will have to move it in a way that looks like you’re going to warp it, but compressing it with a pair of small needle nosed pliers will prevent it from bending out of shape.
If you need any guidance on this, I’ll be glad to help by describing what I did. This definitely saved me time and money by not having to ship parts back and forth to LS to address what was ultimately about $.01 of protective coating that stopped everything from working.
