Hi guys,
Seeking some advice on how best to repair a missing pin on a Trimble 7-pin LEMO cable on a cow-bell external battery.?ÿ
Not sure how the pin got broken, but it doesn't either provide power or charge now. What are my options, replace the head? replace the whole cable? Is changing either a terribly complicated undertaking?
Any advice would be greatly appreciated.

I have been using Trimble gear for 34 years. I have never tried to fix a broken pin, I just buy a new cable. I buy from Western States Cabling. My opinion is that it appears to me difficult to fix, and I wouldn't want it to fail at a time when I really need it, so buying a new cable is seemingly worth it.?ÿ

You also need to locate the broken pin, it is most likely in a socket of the connector on your receiver or your charger.
Make sure you do not try to insert a plug into a connector containing a broken pin - that can really mess up things.
Instructions for removing a broken pin from a socket are found in the attached file.

I'd take John's advice and replace the cable.?ÿ The battery end is pretty straightforward, usually 2 female blade (push-on) connectors, so it's an easy install.?ÿ Just remove the screws around the battery case perimeter and pull the case apart, then you can R&R the cable.
I've soldered up a couple of LEMO connectors, but it's not an easy task, unless (and even then, only maybe) you do a lot of them.
Only too true. You need a small bit on the iron AND a steady hand. Don't try it unless yuo are confident. I shan't ask how you managed to break it - that takes some doing!
@glenn-borkenhagen this is incredibly valuable advice and guidance! Thank you!!!
Thanks very much gents, I kind of knew this would be the way to go, but wondered if there was maybe some wizardry that I wasn't aware of.

Have a great holiday!
Before i discovered Western States Cable I had saved and disassembled/rebuilt over 100 and was able to do so by my previous work in electronics and owning MetCal soldering system.
I even built an end to end lemo connector cable tester for all of the cablbes that had one or two conductors broken and needed to be retired.
Fun times.
