In case that happens again and it’s not fully destroyed like in the first post from last year, don’t try to fully repair it. Just get it working by either resoldering, or cut off the connector and solder direct to the deck cable, or even just twist the wires together if you have to, and zip-tie everything to the leg on the side of the spool as a strain relief until you get time to repair it proper. Don’t try to screw it back in because it will cause more problems.
When you do go to repair it, that broken end is soldered/installed first, but it’s all pretty self-explanatory when you’re holding the slipring assembly and you remove everything. The two halves of the slipring pull apart by hand. Normally, you may need to push the center of the Binder bulkhead to allow air in, otherwise you’re pulling on a vacuum when you pull the two halves apart, but they should pull right apart with a broken one, just a little o-ring resistance for the weather sealing. Do it carefully so you don’t rip in half like a gorilla, because you’ll want to see how the wires lay inside.
