Minelab Battery Charger Ikelite Adaptor for the Excalibur repair or replace?

[RustyGold]

I noticed my pod batteries not charging overnight so I tested the output of the charger at the Ikelite pins and no reading.
the charger's connector end had a 4volt output. I'm not sure if that is as it should be but ordered a new charger anyway.
the Ikelite adapter's female end, for the charger, came completely off the adapter so it was faulty.
My question is can these Ikelite adapters be taken apart and resoldered/repaired? I do see two small screws in the adapter.
Or is it best to buy a new one at $75.00 which is very expensive.
My apologies if this has been covered before!
Thank you!

I guess it's time to replace!
