Don't monkey around with a bad power cable. If you do not have tight
(low resistance) connections capable of carrying the full current, they
will overheat and can be a source of a fire.
My recommendation is to replace the APP connector with another (or buy
an assembled cable).
You *may* be able to remove the contact blade giving problems from the
housing by itself and replace that contact blade.
To release the contact blade from the spring finger, put a slender
tipped screwdriver between the contact blade and the spring finger
beneath it and pull (or push) the contact blade back until it clears the
spring finger, then pull it out of the housing. Download the XV50, 144,
222 Assembly manual from the Elecraft website and look at figure 29 on
page 37 for a good cutaway diagram of a properly assembled APP
connector. Page 38 of that manual also shows how the tip of the APP
connector should look when the contact blade has been fully inserted.
Do *not* try to re-use the contact blade. If you do not have any, you
can order a new one from Elecraft. The part number for the contact
blade is E620062 - APP Connector crimp pin.
If you need to replace the housings as well, the red one is Elecraft p/n
E620059 and the black one is p/n E620060. You will need 2 contact
blades if you are assembling a complete connector. You can order 15 amp
APP connector sets from other sources as well.
Alternately, you can order the pre-assembled power cable with an APP
connector at one end and #12 ring lugs at the other from Elecraft p/n
KPCA-F.
If you do not have the proper Powerpole crimping tool, do *not* crimp
with an alternate tool. Instead solder the wire into the contact
blades. Be careful not to get any solder on the front surface of the
contact blade because that will prevent proper insertion of the blade
into the housing.

How are they re-useable once they're crimped?
I guess you could maybe pry the crimp apart. (??)
