And imperfect assembly is a mistake easily made. For the first year or so that
I owned the K3 I had the problem of intermittent DC, requiring fiddling with
the APP connectors until getting them positioned just right, only to have
intermittent connections again whenever the rig was moved. Then, having read
an earlier suggestion like the one Don just made, though skeptical that I could
possibly have assembled them incorrectly, I decided to give the blades an extra
shove from behind. Click. No more problems since.
I demur from saying whether I use solder or crimp. One can ruin friendships
very quickly by debating matters of religion or politics.

One of the reasons some have trouble with APP connectors is that they
have not been properly assembled.
If you look at the end of an APP and can see the spring finger as well
as the contact blade, it has not been properly assembled. Give the
contact blade a push from the wire side until the contact blade locks
over the spring finger.
If it will not lock, there may be solder on the contact blade preventing
it from being fully inserted - remove the contact blade and either cut
off the solder with a sharp knife or replace the contact blade.
