Just resoldered mine _again_ last night. Symptom: boost maxing at 1.4
instead of 1.8. It seems that the outermost WOT connection is
the first to go. It was the one that had cracked in Pat Martin's switch
that I fixed a couple of days ago. I guess the temperature cycling
is a big contributor to this connection cracking.
On the repair. I don't think cleaning the connection and resoldering is
sufficient. Next time, I'm going to put a piece of wire around it
too in order to make it mechanically secure.
Orin.
