[Elecraft] problem with K2, KAT100 and K2100PA combo

[Jay Rutherford]

Sorry to flog this poor horse once more. My XT90 AMASS connector failed due to not being completely inserted with the mate on a 52volt e-trike. It burned up one of the conductors inside the female plug.

I have never had a failure of an Anderson powerpole in many years of using them. It is easy to see when they are not completely connected.

Just to give a different perspective on the subject.

73,
