I have no vested interest in any of this, but I have a problem when statements are made that are patently wrong. Here is the basic formula I=E/R, with E being voltage., I is current, and R is resistance. Therefore, if E is low, then naturally I will also be low, and no current spike will occur.
I can only say with some confidence that a bad connection will not cause component failure, but a WRONG connection will.
