This shows the variation of the ripple voltage at one of the power supply filter bank connections. When the wire was wiggled the ripple voltage noticeably changed shown by the faint yellow. The crimp on the quick disconnect terminals seemed to be the problem. Putting the scope on the exposed wire shows different ripple than the terminal. I re-crimped the terminals and tightened them and the ripple stayed at the low level when the wire was wiggled.
