Hi Frank,

Too late. I just swapped HVA+ with HVB+. If this is a temperature and
humidity problem, it should follow the supply unless the current is
developing in the HV cable connectors. If the tripping goes away
altogether now, we can swap the cables back.

We ran under high temperature and humidity conditions at the AGS with only
a few trips.
