Thanks Ken. I don't want to pop for the manual unless the damage is
failrly limited. Obviously with +13.8 applied to both the high side
and ground most components were not stressed. The question is what
that jumper inside the Jones plug that got connected to the low side
of the supply is connected to inside the rig. The smell of the smoke
was characteristic of burnt circuit board, and there was a fair amount
of visible smoke.
