Bigdog, Jim, Carl, you guys hit the nail on the head.  The lower battery
cable post was rotating in the housing, and the insulation is all
deteriorated and torn.  I'll try to scrounge up some plastic of about the
right thickness and see if I can make a replacement insulator, shaped well
enough to keep that contact from rotating.  It's shaped like a rounded
rectangle, and the long sides are still flat enough that it might hold still
if I can fit it back into something tough and the right shape.  Definitely
learned my lesson about going easy on the wrench on these connections.
