Back Up System Help

[Jeff Miller]

By +12v/Gnd I meant either +12v or Gnd. Most likely the switch is
made by +12, Gnd, or +5v.

+5v is used often in logic circuits, it would be created in the
camera. If +5v is not needed inside the camera, it would not output
+5v, and then the most likely (IMO) signal would be +12v.

For logic/semiconductor circuits it is unlikely that a 5amp fuse will
protect it from a dead-short. Something like 5ma or less (fast-blow)
might (.005a). Your odds are good IMO, but not 100%.
