A shorted (low resistance) plug is VERY unusual, but you've obviously
found one. Usually a short will blow the fuse (or if it's internal to
the glow plug, the plug shortly will fail).
All the dash light NOT illuminating means is that the system needs to be
serviced. Usually it's an open plug, but not always.
