I tried to wire up an external power supply to a coolpix camera to
take time lapse shots over a long period of time.  With the current
3.7 v Li-Ion battery it lasts about 4 hours taking a shot every 30
secs.

However it does not power up when connecting the "-" and "+" to a
3.6volt psu (which outputs 6.0v unloaded and does not drop when
connected to the camera).  I then realised that the "T" terminal
obviously used during battery discharge.  I assumed it was only used
during charge,

Any idea what this T terminal is for.  Can I just short it to the "-"
terminal.

The measurements currently are.

Between "-" and "+" 4.09V

Between "-" and "T" 0.0V

Between "T" and "+" 4.05 V

Also, this coolpix S200 has a failed flash function.  I remember there
was alot of discussion regarding using camera flashes.  Any pointers
on where to start with regard to repairing or should I just consider
it beyond economical repair (for a hobbiest).
