My 95 Altima got rear-ended a few weeks ago by a Ford Explorer.  My
car's damage is fixable.  The driver side rear light was crushed along
with the sheet metal around it.  In fact, I have spent the past two
weekends to get the car back to a much nicer looking shape.  The only
remaining job is to repaint the damaged part.

However, I do have a little sticky problem with the electricity
system.  Since the accident, my dashboard metering light is gone and
so are all the meter functions.  I could jump start my Altima but it
won't stay in charge.  In a few engine startup, I can use up all the
power stored in the battery.  It may sound like either battery problem
or alternator problem.  However, battery was replaced about 6 months
ago.  Alternator was dealer-replaced from a brand new alternator about
6 years ago due to a faulty alternator.  The total milage on my Altima
is only 46K miles.

My questions:
1. Could it be loose wire somewhere that goes to the dashboard meters?
2. Is there a fuse box, or set of fuses, I can check for dashboard
meters?
3. Since the impact was not big, and there was no airbag deployment, I
don't think the accident caused the electricity failure.  Could it be
a shorted wire to cause burnt fuse somewhere?  My cursory checkup
under the hood does not find a single burnt fuse.  Are there other
fuses under dashboard?
4. Even if it was fuse problem, why would it impact alternator's
charging?
Thank you very much!
