All you need to test the alternator output is a voltmeter.  But if it were 
your charging system, everything else would be dim also.

I had the same problem years ago with my `67 B (and still do).  Replacing 
the dash lights rheostat made no difference.  Then, I had my tach 
recalibrated and refurbished and it was brighter than the other gauges for 
a few years.  I suspect that the plastic light diffuser surrounding the 
face of the gauge becomes opaque with time.  The diffuser to my fuel gauge
has a hole in it and sends a beam of bright light across the face of the
gauge so I know it's not that the bulbs are dim.
