"Pulsing" voltage

[bossoj@rpi.edu (Joseph Charles Bossolini)]

Having just replaced the ground strap from the alternator to the engine
on my 82 4000 diesel, I noticed that the voltage meter in the car seems
to pulsate between 13 and 14 volts, with the pulsing increasing in speed
as the RPMs increase.  The meter reads a steady 14 volts at idle.  I have
charged the battery to full, replaced the ground and the hot lead to the
battery, but I suspect the voltage regulator is the problem.

Does anyone know of a cure?

Thanks in advance!
