Having problems with your 1987 Oldsmobile Cutlass Supreme ?

I have a 72 olds cutlass supreme.  I had the generator, voltage regulator and battery changed all together last month.  I had replaced each component seperately in the last 4 years, once for the generator and 2 times for the voltage regulator and battery.  I am having the generator light come on dimly, unless I park and accelerate, and in that case it only goes of momentarily.  I have just cleaned and replaced the grounding bolt that attaches to the engine block.  The only causal factor for this

Answers :

The alternator may have a bad diode in the circuitry.. I think it 2 or three; and one bad one would give a charge but not fully functional... I would test it for this condition.
Sounds to me like sticky brushes in the generator.
