gene did you consider this
*DIM ALTERNATOR LIGHT - FUSE-*
There is one other condition that can cause the symptom of a dimly lit
idiot lamp. A GMCer replaced his alternator, and still had the dim glow
problem. He checked a diode that is supposed to eliminate this on some
production models. NO luck. He then discovered that his* 10 AMP dash
instrument gauge fuse was blown*. The fuse provides 12 volts to one side
of that lamp and if it is blown it does not have 12 volts there. When the
alternator starts putting out 15 volts there is a differential 15 - 0 and
it gets an indication. Replace the fuse (or check wiring and grounds to
make sure you have 11.5 to 12 volts at the lamp and the glow should cease,
except when the alternator is not putting out 15 volts, which is the way it
is supposed to work. It was reported in GMCMN in March 98 page 5. (John
