<VV> Alt light glows on LM

[Charles Morgan]

Ewell, I think (but am not positive) that this is what's going on:  Look at 
Fig 2c, page 6Y-5 of the 65 manual.  With the ignition on, one side of the 
light is connected to the battery.  In order for the light to light up, the 
other side must have a ground return path.  It gets that path when the 
voltage regulator upper contacts are closed.  When the voltage regulator 
relay is operating normally, those contacts are being continually opened 
and closed.  So the light is being constantly turned on and off--hence the 
faint glow.  The amount of glow is dependent upon the regulator setting and 
probably upon the bulb itself.  (BTW, the "resistor" shown directly above 
the light is really a resistance wire--the 24AWG brown wire shown in the 
upper right hand corner of the schematic on page 12-25.)
