Thanks to everyone who submitted their recommendations on hooking up the
idiot light circuit for my alternator. I decided to try and hook up the red
LED that has the resistor already attached and covered with heat shrink that
I purchased from AutoZone.  Finn.....I followed your advice, hooked the
black wire to the L terminal on the alternator, and the red wire to the
ignition switch circuit.  Before starting the engine, the LED was a very
bright red. After starting the engine, no change....I flipped on the
alternator switch and the LED went to just a faint red glow....just enough
to barely notice that it is producing any light at all.  Tried it a few
times, and unless that remaining faint red glow is a problem, I am very
happy with the results. An unexpected benefit.... The faint red glow lets me
know the LED is OK during normal operations.  (Like I would know anything
about normal operations). Thanks again.   Paul Conner, the idiot wiring the
idiot light.
