I need help, and don't have the time to look in the archives.  On the way to
work this morning I noticed the air conditioner blower was going slower and
slower.  I figured it was a bad resistor pack, blower motor bearings, or
something exotic that would take hours, if not days to trouble shoot.  When
I pull into the parking garage at work and go to turn on my lights -
nothing.  I open my sink drawer, it's a Westy, where I keep my multimeter,
and check the voltage at the cigarette lighter and get 7.5 volts.  I then
notice I have no lights on the dash to alert me to a charging problem.  Then
again, there may not be enough voltage, because my fuel ang temp. guage were
doing nothing.
My question.  Does the famous blue wire have anything to do with this?  I
have a spare alternator with me, doesn't everyone, which I can install, but if
it is just a wire I would rather just fix that.
Any information would be greatly appreciated.

Thanks,
Doug
