I'm not sure I understand what you mean by your first sentence... by meter
you mean the guage on the console or some
external volt meter. What is the diode and where is it. I think the voltage
regulator is in the altenator isnt it?
another piece of information... when I turn on the AC, the volt meter in the
dash goes down a full letter, From the "O" to "R"
in the word NORM...
So would that confirm the altenator? and should I take care of this soon?
Quite possibly. Turning on headlights probably does the same thing... Sounds
like it's out of your scope, but if you can take the alternator out, just
about any parts store will test it for you. Or simply go to your trusted
mechanic. Alternator replacement is not exactly brain surgery.
Is this the original alternator on this 19 year old vehicle? If so, it has
already served about three times its expected life.
Should you take care of this soon? Well, if you don't mind stalling in a
strange neighborhood in the middle of the night and have good towing
insurance, perhaps not...
