Mike,

There is no need to chastise yourself simply because you mis-read 
the original question. You were trying to be helpful.

I believe the nature of this list allows us to post our opinions,
and those that read the opinions should remember how much the reader
paid for the opinion. 

I'm going to check the alternator and voltage regulator tonight.
It looks like one of these is suspect, hopefully not the alternator.

I've not seen this before.

Hence, the alternator and voltage regulator check.

Ok, maybe just this time, but don't let it stop you from adding your
comments in the future.
