[DML] Re: Bad Battery / Good Alternator

Out here in the real world, batteries wear out. There comes a point at
which they are not going to produce a charge, no matter what the
plates are immersed in, no matter what kind of charging voltage you
run into them.

When that happens, an alternator simply will not put out. The
alternator depends upon the negative side of the electrical system to
recharge the positive. No electrons on the negative post, no electrons
into the alternator, nothing out the other end.

I've got an ancient dead battery here at the house if you'd like to
stop by and prove me wrong.

BTW: Ford was still using externally regulated alternators in 1980.
BBTW: My first daily driver is 27 years old (on its second alternator
BBBTW: You may want to add my email address to your client's spam filter.
