[DML] Re: Bad Battery / Good Alternator

["content22207" <brobertson@xxxxxxxxxxxx>]

Let me try to clear things up for you:

The regulator is very much inside the metal housing (in it's own
recess, but very much within the overall circular confines of the
unit). In the bad old days, regulators were completely separate from
the alternator housing, usually mounted to the firewall, a wheel well,
or some other engine compartment location. You replaced the regulator
without touching the alternator itself. Very few people replace
internal regulators these days (I don't know if parts houses even
carry internal regulators).

BTW: In the bad old days alternators lasted *MUCH* longer than they do
today. Not only were vehicle electrical demands negligible (40 amps
was quite common), but the alternators themselves simply were better
built. I also wonder what heat does to internal regulators. "One wire"
alternators are simple to install, but you seem to pay for that
simplicity with a shorter life span.

Regarding good alternators on bad batteries: If the plates inside a
battery are dead, but the alternator itself is good, it is not going
to produce 13.5 volts (typical charging nomenclature). I defy you to
produce charging voltage on a dead battery (not a battery that simply
needs specific gravity, but one that has bad plates).

BTW: If my eMails bother you that much, try not reading them. I do not
post anonymously. Reading my clearly identified messages, then
complaining that you do not like reading them, is a bit like a cow
standing on its tit then complaining that it hurts.
