[DML] Re: Bad Battery / Good Alternator

Again a collection of half correct things. :-(

It is attached to the housing but very easy to come by - you don't
need to open the complete housing, take off bearings and stuff like 
that. OK in old days the regulators were externally - that was 
because they were electromechanically built without transistors !
That was until the early 60s !!!

I still have my first alternator in my daily driver - 14 years old!
and yes it is a huuuuge difference between 40A and meanwhile around 
200A types that need liquid cooling !! Carbon brushes still wear
like they used to do back then, but back then we swapped them for 2-3 
bucks instead of replacing the whole unit as most people do today.
OK in the good old days everything was better...

Is there any real explanation for that ????
What do you mean with dead plates ? I had dead batteries in my car
before and I am still alive - and my voltage gauge still showed
13.8V when the engine was running at a bit higher speeds than idle !
(of course NOT with all the loads on that I could find !)
What are we discussing here ? Do we need to discuss basic high school
electricity laws ? Starting at Ohm's law ?

I get those emails sent from yahoo, I don't read them online, so
I have to delete them everyday - and with all that wrong or half
truth stuff they are as worthless as Viagra spam mails !
