"So Jeff, if your alternator cannot provide the current to drive the
headlamps where does the current come from."
It came from nowhere Andy. The engine stopped when the headlights were
switched on so nothing was required.
As far as I am concerned, the alternator provided sufficient current for
keeping the sparks coming (AFTER the battery was removed) and running
lights and a little more. Once demand exceeded that limit, it stalled. As
you said, it no longer had enough to provide the spark needed.
An alternator certainly could not provide the alleged 200 Amps or 300 Amps
usually required to turn an engine over, albeit drawn for only a very
short period to break the inertia of the engine.
"So where does the missing current come from to replenish the charge in
the
battery as the battery is "topping up" for the alternator, which will not
drive the headlamps?"
I am not quite sure that I understand that question Andy.
Missing current? What current is missing Andy? With the battery in
circuit, the battery provides all the power necessary whilst driving. Any
discharge is topped up by the alternator. A large discharge, when
everything is switched on, as it might be on a cold dark winter's night,
and it would take much longer to charge it back up to scratch. Certainly
NOT the 5 miles suggested by someone earlier either. Try starting a flat
battery by jump-starting it and then driving a mere 5 miles and trying to
start it again. I did so too frequently in my early years driving and a
lot more driving was required to gain enough charge in the battery to
start again without a jump. It was not always down to duff batteries or
bad charging either. If lights were accidentally left on, or similar, even
a good battery loses considerable charge if left for long periods.
"Does the car "dowse" for it?"
Was there some intended humour in that remark Andy? I merely see it as
unnecessary sarcasm when it was not even applicable. Why bring dowsing
into the subject? You obviously know nothing about dowsing and apparently
have an adverse opinion on it to come out with a remark such as that my
friend. Not called for and not on old man.
"Do the headlamp pixies provide it? I think we should be told as this
energy we can get from nowhere may be the solution to the world's energy
shortages."
I do not believe in pixies. Perhaps you do, but I do not. As I stated, the
engine stopped, so no "magic energy" was ever the case.
Take the battery out of the loop, as I explained, and the alternator could
only provide so much current. Then the engine stops.
Of course I WAS reminiscing about my early youth, some 30 to 40 years ago.
Perhaps magic alternators are the norm nowadays as technology has improved
considerably and my experience will therefore no longer be repeated. Let
us not start a war about it though as it is unproductive. I shall leave
you to have the last word on the subject Andy. Insults are non-productive.
