Hi Dick,
Thank you for reading my offering. However, it seems that more than one
has had a problem understanding that which I wrote. Hmm. Perhaps I was not
clear enough, although I though that I was quite clear. My previous
offering was merely of an experience SOLELY concerned with a car running,
then stalling when demand was too high for the alternator to provide more
current, with NO battery. How else could I have written my statement I
wonder? It seemed plain enough to myself.

My apologies if I have confused you or any others Dick. That was certainly
not my intention. I always endeavour to write as plainly as I can,
although like many, I can transpose letters, miss the odd letter, or even
word out, (It's this darned keyboard ;) ) and make the odd "unclear"
statement.
As for "de-dowse you"! Hi. As you say, "impossible". I am going out
dowsing locally again in an hour or two so I cannot spend too much time on
this as more important things await my attention.
First of all, that experiment was over 30 years ago. Modern technology
will have provided alternators which provide much more power (Current)
than those earlier models. Indeed I noted that another UK writer (Sorry
old man, but I have forgotten your call-sign ? but thank you for providing
the corroboration of to my earlier comment, repeated again in my previous
sentence.
Second. I was ONLY concerned with the running of the car + any electrics
WITHOUT the battery. What the battery provides in normal running is
obvious and should not need to be explained to anyone familiar with such.
It was of no interest to the experiment.
Again. Basically, once the car was started, (It was an Austin Maxi 1800cc
as I recall) the car ran with NO problem, without any other electricals
running. Then I started to experiment. The side-lights were switched on
and little difference was detected, (Perhaps an increased "humming" was
detectable :) ). Once I switched the headlights on, the engine stopped.
Repeating this experiment several times to ensure that it was no error,
even with high revs, the engine would stall. It was apparent that the
amount of current drawn by the headlights was too much for the alternator
to provide a spark to the ignition AND the high ampage (30 Amps?)
necessary to use the headlights. it was as I had suspected.
It was also apparent that any "overload problems" or "cut-offs" or
whatever in the alternator would also play their part.
I am well aware that the battery provides ALL the current necessary to
start a car. Allegedly 200 to 300 Amps, more with heavy vehicles. The
battery provides ALL of the electrics in the car. Breaking the intitial
inertia of a heavy and stationary engine, increased greatly by freezing
conditions etc. and physically turning that engine fast enough to start
MUST, and does, take an enormous surge of amperage for a brief period of
time. However, the battery can recover quite well when running. Unless the
plates or the charging system are faulty!
I am also aware of the fact that when too much current is drawn from the
battery, the alternator tops it up to normality again. More when it is
flatter, the current tailing off to a trickle as it is charged more fully.
That is what an alternator is for. To ensure that the power source of a
vehicle is kept charged to the full and keeps the battery at full charge.
Now I do not quite know what Andy was trying to say. By his questions, he
appeared to think that I was writing about a car WITH a battery. I was
not. It was WITHOUT a battery. Once connected, it immediately changes the
circumstances and is of no consequence to my first writing on the subject.
Have I covered this (Again) sufficiently to understand now Dick? I hope
so. What was just a quick "memory" written down as it happened, has turned
into a veritable thesis for no apparent reason.
As I have said at least twice before it was over 30 YEARS ago and things
change. Modern alternators might drive the entire electrics of a car and
the battery might ONLY be needed now in order to start the car. Somehow, I
doubt that they are THAT efficient though!
With fancy computers installed in many, but by no means all cars nowadays,
I would be very chary of experimenting in similar fashion today and would
not recommend it at all. Thankfully, it is many years since I had major
problems with my cars, although I have occasionally had to jump start the
odd one.
I spent considerable time fixing and maintaining my own cars. Sadly, many
of my early cars were dare I say it, pretty rough :( as I just could not
afford any better. Consequently, I was forced the hard way, by several
breakdowns, etc. to learn a great deal about cars and how to repair them.
I became competent at repairing them and spent considerable time, under
the bonnet, the gearbox and just about everything else.
Circumstances demanded that I was forcd to learn how to change brake pads,
brake, shoes, brake linings, wheel hubs, clutches, gearboxes, engine
rings, (I even bought a compression tool and ended up doing it by hand)
and even engines. Quite a substantial number of them! I ground valves in,
(Exhaust valves rather than inlet valves are more usually the culprits)
removed and replaced heads after skimming, in one case as no comparative
exchange was possible, I was forced into changing it with the head of a
high compression engine with a consequence increase in performance. Ah the
good old days. You can stuff them Hi! I spent far too much time repairing
faulty cars and not enough time enjoying my life!
No matter, I did learn a great deal and rarely had to rely on another to
get me out of a fix. It is all down to life's experiences. We all learn
similar, or different things, as we face life. Sadly, much of it dies with
us which could benefit others. Such as dowsing. :)
I trust this answers all your querstions Dick. If not. Please be specific
and ask a question. Thank you for your time. My best regards, Jeff.
