Can't see the lightbulb idea working very well. It certainly wouldn't

it would give 240v any time the train wasn't sat on the track!

Today's conditions do largely stop the weeding out of the gene pool, though I doubt anyone involved would see that as a positive thing. All kids do stupid things, it doesn't make everyone stupid adults though.

Not that I think turning the engine around had any effect on the

I'm trying to remember my many Minis owned a long time ago, but I'd
guess if you could have located the battery at the front, it would
have been where the Minor one is - just below the windscreen. And I
don't think there was room given the carb and filter are there.

See the picture at the link I posted. It was under the bonnet, on the
opposite side to the fan.

Ah - just looked at it. However it does beg the question if the engine
end plate and clutch cover etc with the new transfer gears had the same
sort of space available. I'd have thought boot space on such a small
cheap car more important than weight distribution for handling.

There was only one extra gear, in a vertical plane, so I don't think it
made a lot of difference. The battery was still under the bonnet after
the engine reversal - I just don't have a picture of it. See my earlier
quote from one of the decision makers - he was really quite worried about
the rear wheel lockup problem.

would have been a recipe for disaster.


Yes remember this now the mini vans i was rather fond of used the have
the exhaust descend down the back of the block at the rear. There was a
simple stabiliser bar that had a couple of rubber bushes therein that
used to deteriorate so that should you drop the clutch or be less so
with it the engine would jerk fore and aft and snap the clamp joint
and emit exhaust fumes and be rather loud about it very poor bit of

Dont think regulation needed to be too accurate ,as you will know at that
stage the voltage and type of current
varied widely around the country.
The resistance box was supplied without a lamp as the intention was you
installed one that was for the voltage in your area, the lamps should have
been carbon. filament.

Hornby were not alone, this article describes the very similar system by
Marklin at the same period.

There was a specific decision to move it from the engine compartment, as
discussed here (by a close friend of Issigonis):

"...he (Griffin) made some calculations based on facts about wheelbase,
weight distribution and centre of gravity which proved that really hard
braking could result in locking teh rear wheels and complete loss of
control. This being an incontrovertible argument it led ... to the
transfer of the battery from the engine compartment to the rear luggage
locker, so as to transfer some weight from the front to the rear, and to
the introduction of the rear-brake limiting pressure valve."

So clearly the battery *was* originally in the front. This is also shown
by an early photograph of the engine compartment, which shows the battery
(note that this particular version has the engine oriented the other way
round - later changed due to carburettor icing).

Only ever experienced carb icing on one journey long ago on the middle lane of
the M1 on a very humid July day (not on a Mini) It scared the crap out of me.
Gradual loss of power over half a minute and then zero power and a lucky coast
with the clutch depressed to the hard shoulder.

No amount of cranking would make it start. 10 mins later the problem went away
only for it to happen again a few miles up the road when the ice in the carb was
obvious. The cause? Failure of the piping from the hotbox on the manifold
to the air filter inlet tract / mixer flapper so only air at ambient got to the
carb rather than something a little bit warmer. Good for more power but only
with very dry air.

irrelevant perhaps but:

We had a Morris 1000 in the 1960s. I remember that the dynamo was not quite able to charge the battery if all the electrical loads were on (heater fan, lights, and windscreen wipers).

We had a Morris 1000 in the 1960s. I remember that the dynamo was not
quite able to charge the battery if all the electrical loads were on
(heater fan, lights, and windscreen wipers).

The dynamo should be able to cope, if in good condition.

Regarding mine, the problem has disappeared, but that is probably only
temporary. Several short and longer journeys, battery connected at all
times, and battery always fully charged.

The battery is probably on the way out, as said by Huge and others, and
I'll get one when this one finally dies. In the meantime, the starting
handle works, if required :-)

It's a close call if you add it all up. There's the ignition and
occasional brake lights and indicators remember. I reckon you could
touch 22A at times.

Even in good nick dynamos of that ear could only just keep up with the
loads..my car fixing period started in the very late 1960s and by then
everyone was retrofitting alternators.


It was the availability of rugged silicon diodes and transistors that
made alternators viable, and signalled the end of the 'control box'

I don't actually understand why alternators were capable of supplying
more current though.

But IIRC they ususally ran a bit faster on smaller puleys so they worked
better at e.g. idle

IIRC it was because they could rotate much faster overall. At low engine
revs the dynamo wasn't putting out that much power and it IIRC again
couldn't stand being rotated too fast whereas the simpler mechanical
alternator could which was capable of giving a higher output with low
engine revs such as waiting in traffic..

But IIRC they ususally ran a bit faster on smaller puleys so they worked
better at e.g. idle

Yes!

Because they were designed to do so.

Larger dynamos were also fitted to larger cars, etc.

Alternators spun more freely than dynamos.

Because an alternator doesn't have a high current commutator/brushes, it
can be spun much faster. Giving a higher output at lower engine speeds,
with suitable drive gearing. But then petrol engines also have a wider rev
range than once was common.

If you really wanted to use a dynamo these days you could add a fluid
drive to limit the maximum RPM. If you cared that much.

But basically all common alternators had a higher maximum output than the
dynamos that proceeded them. Probably because increased demand from
vehicle electrics arrived at about the same time.

Cant see how that is relevant given that
they are locked to the engine speed.

I'm surprised that some pedant hasn't pointed out that all alternators
/are/ dynamos - which can be AC or DC - it's just a motor trade
convention that the word "dynamo" was kept for the original DC
generators when alternators came in.

Possibly because the pedants know that a dynamo usually has a commutator and
directly produces something resembling DC, an alternator usually has slip rings
and produces AC that has to be rectified.

The classic bike brigade often fit LED indicators etc in a bid to save as much lecky as possible for the main light.

I wonder if its worth doing something similar with a moggy (me, Id fit an alternator)?

They are both generators - but the definition of a dynamo is a generator
which produces DC by use of a commutator.

As per definition in the wiki article:

Yet the 'dynamo' on my old bike produced AC.

Apparently I should have been calling it a 'magneto'.

Never hear then referring to the Alternators in a power station as
Dynamo's!..
