Hi Josef,<br>
<br>
Well...., increase the diameter of the wires from/ to the
alternator and the H4 bulbs if fitted. The old head light bulbs
are to dim for modern traffic conditions and you will also need an
electric cooling fan to keep you out of trouble.<br>
In my view it is advisable and permissible to make small
adaptions to an old vehicle if you want to use and enjoy it in
modern traffic. You cannot travel the same way any more as in the
olde days.<br>
<br>
Cheers,<br>

<p><span>There is never a need for additional power, except your
regulator is not well tuned. Better to set the regulator
right. The wiring in an Austin-Healey is not prepared to take
the up to more than double output current of an alternator.
The cables can get hot, can melt and get brittle inside the
wiring loom. Same can happen when switched from ordinary
headlights to H4 halogen headlights. The feeding cables are
too thin for the current flowing through.</span></p>

<div class="moz-cite-prefix">The main reason for changing to an
alternator is that it produces a high(ish) charging current
starting at low speeds, usually around 35A (e.g. Lucas 100).
Therefore the total output is higher. Especially if you drive
the car with headlights on all the time and/or have an
electric radiator fan, high power radio etc. you are better of
with an alternator. It also is easier to maintain thus more
reliable than a generator plus regulator.<br>
Most generators produce 20-25A max. at high speed but will
barely cope as they do not charge much if at all at low
speeds. <br>

<div>Simon,</div>

<div>My knowledge of electronics is limited, but I do know
the basics. I can't think of any reason you couldn't
fasten a coil to an alternator, except maybe their shape
isn't as convenient for such use. Alternators are
generators--my 2008 Mustang's shop manual even calls them
that--the only difference is how the unit converts
alternating current to direct current, which is needed for
charging the battery and for most other electrical needs
in a car. Generators physically 'commute'--the more
contemporary term is 'rectify'--the AC with brushes and
the segmented commutator--hence the name--while
alternators commute the AC with diodes. If anything,
alternators produce less electromagnetic
interference--EFI--than generators since there is less
chance of creating a spark. Alternators are more
efficient--correct me if I'm wrong here--because without
brushes they can be spun faster for a given engine speed
(note alternator pulleys are usually smaller than
generator pulleys).</div>
<div> </div>
<div>I do think a coil mounted on an alternator would look
silly, but that's just me.</div>

<p class="MsoNormal">Thank you for this. As ever, all
advice sought is welcome. However....per my comment
to your answer to my (previous) BJ8 questions, it
would be really helpful if you applied your huge

sure that your knowledge is encyclopaedic, but maybe,
when you’re asked a simple question by a simple

<p>People who swap a generator for an alternator like to
modify in any way. Anybody who knows more about
electrics know there is no need for an alternator at
all on Healeys. its only to adjust the rehulator to
work as it should. But that´s to difficult for most I
suspect.</p>
<p>those selling these alternators are quite happy to
sell them as people like to modify and they also sell
you one of these performance coils and they need to be
kept cool and best is to put the coil in the boot to
keep it cool. Haven´t seen that so far but can´t await
to see it.</p>
