<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>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).<br>

<div>I do think a coil mounted on an alternator would look
silly, but that's just me.<br>

<p><span>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.</span></p>
<p><span>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.</span></p>

<p class="MsoNormal">I’ve had an alternator in my BT7
for a while now.</p>
<p class="MsoNormal">So, when I was doing the job, I
looked at pictures of other people’s installations.
Nobody’s coil was mounted on the alternator as coils
were/are mounted on the generators.</p>
<p class="MsoNormal">I didn’t mount mine on the
alternator either.</p>
<p class="MsoNormal">Now, I’m wondering why everybody
found ingenious places to put the coils and nobody
ingeniously adapted their brackets to fit onto their
alternator.</p>
<p class="MsoNormal">Do alternators get too hot? Do they
give off some kind of magic death ray that fries coils
or what??</p>
<p class="MsoNormal">Any reasons not to do it??</p>
<p class="MsoNormal">Thanks,</p>
