[TR] Nippondenso mini alternator (coffee can, racing, etc alt)

[Frank Fisher]

 Some of
our Triumph brethren on the other side of the pond are splitting the
calipers to put spacers between in order to run vented rotors.
 
what a neat
idea. do you happen to know what the source of the rotors are? Toyota again?
 
i have never had a problem splitting the rotors. it aint rocket science. and i
like the idea of vented rotors.

Following up on the thread below - the Suzuki Swift alternator.  A
number
of racing catalogs list a small light weight alt for big $$.  I bought
an
e-bay  one (didn't know it was Chinese until I received it).  Earlier this
Summer I happened upon the Sideways Forums (
http://sideways-technologies.co.uk/forums/index.php/forum/1-technical-discuss
ion-boards/
),found the Small Triumph archived folder and started reading the
posts and
found several articles referring to the mini Denso alt and
recognised the
alt as looking like the one I bought off e-Bay.  I suspect that
this is the
small Nippondenso alternator.

>From my reading, the smallest of
the alt came with Japanese mini cars at
about 40 amp.  Same alt, but only 25
amp, found on Kubota tractors.  Some
links:

http://westfield-world.com/daihatsu_alternator.html (has wiring diagram)

I
was at a pick & pull type of salvage yard and found an 85 Honda Civic
with
what I thought was the mini alt.  Once I had it removed, it was the
same
pattern but a size bigger.

BTW, every so often the discussion comes up about
dismantling frt brake
calipers (and how the caliper bolts are sacred - don't
undo them).  Some of
our Triumph brethren on the other side of the pond are
splitting the
calipers to put spacers between in order to run vented rotors.

Thanks,
Jerry, I'll pass that along.

Chris "Mad" Marx told me
that his came from an 89 Suzuki Swift.
Unfortunately my FLAPS didn't have that
one in stock, and I don't know the
application for the unit they sold me.  It
is not a single wire design,
there are 3 control tabs as well as the main
output.  I haven't researched
yet what they are, but I'm guessing that one is
for the dash light, one is
battery sense (which you could just wire to the
output if you want, I will
wire it to the starter solenoid), and the third
needs to get power from the
ignition circuit.  That seems to be what most of
the Japanese alternators
use.
