[T3] Alternator Tip
Hi all... I just came across a members page on this .org that tells the story
of the alternator conversion much better than I can. Mine is very much like
his in the way it sits on the engine... HINT.. HE HAS PICTURES.

The difference is, I cut all of the brackets off of the alternator, where he
left his on. The RX7 alternator was a 55 amp up until 1984... then went to
70amp. It is a Mitsubishi as I have said before. I DO NOT KNOW THE STOCK
PARTS NUMBERS.. but a auto store could tell you.. even Pep Boys could. Junk
yards seem to have lots of RX7s in them.. Wankle Power Dies Young I
Guess...lol. On this alternator you just make a new strap that goes over the
alternator like the generator.. just a bit longer in length of the metal
strip than the stock one. The main power wire comes off the back of this one,
unlike the one he used. You WILL NOT have to put Hose Insulation on this one.
And best of all, The stock pulley fits right on.. so it can be adjusted like
a stock generator. The cooling fan and the stock Mitsubishi pulley must be
removed so that the VW pulley can go on. There seems to be enough air coming
up from the fan housing through the generator cooling hole to keep this thing
cool. It was just 102 here in LA and it worked like a champ. No sheet metal
was harmed in the making of this movie...err.. alternator modification!
Follow his wiring instructions for the modification of by-passing the Voltage
Regulator. This Mitsubishi model has it built in like the Type 1 alternator
does.
Hope this helps ... Pat
