I was looking out at my left wing tip yesterday afternoon and saw steam, so I took a picture!  With the recent surprise eruption the FAA seems to have changed the TFR size.  I can now fly closer! ???  It was not good lighting for photos, but below the plume is the original crater.  Behind the plume the more recent one, some 800' high now! Also evident is the pacific NW's drastic lack of snowpack so far this year, only 25-30% of normal.

And they're both 30 bucks on a wreck yard shelf, can be capacity tested free and be rebuilt for another $30 or $40 if they need it.
I've concluded that I've no need for anything but N-D alternators, and no need to buy them at a store. Aside from Paul, I don't recall ever having known one to fail. ... Jim S.

Hi, Steve... unfortunately, I did not weigh the Geo alternator, but it is definately smaller and lighter (probably by about 1/3 lighter).  After having my stock Mazda alternator fail because the plastic inside broke and the screw got jammed into the field windings, then having it rebuilt by the local alternator rebuilder who said the insides were cheap and poorly constructed, I decided to give it another try. Two weeks later, the alternator started overcharging.  That was it's last chance.  Two strikes and you're out.
   The Geo alternator looks identical, even the casting has the same number of vent holes, same mounting tabs, same connector plug, etc.  A carbon copy except for it's size. I wouldn't be surprised that they are both from the same manufacturer.  Paul Conner

Paul,

Very nice.  I'd heard before that t was [possible to
mount the Geo alternator on the 13B, but I hadn't ever
obtained one. I also "feel" that the Mazda is more
reliable, but that is just based on knowing how GM
cuts corner, especially on low end cars.

I'm curious if you weighed the stock alternator, and
the Geo, to see how much weight difference there is.
I'd be prone to change just for the weight loss.  55
amps would be more than enough.  I've never seen more
than about 40 amps after start, and that is just for a
few seconds.  Normal running current seems to be in
the 13 amp range, with just engine and GPS/Comm.
