A few weeks ago someone pointed out the Iraggi alternators on Ebay's
stores. I got one (200 amp version) for my SVX powered westy.

Included with it was a t-shirt (!) and a couple of pages of notes,
with comments about making sure to upgrade (add addtional) wiring to
the battery and grounds. And also that they explicityly do NOT
recommend the use of battery isolators or relays.

After I've done some wiring cable runs I will get this installed in
my Westy.
