It only took about 1/2 hour to figure out how to do it, then another 1/2 hour to do it. But I recall seeing a written procedure for converting it since then. Most likely on the AeroElectric site. Todd 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. ------=_NextPart_000_00A5_01C526E9.169B0220 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable
