Dear overtorqued and flatracker,
In the interim, since my first e-mail inquiry, I have paid $200 for a small alternator manufactured by Nippon Denso. Like my new Jabsco water pump, it is not original Yanmar equipment, so I am having to jury rig it into place. Once I get it mounted, it hope it works as well as the water pump. Anyway, thanks for your replies. Happy sailing!
