my first susgestion is forget about the one wire alt, they can be tempramental, wont start charging till the engine rpm reaches around 1000 rpm when the engine is first started, and they have a habit of draining the battery over night, i would use a chevy 3 wire alt, only one wire more is needed to work, the exra wire needs to be hooked to a switched hot wire from the ignition, on when the key is on off when the key is off, and they are cheaper and can be bought at any parts store, if you dont know how to wire the 3 wire alt let me know and i will tell you how its done
