Not really a "car" question this, but I have an 8 horse Honda engine doing nothing and I live out in the sticks with a poor electricity supply. I thought I'd build myself a generator by having the Honda engine driving a big car alternator, charging a car battery, and connecting the lot to a 2kW inverter. I've just become the proud owner of a 180 Amp alternator off a Passat, (2005-2010) but don't know what all the connections are. There's a great big stud on the back, which is obviously the heavy wire to the battery, and there's a small 2-pin connector socket that accepts an oval plug which would be on the engine loom of the car. Any thoughts as to how I could find out what to conenct to which pin? (and, indeed, where I might snaffle the matching male connector plug)! Would the alternator body need to be earthed to the battery negative?
The alternator is a Valeo 021 903 026L
