Has anyone any links or a copy of a basic charging circuit diagram, its 3 wire altenator etc.

have a look here:

http://www.polevolt.co.uk/electrical.htm

well 3 wire alternator is meaningless as there are variants.

but the very basic wiring is shown below. 2 wires really, one for the charge lamp and other for the output.

the third wire is for earth (to complete the cricuit) and done via alternator body.
