Simple swap of the primary coil wires and it rotates the other way.... and works !!
Just got the soild state regulator to fit, slip in an in-line fuse, job done.
Just need to get over my ocd that the dynamo goes in the oposite direction to the arrow on the casing !! ...that's tough that one...

Thanks for your help, I'll get some garage time over the weekend and get it sorted. I found the below link on the WD forum which I think explains nicely the difference between the two; http://pub37.bravenet.com/forum/static/show.php?usernum=3155626639&frmid=16&msgid=1399299&cmd=show Good...
