Jim, I'm not sure what gen type a 640 has, but if it is a type "A", where the regulator controls by grounding the field, then that is same as 8N Fords and if he applied battery power to field, then he probably did weld field points closed.
If he read on Ford board that you polarize by applying battery power to the Field, then he was likely reading about a NAA, Jubilee, or later tractor where the Gen is type "B" and control is by reg supplying power (not gnd) to the field.
OK, I just figured out that you apparently have a Ford 640, not a IH640, so you probably polarized correctly as it is type B.
