Yellow/black stripe wire on the back of your Gen. should be (A) armature
White wire on top or side is (F) field
Black/red stripe on top or side is the ground (G)
You should have some letters stamped on the Gen. housing to help and your Regulator should have some markings just make sure the wires where never swapped by mistake.
You will also have to polarize your Generator
Just make a jumper wire and touch the Battery terminal and Armature terminal momentarily (you will make a spark, np) Hope that helps
