This is what I do. Place gen in a vise, ground the vise, apply 24 volts to the main battery terminal on the gen, jump the field wire to the main battery terminal on the gen. DO this first and try to spin the gen by hand. It should be tough. Next step, attach a high speed drill to the bolt on the front of the gen where the pulley goes, spin the heck out of it and use a volt meter to check for correct voltage when the field is jumped. There is also a voltage adjustment screw inside the gen.
