When you ground the field wire on the starter/gen it should go “full out” and that is generally somewhere around 17v or so

If this isn’t happening then double check all your connections and make sure the engine/cradle/starter gen has a good ground connection. These are notorious for bad engine grounds. You should have less than about 3 ohms from the engine (anything metal) to the negative battery terminal.

If all is good and it still doesn’t increase voltage when you ground the field wire it’s a bad starter/gen. What kind did you get? Oem or aftermarket?
