First- - - - -disconnect a battery cable! Never do anything under the cover of a regulator with the battery connected unless you're making an adjustment that requires the engine to be running.
Next- - - -use a piece of clean card stock like a strip cut from an index card, or maybe a business card, to burnish the contact points. Two of the point sets will be spring loaded closed, the current and voltage regulators. The third set, the cutout relay, will be "normally open" and will only close when the generator armature voltage exceeds the battery terminal voltage. NEVER, EVER, USE A FILE OR SANDPAPER ON REGULATOR POINTS! They open and close with a slight wiping action, and even microscopic scratches will make them stick.
BTW, the voltage regulator setting AGAINST A FULLY CHARGED BATTERY should be around 14.5-14.7 volts. Do not attempt to adjust voltage unless you are sure the battery is fully charged.
