I have a NOS KEM generator cut-out switch. Model MCO-120. Any info on what this may be used on? Positive or negative system? I'm assuming it is 6 volt. Any info would be appreciated.

Unless you're running an antique 3 brush generator without current and voltage regulation, a separate cutout relay isn't needed. A 3-unit regulator has a cutout built into it. It's the component under the cover behind the BAT wire connector. Lots of old tractors used 3 brush systems and a cutout relay. Ditto for 1930s cars and trucks.
