kurt.......you ask......."what is the cutout?".....NO it is NOT the ignition switch. The original 6-volt 2N had a 2-terminal roundcan "cutout" on the side of the steering column underneath the battery that disconnected the battery from the 1-terminal 6-volt genny. ...otherwize... yer battery would discharge thru the coils of the genny. Henceforth the name "cutout". Simple, eh?
Would it surprize you to learn that yer 12V alternator has an internal solid state "cutout" to disconnect the alternator from the battery so it don't discharge. Isn't that amazing??? ........respectfully, Dell, a 12V advocate for the right reasons who knows 8-ways to convert and they all work the first time
