If a Cutout Relay (Bat wire to ammeter then battery, GEN wire to gennys ARM post) is wired correct and working, its an open circuit UNTIL the gennys voltage exceeds that of the battery at which time it latches shut/closed so the gennys output can get to and charge the battery. However when the tractor is shut down (or low idle) that relay opens so the battery dont reverse discharge through the genny to ground......
The Genny PLUS the CO need a good ground to work. Likewise the Low High Charge light switch needs a good ground because thats where the gennys FLD post goes to get its ground.
What you describe sounds backwards but maybe Im just not reading it correct. To be safe I recommend to POLARIZE a genny prior to start up. If the ammeter is wired correct to match the tractors polarity, with the tractor not running if you turn on lights or ignition it should swing to - discharge but then when running at fast RPM if the genny is good it will swing over to + charge. Yours do that?????? Most 6 volt tractors w0ere originall Pos ground you know
