You can deterimine ground polarity like this: Install and connect a battery with the positive post on the grounded cable. Now while observing the ammeter turn on either the lights or the ignition (don't start the engine!). If the ammeter indicates discharge, the tractor is wired positive ground. Conversely if the ammeter indicates charge it is wired negative ground - reverse the battery cables.

Note - this test won't work if the tractor has magneto ignition and no lights!

Once the battery is connected correctly, good idea to polarize the generator before starting up the first time (momentarily jumper across the BAT and GEN terminals at the regulator).
