Luke, Regardless if the tractor has a simple 2 wire cutout relay or a 3 or 4 wire Voltage Regulator, the cutout relay or the cutout relay portion of a VR should have been normally OPEN whereby there shouldnt have been any electrical path to the Generator from the battery allowing it to draw current. Common problems on a bad cutout relay or VR could be stuck/burned/carboned contacts which would allow a curent path. They are designed to be normally open unless and until the Gens output voltage exceeds that of the battery then they close but open otherwise so the battery dont discharge through the generator when shes turned off.

Other considerations may be the battery polarity were reversed?????? Did you connect the new battery at Positive or Negative ground cuz many tractors were originally Positive grounded but some got changed over the years?? Some cutout relays are bi polar and work at either polarity simply by reversing their wires. Also, was/is the tractor 6 or 12 volts?? do you know or know if it got converted???

Correct voltage n polarity issues need to be known and dealt with accordingly, but Im more of a John Deere man and know their original voltages n polarity better then an IHC, sorry. Bob has good data n diagrams etc on all the the IHC stuff.
