Running an alternator open circuit is usually not a good idea due to high voltages. . The alternator needs to be bench tested at a shop where voltage can be monitored as the alternator is tested up to full load .
The alternator may also have been damaged when the tractor was jump started from dead. The alternator reads the dead battery as a very low impedance . The alternator goes to max charge for an extended period of time , overheats and fails .
Just because an alternator maybe “rated” for example 55amps . That 55 amps is an intermittent max for 5 minutes and then the load should not be more than 2/3 to 3/4 of the max nameplate rating.
The battery was probably ok until the phantom current drain has ran it dead flat . This will damage any battery and repeat draining to dead will ruin batteries for certain .
Need to Solve the problem first as treating the symptoms will not be satisfactory.
