Try your battery cable spark test by removing one alternator cable at a time. First remove the two wire plug at the alternator, then check if the bat cable sparks are gone. If the alternator is the type that has the side plug with red wires attached in Bob's picture, make sure that only the one marked #1 on the case, has power when the switch is on. With age and weather, those alternator plugs get rotten and allow the plug terminals to pull out of the plastic, so it is easy to get them on the wrong terminal. If those wires are reversed, it will drain the battery. Any auto parts store has new replacement plug kits for around $2. Replacing it protects your tractor from battery drain or electrical shorts /fires from the alt terminals touching the alt case. If the alternator has the rear plug as shown in Bob's lower picture, a battery drain can be a bad external regulator under the steering column base, remove the cover plate right at your feet level.(remove the 4 wire plug from the regulator and see if the bat cable sparks are gone), if so , regulator has stick field relay points.
