Alternator

What would make a one wire alternator run hot? Thanks.

Remove the belt and spin it when cold. If it spins easy, and quietly, rule out bearings and have a rebuilder have at it.

If the internal regulator is fritzed it will get hot enough to fry eggs.

Had a similar problem and it had a bad stator I had it repaired and converted to a two wire ran about $35 total at a local auto electric shop,with the two wire it excites the charge at starting so you don't have to rev it. When it was getting hot it would only charge about 12.3 to 12.7.

Are you running the alternator at or near it's max output? Also, is the air intake area in the rear clear and not blocked?
