by burn I take it you mean waaay overheated:
bad bearing
bad regulator
high demand on insufficient wire diameter

Burn up from overcharging because of a bad regulator. Should have blown some lights and 12 volt accessories or they were on the verge of being blown.

Bad battery (dead or shorted cell) - forces constant full output from the alternator, which will fry it. Alternators aren't designed to charge dead batteries - only to maintain them.

well........
IMO that leaves regulator or excessive demand on inadequate wire.
Has electrical equipment been added to the car - e.g. electric pump, fan, megawattstereo, 100wattalternator - without upgrade to the harness?

Please discribe "burn up". Is the unit getting too hot, making noise, smell bad or just stopped working?

my dad and I was in the car going down the road and could smell a burning smell. like something electrical. pull over open the hood and the alternator was very hot to the tuch and the wiring that you can see throught the back was black. and when we shut the engine off you could see smoke coming off the alternator.

Keith,
Have you checked the fusible links?
