Too Much Alternator?
I left on the alternator from the 73 Lincoln when I put dropped the 460 into my 70 F250 that has a 360.
This last time when I ran the engine for a couple of minutes a wire started to smoke. I shut off the engine and it looks like a black wire that goes from the starter relay to the regulator.
Are regulators matched to certain alternator Amp ratings and could a mis-match cause this kind of burn out?
If I could find the right brackets, I would put the old alternator back on.

Too Much Alternator?
Rod, I waited for good technicol answers, but my gut reaction is a wire is attached wrong or it's the voltage regulator. Altenators are built to handle demand loads. The regulator should stop current flow as needed. When we start dealing with old pieces we can get faulty ones as well.

The wire went to the starter solenoid on the same side as the battery attaches.
When I took the tape off the wires I noticed the burnt one was labled "Fuse link", So i guess it did its job!

Could be the regulator then.
I replaced the fuse link wire, put the old alternator on and bought a new regulator!
There was a small wisp of smoke from around the new regulator when I first turned they key on, but I never saw it again once it was running.
Thanks for the help
