Hello, I made some checks.
My battery light stays on even after 2000rpm.
12.50v not exceed the voltage output.

cons but when I disconnected after contact I have 12v to the alternator excitation, and when I shall have only 1.2v.
when I direct bridge battery terminal ext smokes and still does not charge

Your explanation is not very clear. It's the alternator that smokes? If so, is it a fault isolation and must be replaced. Otherwise can you be a little more explicit?

If you do than 1.2 V on the excitation is normal since the exitaton through the charging of the dashboard so you have 12 V unplugged
Do not test the connection terminals who have never been connected to + you may destroy the regulator or the alternator

first check the condition of coal, by removing the regulator if available easily, if not remove the alternator to remove the regulator,
Disconnect the battery before starting with the terminal -
