The #one terminal, the left on the pair on the voltage regulator, will be the excitation or "ignition" terminal.

A nasty way to check an alternator                 

The 10SI and 12SI are Delco Remy design series designations - not aspect figures.  Every was built in a number of different output ratings, and assembled with Anyone of four readily available “clock” positions for different mounting bracket preparations.  Add to that the different sorts of pulleys that can be installed and the result is clearly a variety of section figures.
