Question about the alternator and the alternator regulator

[Talns100]

Hey there, I am using the N1505 I alternator with the N3135 regulator dual voltage configuration and I want to know what each connection to the regulator does (the two harnesses, AC and IGN)
Thanks in advance

The IGN excites the alternator, the AC tap tells the EESS box the engine is running, the 14V tap goes to the connection between the batteries and the large insulated post on the alt goes to the 24V battery connection.

What about the two harnesses?

That is shown in the attachment I posted

Does the alternator need regulator to work? Will it charge if no, why?

Yes it needs a regulator, the regulator excites the field that causes the alt to produce energy.
