Need help with wiring for the build, recommendations for wiring or maybe a different alternator choice.

I am having issues with my alternator not working. I have a 3g alternator with a 4 gauge wire running to the starter solenoid and the two black and orange wires capped off. The battery is a brand new optima and the alternator is brand new, but when I read voltage at the battery it is always reading under 12 volts even when the rpm is up. I run after market guages and read somewhere that the factory guage battery light had to be connected for the alternator to work. Is this true?
From the pics of the alternator appears to be a 2g from a fox but he still has the external regulator.
