hello and welcome!
You should have battery voltage on the wt/db wire at the alternator. This Circuit supply's power to the Transmission relay also. Check fuse #1 20 amp, in the power distribution center for a open.
The Wt/db wire is the power supply for the alternator regulator.
The pdc sends battery voltage to the pcm and alternators internal regulator. Are you checking continuity with a ohm meter? You can still have high resistance in a wire but it will ohm test good. The best way to check a power circuit is with a test light. Using a test light puts a load on the wire and will not light up bright if high resistance is in the circuit. Using a test light does it light up when you test power on the fuse #1. Fuse #1 should always have battery voltage and is not controlled by the pcm.
