Default Ammeter Shows Discharge - Alternator is Good. Now What?

67 Catalina. When I start the engine, the ammeter shows normal, just slightly above the mid-line. Then the needle moves slowly to total discharge after about 20 seconds. Stays at total discharge until I turn the car off again.

Checked the battery voltage motor off - 13.2v. Start car, voltage goes to 14.2v which tells me that the alternator IS putting out the voltage it should.

Got any clues?
