Assuming you have the factory amp meter, you have by passed the circuitry that sends the signal to the amp meter. The factory amp meter gets its signal as a result of the resistance in the feed
wire. With the way you have wired your altenator directly to the battery the current from the altenator does not flow through the original wiring, hence you get a discharge reading because power is flowing from your battery to your dash/ignition, etc...
With the factory hookup, the flow of power went past both amp meter pickups, now you have eliminated that feed to the altenator.
I would refeed the alternator to the original power wire, (red #10)
that goes across the radiator support and into the bulkhead fitting. That is if you have the factory setup.
