From personal experience the only thing you really need to know about that amp meter is if you run a ground wire to the battery negative terminal that wire must pass through the amp meter as well. Lets say you don’t do that, after a while (not immediately) you will get a “battery saver active” warning on your DIC. Don’t ask how I know that.

Basically GM uses that amp meter to monitor the state of charge in the battery and adjusts alternator voltage in an attempt to keep the needs of the car meet while trying to maximize the life of the battery. If you bypass the amp meter the whole program eventually goes out of whack.

Good luck beefing up your system man
