Now I'm just flailing and sharing my confusion. I came back to the project a few hours later to find the start battery voltage down to 12.5V. There was another .4A of load on it, seeming to vary a bit. So I just pulled all the fuses in that part of the front load center: CB radio, cell phone, audio amp - all unused anyhow. That seems to have cleaned up the phantoms.
Then I checked the back of the AmpLStart to be sure I had the jumper installed correctly for the lithium house bank - yes. At the time when I reconnected everything, the inverter was in quiet mode at 13.6V. And the AmpLStart went into Maintain mode, putting out only about 12.6V at 4.5A to the start battery. Shortly thereafter, the inverter reverted to Constant Voltage at 14.4, and the AmpLStart indicated a solid yellow charging state. BUT there was no current going to the start battery. So I'm starting to think I have a bad AmpLStart. Really??
