Well, you guys just shot my confidence full of holes. I thought my genset cranked off the chassis and that both terminal busses, that Richard mentions, were chassis.
So I just went out and shut off one and then the other battery mains, and the generator started when either one was on! Aarrghhh! And my 2 terminal busses show no AGS on either one, just several genset terminals at the top of TB2 (terminal buss 2); gen ground, gen start, gen run/stop, gen running, gen diagnostics.
But maybe such chaos contributed to why no one, not even BCS, could get my AGS set to work right, so I stopped trying to use it 13 years ago.
