This is a way to test it; but you also need to see how the BIRD or BCC, which ever system you have is wired. On ours the power that feeds the BIRD and the Aux or emergency start switch was on the cranking side of the isolation, Trombetta, relay. Thus when our cranking battery was dead, 4.5 volts, we were unable to pick up, energize the isolation relay which ties the house and cranking batteries together.
I posted a pic in another thread. I'll try to find it.
