Does that sound correct to you?

Not sure how you are trying to do that. You're trying to connect a low voltage indicating circuit (let's say 3 VDC) to a terminal with 12+ VDC on it?
Need a schematic to see how that would work. The only way I see accomplishing this without auxiliary contacts on the latching relay is a logic/compare circuit that would sense the voltage on both sides of the latching relay and drive an indicating lamp.
Basically, if the voltage to ground on both sides of the latching relay is less than .1 VDC difference and battery side or converter side is greater than some minimum voltage (say 5 VDC) then light the indicating light.
