Thanks. I was well on the way to planning the mod and then I did a reset. Top level requirement seem to be to alert as soon as the alternator stops supporting the full system load. When that happens the battery will start to discharge but its voltage won't immediately drop to alert level.

What I did, perhaps interim and perhaps final, is to change the alerting levels for the existing battery current shunt. I have set it to produce a CAS alert any time the current is zero or negative (battery not charging). This means it will always alert before engine start but should never be active in flight unless there is an alternator system failure.

I saved the config file and made screen shots before making the change so it's easy to go back if I don't like it.
