It's something in your batteries/wiring- to confirm start engines (one side and battery at a time) and then turn battery switch off. Carb 502 Mag should keep running with batts off, if you get the same reaction when hitting trim switch, horn, etc I think you rule everything else out. Idle should be fine.

Alternator should run that engine without battery but any switch being activated affects voltage going to ignition and hiccups. Not sure if running electric fuel pumps.

I shut my batteries off when i'm done for the day. Nothing works with them off. The dash is dead. How could the engine still run?

Pretty sure that is a big no,no.

Agree, disconnect the battery from a running motor and your going to need another alternator
