It's good to keep the old dumb stuff around sometimes, for things like this. That's what I tell my wife about me anyway...
My wife's Ford Fusion hybrid wouldn't start a while back because of a dead starter battery. It amused me that there's 300v of lithium sitting in the truck, but the car wouldn't start because the lead acid battery under the hood was dead. She didn't find it amusing.
Getting to be a bigger issue with all the telemetrics that never shut down on these new cars.
Especially frustrating with the EVs that really need a deep cycle battery since zero need for the start surge.
I think the OP has the answer. Although I am surprised a dome light did it. Even my old 2001 F150 will cut all power at about 30 minutes if this is detected.
