Conflicting logic!

Funny, I was actually had a passing thought of a similar circuit to defeat (block out) a starter switch IF the engine is running.

Keeping it old tech, I was thinking of using a relay to sense that the alternator was spinning (ie engine running). Relay is energized when alternator output is devolped (same as old mechanical regulator switch over)
