Reporting back on resolving the issue.

I tested voltage at the starter from battery. Then tested voltage from yellow small gauge wire with the slip connector when attempting to crank the car. Voltage at the wire was good.

Glen was right earlier in this thread. I found that the slip connector and wire crimped in the connector was extremely corroded. I clipped the old connector off and stripped some fresh wire for a new connector.

Fired right up after that. That connector is fairly exposed to salt / road elements — would highly recommend other folks with starter issues check this fitting if they’re having issues like mine.
