Old-Biscuit, Golden_HVAC, Ivylog, and j-d, thanks! Appreciate all of you taking the time to reply with all your helpful tips.
Got up this morning and pulled the 5uf/50uf start cap and measured 4.6uf on the 5uf FAN terminal, and 3.9uf on the 50uf HERM terminal. Ok, the compressor side of the cap is bad.

Installed the new cap. Switched the fan on high and turned the thermostat to max cool. Heard a click, followed by that faint hum of the compressor. Within 15 seconds I was getting a nice blast of cold air. Works great!
Inrush current was 62.1a on home, commercial power (LRA is 63a). Continuous current was 12.6a (spec'd at 14a). All looks good.
Thanks again!
