I didn't get the new one installed yet. I'd mentioned a different cap
I had but it only served to reassure me that my multimeter's
capacitance test function still worked, that other cap was too low a
value to use.
Since it's Labor day today, I'm waiting till tomorrow to get the cap
locally.

I highly suggest that you make a call to your favorite HVAC company, as it
is painfully obvious that you *don't* have basic electrical skills!

Thanks for trolling by. My favored HVAC company stuck me with a bill
in excess of $200 for a $17 capacitor that takes 5-10 minutes to
install and then failed 2 years later. If you'd call them again, go
right ahead.

Do you have any clue why a capacitor and service call cost "in excess
of 200.00"? I am sure you don't or you would not keep making assinine
statements. We are running a business, not a charity asshole. Now go
the fuck away.

What a maroon;
Don't you know any other adverbs or nouns besides four letters? You're such
a jerk you're pathetic.
