Yeah, I know, there's a group by that name devoted to abuse. Nevertheless:
Wingnut (who should have known better) hooked up a new compressor-unit blower motor to a non-split capacitor instead of the stand-alone variety capacitor.
Fried the blower motor.
My quest is for the basic reason(s) on what went wrong, that is, why would connecting the capacitor leads to a non-split capacitor (that's where the previous motor was connected) vary from a stand-alone capacitor on a PSC blower motor.
Thanks for adding to my store of probably never-needed-again knowledge.
