Yeah, I'm betting that the cap is as old as the motor. I'll take your
advice and replace it. I don't understand how the current can be
different if there are only two wires feeding the motor. What am I
missing?

If the capacitor's value is wrong, it doesn't provide the proper phase shift. That causes the motor to require more power to do the same work.
