To test Capacitors with a Meter that shows "Capacitance" "MicroFarads" or "uF"...
Shut Power OFF.
Short across Capacitor(s) with an insulated tool like plastic handle screwdriver.
Disconnect Capacitor from Circuit
Apply Meter Leads
Should read out within about 10-pct of the rating on the capacitor label
Pix look better! I can now see that you have
Combination RUN Capacitor supporting Fan and Compressor with separate sections
A Start Assist Capacitor
A Start Capacitor Relay
You can replace your combination capacitor with two separate ones with the right rating. You need a Jumper to connect one terminal of each to one terminal of the other, forming a "Common"
You capacitors may be labeled 370-volts-AC and new ones are usually labeled 440-volts-AC. That's fine.
