Oh those were the days! The wire coming from the coil to the distributer seemed to always be "porous" causing the capacitor charge to leak out into whatever unsuspecting human was leaning over and getting too close to it. I still have a dent in the top of my head when I got zapped by that coil wire and my head shot up and impacted the stupid hood hold down latch pin that looked like a bullet pointing down! Till this day I have a healthy respect for any capacitor.

Dometic says to use a VOM set to 500v or higher range. Black to one wire, then touch red lead to other wires one at a time. Don't need a fall from 13' up on an RV roof!

As a professional HVAC tech for 25 years... I verify no power to the unit, phase to phase and phase to ground. Then short the caps using pliers or a screwdriver. Replace them one wire at a time. Do not save them as spares, buy a new set of spares if you are worried about it. Capacitors are cheap, compressors and fan motors are not.
