DEAD in 3 DAYS?? Ford Parasitic Battery Drain ('12 Focus)

Owner of this 2012 Ford Focus wants to sell the vehicle, but he says that the BATTERY GOES DEAD after 3 days of sitting. He wants the PARASITIC BATTERY DRAIN issue DIAGNOSED and REPAIRED before selling the car. Let's see what isn't "falling asleep" on this Ford. There is one more variable: an AFTERMARKET Remote Start System. What will we find? And will any PARTS be required? TOPDON Phoenix Plus: https://www.amazon.com/dp/B091BQNR3S?...
