remove negative battery terminal and connect in series an ammeter or even a bulb pref head light bulb , with all consumers turned off ( as it would be parked) the intensity of the bulb will tell you how much off a drain there is , you can then begin to remove fuses one at a time when the light goes out you will know which circuit has the drain and you can investigate further
keep it real

Put a multimeter (current setting) across the battery (-) terminal and the (-) lead (disconnect it first) and pull fuses one by one until the drain stops. That will tell you which circuit the drain is on

If pulling fuses doesn't locate the problem, it will most likely be the diode pack on the alternator. In this case, a new alternator is quicker and easier.

Maybe if you replied to one of your other many threads on the subject that you've started we'd know what you've already tried.

I'll link you to one that has the the info you need that you never replied back to.
