Clifford alarm? (my old concpt 50 would drain montego in bout 5 days)
Has it always done this or just started?
Have you added anything electrical to your car?
Check your fuses as sometimes a blown one can make wigglys do funny things.

Do a current drain check and see if you (or an auto electrician) can trace it that way

Battery leakage current

It's along time since I did one, but you need a meter ( I used to have a gunsons multi meter)
You have to disconnect the battery +terminal and connect the red (+) lead from the meter to the battery+ terminal amd the black lead to the battery lead you disconnected. It will then show you the leakage current.
On a 40AH battery .5A is 3 days
On a 60AH battery .5A is 5 days
