Hi goodman888,

I'm not familiar with your car but I'm pretty sure you probably tested the battery with the hood open and the doors open so the car alarm was off, thus that circuit would not draw current.

You need to connect your ohmmeter probably with the help of some extension wire between the battery and the ground, set to read current (ma) while being able to have the car in it's normal parking position. That means hood down, roof up, doors all closed etc. Then you read the current. Then you activate the alarm (I assume it's a beeper) and read current again. The difference in current would be alarm related. I bet it will be high enough to drain the battery in 4 days.

Good luck

the 2nd time (and only the 2nd time) the battery was nearly dead, the alarm was screaming and even I removed the main battery, the alarm was still screaming and I could do nothing but waited until its back-up battery died too

Hi goodman888

Great looking car!

You've received some sound advice from all of the guys here, but don't be misled by your statement above. Many (most) car alarms IMHO would sound if the main battery runs down low. So that may just be a red herring.
Alos you haven't mentioned if you have fitted a mobile phone, or rather if you have fitted a car kit to mount a mobile/cellular phone.
It is really easy to get permanent live and switched live mixed up and after doing so, the classic symptom is a dead battery after 2-3 days.
This has certainly happened to me a couple of times.
