SOURCE: Hi, my name is Grace
I had the same problem Grace and even mechanics could not figure it out at first. I called 3 Acura dealers to find answers.
Mine began acting up when a door lock broke and when it broke, the alarm started going off out of the blue.
But.....I want you to know that the drainage of electrical that the alarm drained my battery. Jumpstarted battery and alarm would immediately start back up and drain it again. In the end, it fried my alternator. It was pretty crazy because the radio was going off and on by itself with the alarm blaring and no way to shut it off.
Answer is there is no way to remove the alarm system because it is all integrated in by the factory, Acura dealers told me. Your car thinks it has been broken into once the alarm goes off like that, so keeps doing it. The fix was to insert my key into the driver or passenger door lock and turn the key back and forth 3X. That resets the alarm and stops the whole problem.

If it's a cheap aftermarket alarm, check for a red wire coming off the hot side of your battery with an inline fuse. If it's not, try to locate the alarm "computer" under the driver's side dash or nearby your fuse panel. You'll find a black box with a wiring diagram glued to the side, normally strapped to a wiring harness or other fixed element. If this is the type of alarm you have, you'll need to trace each wire coming from the alarm computer and unclip each fastener that's clipped to your vehicle's factory wiring. The trouble with these types of alarms is that they can get power from a number of sources (stereo, interior lights, etc.). Good luck with this one!

car battery light comes on, replace battery and the altenator is good, but the battery still gets drain, what could be the problem.

Main relay costs about $80. It is buried deep under the dash, hard to access and usually labor is about 1 hour to replace at a shop.
