Question about Vehicle Parts & Accessories
Ran battery down on 04 Acura MDX. Installing new battery. When battery is connected the security alarm sounds.
You didn't say whether this was a factory or an aftermarket security system. Factory systems can usually be reset by using the key in the driver's side door, and turning key to "lock" then "unlock". An aftermarket system may benefit from having the ignition key in the "ON" or "RUN" position.

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!
