Customer Question

I have a 2002 ARC 3.0l that alarms unexpectedly. I removed the anti-theft siren unit from the front left fenderwell, cut it open (sealed unit) and tested the batteries. They tested at 3v each. Since this is the battery rating, I reassembled the unit, cleaned the terminals, and reinstalled it. The next day my alarm siren went off again, at 1AM. Very Annoying. Could it be something else? Or should I replace the siren?

I am sorry that you have not been helped yet. I just came online and saw your question

It is rarely the siren. Most of the time it is the hood switch(see attached for location), or one of the door switches. Disconnect the hood switch and insert a jumper wire between the terminals on the harness side connector for the hood switch. If alarm no longer goes off randomly, replace the switch.

If still going off, then repeat at each door switch(see attached)
