Car Alarms: 1991 Mazda 626, Car Alarm, negative polarity, fuse box


Question
I bought this car 5 years ago and have never had this happen before.  I don't have a car alarm, but when I went to start my car my neighbors had disconnected my battery and horn because they said it had been going off for over an hour.  The horns and lights blinking. (I live way in the back and didn't hear it). What could have caused this? I took it into Firestone and they checked everything and said No, they don't see a car alarm either.  I'd like to disconnect whatever I can, so it doesn't happen again.  Can anybody help me?  We are truly stumped.

Answer
Ok, if malfunctioning now, odds
are, it will again. It sounds like
the factory alarm system (Mazda was mistaken)

Get out some basic install tools or get
a friend or a good technician
in there to do this.

Normally, you would insert the key in
the drivers door, turn left, then right
to disarm and reset it. If yours is malfunctioning,
you can disable it for good by doing the following:

The FACTORY ALARM DISARM WIRE IS
gyel/rd or lt grn/blk  |- negative polarity|
Located in the drivers door harness or
at the Factory alarm is built into the fuse box.

Once Located, splice into one of these wires with
a simular guage wire, and put it to
a solid chassis ground. This terminates
the OEM alarm functions entirely.

However, at this point, this car would be exceedingly
easy to steel, so I suggest you get an aftermarket
alarm system to protect it from here on in.

Have a good day.
