Gentlemen, My 2001 SE Glide started chirping at me from time to time just sitting in my shop without the alarm set. Then a few weeks later, it started going off for a few seconds while I was riding it ( usually when I stopped at a light with the blinker on ) the siren quit chirping when I set the alarm with the fob so I replaced the siren unit. It started doing the same thing, only the first time I tried to ride it with the new siren it went off quite a bit just trying to pull out of the driveway forcing me to turn around. I killed the ignition and waited for it decide to stop going off and I unplugged the siren unit. A few seconds after unplugging it, the siren unit started going off again and the only way to shut it up was pull out the 9V battery. None of the cycle mechanics I have talked to have heard of this. The alarm system works fine, but just not with the siren unit plugged in. It all worked fine when I bought the bike last year, but I hardly ever used it. Any help would be appreciated. Bud C.
