Having a strange Alarm issue with my 2011 Ultra (FLHTK). Worked perfectly for 10+ years until this spring, the alarm goes off when I move the bike or stand it up etc. even while I have the fob right next to it in my pocket. It starts and rides just fine, it's only when I move the bike, it cycles with two sets of warning chirps followed by a full alarm cycle of say.. one min. or so, then it resets itself, a min. later it cycles again with two warnings then sounds a full alarm for about a min. then resets, this continues for five or six cycles then it seems to be fine (stops). This event has occurred on three separate occasions. I searched the forums/Google etc. came up with loose alarm antenna connection, I checked both the connection at the alarm module and at the alarm antenna both seem good. I've tried with both fobs present, fresh batteries in each fob, holding the fob at a variety of locations, can't solve the issue (stop the alarm).
Any suggestions will be appreciated, or if you could steer me to any existing threads with similar issues?
Thanks for reading.

 

It's telling you it needs a new battery in the alarm on the bike.

 

Make sure the Fib batteries really are good, and installed properly.

Thrn without moving the bike, with the Fib in range, turn on the ignition. If you get normal ignition on…the the fob and RC reception is good. Most likely then the alarm module is bad..

 

Does the alarm module itself have a battery? I installed an aftermarket horn to make the alarm process sound but the cheap horn I installed has no battery, I understand the OEM horns have a battery but mine does not. So I'm back to does the alarm module have a battery?
Any sense in trying a new Alarm antenna first?
Thanks for the reply.

 

No. Just OEM siren.

 

I think mine does what you are describing... even if I have my fob in my pocket, it will chirp at me if I move my bike around with the ignition off (I have the HD siren), and if I continue moving the bike around with the ignition off the siren is going to get loud... or I can turn the ignition on, while I move it, and everything stays quiet.
If the siren starts going off... and you have your fob, turn the ignition on... and the siren will stop, and reset... or better yet, turn the ignition on while moving your bike.

I don't know if it is by design, or just at that moment its not "seeing" the fob, so it chirps... but found it annoying enough, that I just turn the ignition on. I couldn't tell you if it did it before the siren was installed, but that was a few years ago and just the lights flashing wouldn't have been as annoying

when i experienced this it was informing me that my fob battery was low. changed the battery and it hasn't done it since.

 

He says he put fresh batteries in both fobs.

 

The Security System is a pain in the ***, I personally prefer a 45 and a spare clip, but that's me.
