I have an 02 super dyna glide with the factory alarm and smart siren. Never had a problem till the last few weeks. The siren goes off for no apparent reason. Even when the system is not armed. Sometimes it goes off while I'm riding. Gives new meaning to ride it like you stole it. Seems to be an intermittent problem. Last night it went off in my garage 10 times sitting still while is was unarmed. I brought it to the dealer a few weeks ago and the only thing they found were loose battery terminals. They tightened them up and sent me on my way. I told them I thought I'd be back and probably will. But I wanted to see if anyone has had a similar problem and knows the fix.
Thanks,
Lou

 

I'm really not sure, but... it could be the 're-chargeable' battery in the siren.
The battery life under normal conditions is approx 3-6 years.
The internal siren battery may not charge if the vehicle's charging system is
producing less than 12.5 volts.
A low or dis-charged battery might be causing the problem... you could replace it
just eliminate it from the equation.

 

+1 I agree with 08fxdf43202 i know for a fact that car alarms when the car battery is going dead the alarm will not stop going off!!!!

 

Thanks for the reply's.. I probably should've mentioned I changed the 9V in the siren and checked all the connections before I brought it to the Dealer. Also a new starting battery this spring.
