Hey guys, 

Yesterday i tried removing my battery so I could diss-conect the trickle charger and everytime I'd get the battery out the alarm would go off. I ended up getting it off bu could someone tell me why it does that? And how to stop it from happening next time? 

 

Cheers. 

have the key turned on ready to run when disconnecting the battery.

 Warblade's right.

you gotta disarm the alarm before you can do anything cause the alarm has it's own battery and sposed ta scare off the burglers even if they try to disconect it.

thanks warblade and rider, ill give it ago next time i have to do anything.

IIRC the way to do it is you need to turn the ignition on and before the engine light goes out you need to pull the main fuse. Big orange one that clips in at the top left side of fuse box in my 08fxstc.

 I did mine by whipping the main fuse out when I turned the bike OFF.  

So switch on and wait for it all to come to life,

Turn it off,

Whip out the fuse before the alarm has time to arm,

It's now safe to disconnect the battery.

The above worked for me on my 2011 Dyna.

Cheers,

 Had the same experience and the HD mechanic said just let it scream until the back up battery goes flat. Doesn't take long.

yep, what they said
