Hmmmm....I hope the duct tape thing works, I'll give it a go. I just took the battery off my 888 to rob it for my ST.
Obviously I forgot to put it into service mode first and had to reconnect the battery and run into the house to get the keys. When I put it into service mode and took the battery off again, it gives out a couple of bleeps every 15 seconds, just like Fordie's.
The bike is not too far from my neighbours kitchen window, so I can't have the bugger going off like that until the internal alarm battery runs down...
I've got a similar thing with my wife's Hornet. Her switch is on the seat so as to protect the alarm unit, which sits under there. If I want to remove her seat, which would normally activate the alarm, I disarm the alarm as usual, and before it rearms, I remove the seat. The alarm then doesn't go off. I then either let the alarm rearm automatically, or rearm it myself, then press the large button. This puts it into ferry mode which means it's armed, but the motion sensor is disabled. Now I can fiddle under the seat or move the bike around. I use ferry mode whenever I clean it too as you can move the bike without the alarm going off, and you don't get the annoying service beep. When I removed the battery the alarm did sound but I just pressed the disable button and it shut up. Hope that helps.
Got a Datatool Evo, with that one you can fully arm it then press the Triangle(left button) & it will put it into ferry mode, ie you can work on it, move it etc, but just do not turn the ignition on, will set the alrm off.
