Okay, so tonight I decide to hook up a simple pigtail to the battery so I can keep my battery charged. Simple? Not tonight. The new CVO Ultras have these new locking side bags, so it's not just a twist of the 1/4 turn fasteners and off comes the bag - no, you also need to "unplug" the connectors to the power locking system. So the wife holds the bag while I unplug the connector. You ask why the bag comes off? You need to remove the seat strap to remove the seat to get to the battery. Okay, I'll deal with it.
Now off comes the seat right? Nope. You have to disconnect the connector for the "heated" seat first, then the seat will come off. Okay, seat now off. On my old Ultra, the battery was right there under the seat - both terminals easy to disconnect and reconnect with pigtail connectors ends. Not so with the CVO. First the ECM must come off, as it sits on top of the battery. Then a tray needs to be removed that is being held in by a large torx head screw which is complete overkill to hold a plastic tray in place. Go figure, but so far so good, so I start to disconnect the terminals.
Then the alarm goes off!

The siren is sounding, my neighbors must be going crazy. And it staying on with BOTH terminals to the battery removed! I can't stop the thing! I'm feeling pretty stupid right about that time.

I try the fob, that doesn't work.

I read the manual, but it takes a rocket scientist to figure it out quickly. Finally, the book says it will go on and off for five minutes and then stop.
I finally get the pigtail on the battery and the alarm siren stopped for good. I put everything back together and put the battery on charge.

After that ordeal, the battery probably could use a good charge.
Dumb question - how can the alarm go off if there is no battery connected to the bike?

Damn Harleys...
