This evening I hooked up the wiring harness for my new Gyde/Gerbing heated gloves. Clearly straight forward. Unscrewed negative, then positive. Connected positive then negative. I turned on ignition switch and tested gloves and they worked. I turned off the ignition switch and heard a weird noise that sounded sort off like a small fan winding down but it was more of a tick sound. It was in the area of the front cylinder head. I started the bike up and it idled fine. I didn't have a chance to test ride. It's something I never heard before. It's a 2015 FXDL.

Anyone have a clue as to what the sound may be?
