My Uly was a garage queen before I bought it a few months ago...an '08 with only 8,000 miles. The PO had it serviced just about every year (brake, oil, trans fluid change, overall inspection).
The other day as I was riding, the CE light came on. I mostly ignored it since the bike was running fine (I had not yet installed the Buelltooth). Later in the day, it failed to start (just clicking). I charged the battery and reinstalled it and it ran fine for the few miles home (I had left it at work due to the non start issue).
Since then, I installed the Buelltooth and got it to pair to ECMDroid. The only code from the ECMDroid was the aforementioned "16 / battery voltage too low".
The battery was new a/o August 2018 but I'm unsure how well the PO took care of it (he claimed to have kept it on a battery tender and there was a pigtail attached to the battery).
I tested the battery using the procedures in this post
-30A battery fuse looked great.
-08 Uly...I don't think I have the #77 connectors in the same place (not visible when I removed the pulley cover)
-i did not clean the grounds
-removed derby cover, smelled like regular oil
-battery had completed charging on a smart charger and was around 13.5V before installation...then I rode it around 5miles/20minutes home
-ignition key on: 12.5V
-after starting and holding it around 1500rpm: 11.86V
Clearly the battery is discharging. I have VR on order (I live in Italy so it's a bit of a wait, the local HD dealer still has the Buell sign up but wanted over $200 for a VR with a 2 week wait).
Another clue: I'm on my third low beam bulb in the last 1000 miles.
Tomorrow, I will buy a new battery, charge it and install.
