Hey all, hoping someone can help me figure out what is wrong with my '03 Classic.

I recently got up to Michigan from Florida (where I haven't been having issues) and it's been chilly lately. The bike wasn't wanting to start in the morning when the temp was below 55 or so. I was thinking it might be the thicker oil I use in Florida, since if I left the bike out in the sun for several hours, it would generally startup. I was concerned about the battery (which I replaced last year) getting drained while trying to get it started, so I borrowed a maintainer from a co-worker and have had it hooked up for 2 days straight.

Well, I was off today, so I thought I'd go out and try to start the bike since it was a little warmer today. No dice. It was laboring while trying to start. Turning over, but barely. Only able to try a few times and then the bike just clicks and the display goes out, as if the battery was dead. Charger has been hooked up the whole time. I thought I'd check the spark plugs, just in case... only get on 2 of the 4 because I don't have the right socket with me, but the 2 I did look at didn't appear to be an issue.

I stood looking at the bike hoping something would come to me and I remembered it has a Kuryakyn WildThings FI controller. It came on the bike when I got it 3 years ago. Not sure of the model, but I looked online to see if I could tell if it was functioning properly. From what I can tell from the little info I could find, there's a green LED that should stay lit when the key is turned on. That light is blinking (I took a pic, rest assured, the light is blinking, not steady on) nonstop and I *think* it might be a connection issue, but since I'm not sure if the pdf I downloaded was even for this particular model, it's only a guess. I'm kind of thinking not, because it mentions yellow/white wires and I don't see those colors on the controller. I haven't lifted the tank yet to see what wires are there.

Anyway, I'm really perplexed and could use help. I'm dependent on the bike to get to work and this could become a much bigger issue for me if I can't get it ironed out. Any help is appreciated, and please let me know if there's more info that's needed.

Sounds like a battery issue. I charged my VTX battery (1 year old) for 2 days, charger told me it was good but it couldn't start the bike. Battery test said it needed charged; new battery fixed the issue. For good measure you may consider checking battery cables for integrity, corrosion, & voltage drop then cleaning the start switch contacts.
