After leaving the bike on a trickle charger over the winter, I decided to take the bike out around the block since the weather is much better. For some reason, the Yellow Engine light seems to stay on no matter what. It's been like this for almost a week a now. I rode the bike for 15-20 minutes each time in the past three days. I tried checking all the leads that were connected to the battery, and everything looks okay. The dash doesn't mention anything as to the reason why the light is on. Unfortunately, I don't have access to any tools where I can diagnose the problem. Has anyone else had the same issue, and if so, how did you fix it? Any and all feedback is greatly appreciated!
