Have the battery load tested (it's usually free) if it's OK, then start looking for a 12 volt accessory pulling power with the bike off. I'd start with things like GPSs and radios, then go to any electrical accessories that you've had added to the bike. If you have to go that route, it may take a while, cars and bikes aren't designed to easily troubleshoot electrical faults. That's why I do most of my own electrical work on my F3, I run power to a distribution point and then split it to different loads using connectors that can be opened and closed like the flip lever ones that Lamonster provides although I've gone him one better and gotten five-port fasteners to use as distribution points. I mounted three up under the left side panel with the safety instructions on it; one switched, one always hot and one ground. It makes working on things fast and easy and is high enough to stay dry. Oh a hint from thirty five years as a TELCO tech, ALWAYS label your wiring. What makes sense today can result in you spending hours tracing and cursing yourself in a few months or a year trying to figure out just what you were thinking when you did something. A couple of minutes with a label maker or sharpie is a great investment in peace of mind.
