[QUOTE="69ST, post: 8927, member: 5"] Dan's right about the headlight being run directly from the alternator output. Still, even if your wiring has been modified at some point in its history, that alone shouldn't drain the battery if the lights are off. I've wired my bikes so that the headlights draw their power from the battery and haven't had any problems with battery rundown...even after sitting for weeks at a time. First thing to do is disconnect the battery from the bike when you think it's fully charged. Then let it sit undisturbed for the same duration and see what happens. If the battery is down on power, then it's either not holding a charge, only surface charged or simply not completely charged, when you believed it to be. If, on the other hand, it remains fully charged, then you'll have determine what's drawing current while the key switch is in the off position. A fully charged battery should indicate somewhere around 6.5Vor better. Below 6V indicates a discharged battery. [/QUOTE]
