This new-to-me bike has a rewound (dual-output) stator and what I think is a BD dualsport kit. However, the electrical system is running at a very low output--the headlight is worthless in the dark and battery eliminator isn't charging. However, a couple nights ago when I started it up, it was really bright for about 30 seconds, then dropped back to low power. I haven't dived into the wires with a multimeter yet, but I was wondering if there are any 650R-specific gremlins to look for, like floating versus normal ground. Thoughts?
