Have a 2003 BX2230 that belongs to a friend...went there last night & found the battery is fully charged, but when I turn the ignition switch on, there's nothing (fuel gauge doesn't move, no lights on instrument cluster). Checked the small group of fuses next to the batttery & they all seem fine. I don't have a wiring diagram for this thing, so I'm kinda in the dark now...anyone have a diagram they could post??
