Here's my electrical issue: I picked up a headlight and tailight for a 07 250xcw. Since neither light worked once connected, I checked the front and rear harnesses for 12+ volts. Nothing there. Then checked across the voltage regulator. Still nothing. Then checked the yellow wire that comes up from the stator/lighting coil to a ground. Still nothing. I'm no electrical expert but at this point was guessing the issue was with the lighting coil. Fortunately, I have twin 07 xcw's so swapped the stator/lighting coil and fired up the bike again. Still no lights and no voltage at the yellow wire using the other stator/coil. I suppose both lighting coils could be bad but am wondering if I'm even diagnosing this correctly? Am at loss and am hoping I'm overlooking something obvious. Any thoughts?
