I have one ground from the lighting coil part of the stator to the engine right above the timing sensor. One from the front motor mount to the chassis and one from the recoil housing to the resonator mount on the exhaust. They are all 100%. Is the brown from the lighting coil on the stator what grounds the ECU? I do not see any other grounds. I downloaded the 2002 manuals to use for reference and testing. So far everything has checked out.
